Critique of NTSB
US Safety Record
With
10,554 airline-related fatalities, the US has had almost twice as many as
Russia, five times as many a Canada, or the UK, or France, or India, or China,
and ten times as many as Germany, Venezuela, or the Ukraine. Many African
countries have been banned from landing in Europe because of their very poor
safety record, being 20% of fatal accidents versus only 3% of air traffic.
Only Africa Has a Worse "Safety" Record, Even in Kenya
The updated EU air safety list includes all airlines certified in 21 states, for
a total of 295 airlines fully banned from EU skies: Afghanistan, Angola, Benin,
Republic of the Congo, the Democratic Republic of the Congo, Djibouti,
Equatorial Guinea, Eritrea, Gabon (with the exception of 3 airlines which
operate under restrictions and conditions), Indonesia (with the exception of 5
airlines), Kazakhstan (with the exception of one airline which operates under
restrictions and conditions), Kyrgyzstan, Liberia, Mozambique, Nepal,
Philippines (with the exception of one airline), Sierra Leone, Sao Tome and
Principe, Sudan, Swaziland and Zambia. The list also includes 2 individual
airlines: Blue Wing Airlines from Suriname and Meridian Airways from Ghana, for
an overall total of 297 airlines.
Additionally, the list includes 10 airlines subject to operational restrictions
and thus allowed to operate into the EU under strict conditions: Air Astana from
Kazakhstan, Afrijet, Gabon Airlines, and SN2AG from Gabon, Air Koryo from the
Democratic People's Republic of Korea, Airlift International from Ghana, Air
Service Comores from the Comoros, Iran Air from Iran, TAAG Angolan Airlines from
Angola and Air Madagascar from Madagascar.
Africa once again reported the
world's highest rate
of fatal commercial aviation
accidents in 2013, despite increased local and international efforts to improve
air safety in the region.
Africa has just 3% of global air traffic. But African crashes accounted for
roughly 20% of the 29 accidents and 265 fatalities world-wide involving
passenger and cargo planes designed to carry the equivalent of at least 14
passengers, according to an affiliate of the Flight Safety Foundation, an
advocacy group for global aviation safety based in Alexandria, Va.
TWA Flight 841: the Plane that Fell From the Sky
The pilots who saved the lives of their
passengers had their own lives and careers destroyed ONLY because the HNTSA
asked Boeing to investigate their own faulty Boeing 727's aileron strut.
Predictably, Boeing claimed that it was
"impossible to fail", which NO reputable aircraft manufacturer should EVER be
allowed to utter. Needless to say, the NHTSA followed suit, and the
accident was blamed on the pilots.
Since then, the NTSB has gotten a bit more user friendly, and
perhaps too much so, because they now appear to be blaming accidents on
everything but the pilots or copilots.
Jewish pilot Crashed
Flash Airlines # 604
Did this Jewish general and pilot have an accident, or crash it on purpose?
Flight # 604 charter flight
Captain Kayliff? Kayo?
War hero, 7,000 hours?
Vertigo? Egyptians agree he was disoriented, but crew resource
management system which the law requires was never administered.
Was the very young Flight Officer really intimated by a Jewish Air Force
general?
The NTSB report issued March 2006 did not even cite the role of this Jewish
pilot, and instead stated it was a combination of factors.
However, European nations, who clearly disagreed with the NTSB assessment,
all agreed to ban dangerous African and Israeli airlines, who are
over-represented by 26 FOLD in airline crashes.
U.S. Summary Comments on Draft Final Report of Aircraft Accident Flash
Airlines flight 604, Boeing 737-300, SU-ZCF January 3, 2004, Red Sea near Sharm
El-Sheikh, Egypt. Quote from page 5 of 7:
"Distraction. A few seconds before the captain called for the autopilot to be
engaged, the airplane’s pitch began increasing and airspeed began decreasing.
These deviations continued during and after the autopilot
engagement/disengagement sequence. The captain ultimately allowed the airspeed
to decrease to 35 knots below his commanded target airspeed of 220 knots and the
climb pitch to reach 22°, which is 10° more than the standard climb pitch of
about 12°. During this time, the captain also allowed the airplane to enter a
gradually steepening right bank, which was inconsistent with the flight crew’s
departure clearance to perform a climbing left turn. These pitch, airspeed and
bank angle deviations indicated that the captain directed his attention away
from monitoring the attitude indications during and after the autopilot
disengagement process. Changes in the autoflight system’s mode status offer the
best explanation for the captain’s distraction. The following changes occurred
in the autoflight system’s mode status shortly before the initiation of the
right roll: (1) manual engagement of the autopilot, (2) automatic transition of
roll guidance from heading select to control wheel steering-roll (CWS-R), (3)
manual disengagement of the autopilot, and (4) manual reengagement of heading
select for roll guidance. The transition to the CWS-R mode occurred in
accordance with nominal system operation because the captain was not closely
following the flight director guidance at the time of the autopilot engagement.
The captain might not have expected the transition, and he might not have
understood why it occurred. The captain was probably referring to the mode
change from command mode to CWS-R when he stated, “see what the aircraft did?,”
shortly after it occurred. The available evidence indicates that the unexpected
mode change and the flight crew’s subsequent focus of attention on
reestablishing roll guidance for the autoflight system were the most likely
reasons for the captain’s distraction from monitoring the attitude".

Valujet Flight 592 Crash CAUSED by FAA Largesse, Yet Shut
Down by the FAA
WHO was responsible for 110 deaths?
Valujet = ZERO percent
FAA = 100%
At the time of the crash, NOBODY, not Valujet, and not even
the NTSB, could possibly have known that packaging oxygen breathers in bubble
wrap WOULD cause a fire, and that packaging them with NO bubble wrap would have
PREVENTED a fire. And yet the FAA shut down Valujet because they DID
follow ALL FAA regulations, including the one about not putting fire detectors
and fire sprinklers in cargo holds.
Ironically, had Valujet IGNORED FAA instructions about not
putting detectors and sprinklers in cargo holds, and instead installed them as
common sense would have demanded them to do, this accident could NOT have
happened.
So rather than shutting down Valujet which harmed millions of
employees, travelers, and stock holders, let's shut down the FAA which will make
the airways safer AND cost only a few plum federal jobs.
300 PLUS Almost killed by BLACK MASS MURDERER



Flight Engineer Auburn Calloway knew his career was about to end. His employer,
Federal Express, had recently uncovered a series of irregularities and outright
falsifications in both his original employment application and in hundreds of
hours of flight records. He was ordered to appear at a disciplinary hearing in
the second week of April, 1994. He understood that the likeliest outcome of such
a hearing would be his termination, and subsequently the loss of his FAA flight
certification.
His solution was as simple as it was horrifying. He would provide for his family
financially, end his own life, and in the process he would punish FedEx in the
worst way imaginable.
April 7, 1994: FedEx Flight 705 was scheduled to depart the company’s home hub
of Memphis, Tennessee for a routine flight to San Jose, California at a little
after 3:00 in the afternoon. As Captain David Sanders, First Officer Jim Tucker
and Flight Engineer Andy Peterson boarded the aircraft, they were somewhat
startled to see Auburn Calloway already on board, settled into the Flight
Engineer’s station and initiating pre-flight procedures. Although it was not
unusual for FedEx employees to hitch rides on regular flights - a practice
termed “jumpseating” - it was a pronounced breach of protocol for such
deadheaders to interfere with flight operations. They said nothing, though, and
Calloway wordlessly gave his seat to Andy Peterson. He strapped himself into a
jumpseat aft of the cockpit. At his feet was a guitar case, the only baggage he
had brought on board.
Less than thirty minutes into the flight, the bloodbath began.
The weapons that Calloway chose for his attack seem bizarre and indicative of a
deranged mind. When one understands the cold calculation of his plan, though,
the terrible logic becomes clear. The guitar case contained two claw hammers,
two sledge mallets, a knife and a speargun. Calloway could have easily smuggled
a gun on board Flight 705, but he wanted to inflict no injuries that were
inconsistent with an air crash—for that was at the heart of his plan. Having
already purchased thousands of dollars worth of death and dismemberment
insurance, he planned to bludgeon to death the crew of Flight 705, then crash
the DC-10 into the terminal of the Memphis Superhub. His own death would secure
his family’s future, while the devastating crash would likely destroy FedEx. But
first he had to kill the crew; it was their will to survive that foiled Auburn
Calloway’s plan.
None of the three men heard Calloway enter the cockpit. Sanders suddenly became
aware of a struggle, and heard the awful sound of hammer blows raining down upon
his crewmates. He turned to see both men slumped in their chairs, injured
terribly, and a blood-soaked Auburn Calloway moving toward him.
Calloway swung wildly at Sanders. Some of the blows landed, some were deflected.
The plane lurched as Sanders desperately tried to defend himself. Then something
happened that Calloway had not counted upon. Tucker and Peterson recovered and
began fighting back. Calloway was surrounded; he flailed about with the hammer,
still inflicting gruesome injuries. The men would not give up, though, and
Calloway at last retreated from the cockpit.
Sanders, Tucker and Peterson scarcely had time to register what had
happened—they didn’t even have a chance to radio for help—before Calloway
returned. Now armed with the speargun, he threatened the men who were advancing
upon him once again.
“Sit down! Sit down! This is a real gun, and I’ll kill you.”
Andy Peterson was bleeding from nearly a dozen wounds to his face and head. He
teetered on the brink of consciousness, and couldn’t even see Calloway, who was
only a few feet away. He could see the speargun, though—he could see the barbed
steel shaft that protruded from the barrel just inches from his face. He grabbed
at the weapon and threw himself on top of Calloway.

Captain Sanders joined the fray as Jim Tucker struggled to control the airplane.
By now, Tucker’s right arm was nearly useless as the grave injuries to his skull
brought on paralysis. He knew that his wounded crewmates could not last long
against Calloway, so he assisted the only way he could. He pulled the control
yoke all the way back to his chest, and rolled it to the left.
The DC-10 was executing a barrel-roll at nearly 400 miles per hour—something the
aircraft had never been designed to do. Peterson and Sanders were shouting “Get
him! Get him!” to each other, as the three struggling men were tossed about the
galley area, alternately weightless and pressed upon by three times their weight
in G forces. By now, the aircraft was inverted at 19,700 feet, and the alarmed
air traffic controllers in Memphis were desperately calling for Flight 705.
Tucker initiated a series of wild maneuvers. He knew he had to keep the craft’s
motion unpredictable, or Calloway would simply wait for the roll to end then
resume his attack. Tucker abruptly threw the yoke forward, and sent the plane
into a vertical dive. He realized then that the throttle controls, located to
his right, were pressed forward to their stops; he could not reach them with his
limp right hand. The diving DC-10 accelerated past 500 miles per hour, then past
the instruments’ capacity to register. Flight 705 was now traveling faster than
any DC-10 had ever gone, and was undergoing velocity stresses that the airframe
could not sustain.
Somehow, Tucker pulled from the dive, then reached across the yoke with his left
hand to cut speed. At last he grabbed a radio headset and called Memphis.
Flight 705 turned back for Memphis and was cleared for any runway. No one on the
ground understood what had happened—all they knew was that an unnerved crew
member had reported some sort of “attack,” and had requested an emergency
landing.
A paramedic boarded the plane, and found blood and gore everywhere he looked.
Sanders and Peterson were laying on top of a still-struggling Calloway, while
Jim Tucker sat shaking at the co-pilot’s station. Calloway was handcuffed and
hauled away.
Within days, the FBI searched Calloway’s apartment and uncovered detailed
evidence of his plan. Calloway would attempt to have that evidence suppressed
for lack of probable cause, but was unsuccessful. He was convicted on a
two-count indictment of air piracy and interference of flight operations. Auburn
Calloway was sentenced to life imprisonment without the possibility of parole,
and is currently residing at the federal penitentiary in Atlanta.
Sanders, Tucker and Peterson had survived a suicidal act of piracy, but at a
terrible cost. Sanders suffered multiple lacerations to his head, had been
stabbed in his right arm and had a dislocated jaw. His right ear had been almost
completely severed.
Jim Tucker’s skull was severely fractured. The right-sided paralysis would pass,
but he would experience ongoing motor-function impairments to his right arm and
leg. He was also blinded in one eye.
Andy Peterson also suffered a skull fracture, as well as a severed temporal
artery.
None would ever fly again......
Flying While Black
Africa still is the least safe continent,
accounting for
22% of all fatal airliner accidents while the continent only accounts for
approximately 3 percent of all world aircraft departures.
This is also reflected by the fact that, on average, African nations score 4.5
on a scale of 10 in aviation safety audits performed by the International Civil
Aviation Organisation (ICAO). And the airlines of several nations are not
allowed to fly into the E.U. (14) and United States (6).
The Aviation Safety Network is an independent organisation located in the
Netherlands. Founded in 1996. It has the aim to provide everyone with a
(professional) interest in aviation with up-to-date, complete and reliable
authoritative information on airliner accidents and safety issues. ASN is an
exclusive service of the Flight Safety Foundation (FSF). The figures have been
compiled using the airliner accident database of the Aviation Safety Network,
the Internet leader in aviation safety information. The Aviation Safety Network
uses information from authoritative and official sources.
Flying While Black: David Burke Mass Murderer of
44 on PSA Flight 1771

A Call comes in to the San
Luis Obispo County, California
Sherrif's Office citing a small
plane crash in the mountains
of southern California. Detective Bill Wammock is the first to arrive on the
scene. He recalls “nothing that resembled an airliner... we went on for hours,
before we heard the news reports of a missing airliner, believing that we were
dealing with a small airplane full of newspapers that had crashed. We saw no
pieces of the aircraft that were larger than, maybe, a human hand. It did not
look like a passenger aircraft.”
Two days later, an FBI Agent working the scene found what appeared to be the
barrel and trigger of a handgun. Forensic Analysists examined the pieces, and
found a small peice of skin wedged between the trigger and the barrel. By
matching the skin prints to the passenger manifest, investigators were able to
conclude that the gun had been in the hand of USAir employee David
Burke at the time of impact.

December 7, 1987, was not a typical day for USAir employee David
Burke. Two weeks prior, Burke had been placed on unpaid leave, awaiting the
outcome of an investigation into whether he had stolen $68.00 from a drink fund set
up by Flight Attendants.
The date of Burke's appearance before the Board of Appeals at USAir was today.
In the hearing, Burke admitted to the
act and
pleaded for leniency, citing his family's well-being. Despite telling the
members of the committee that he was “regrettably sorry,” and that his “children
would have no one to support them,” Burke's pleas for his job went unheard, and
he was summarily dismissed by his supervisor, Raymond Thompson. As Burke left
his office after the hearing, Thompson's secretary wished him to “have a nice
day.” Burke paused, turned around, and replied “I intend on having a very good
day.”
David Burke then purchased a ticket on Pacific Southwest
Airlines flight 1771,
a daily non-stop along PSA's “Pacific Highway” between Los Angeles and San
Francisco. This flightwas also taken
by Burke's supervisor, Raymond Thompson, every day on his commute home from the
USAir Headquarters at LAX.
Using his USAir employee credentials,
which had not been seized and were later found at the crash site, David Burke
bypassed security at Los Angeles International Airport and stepped aboard the
BAe-146 aircraft, armed with a loaded 44-magnum pistol. Upon entering the
aircraft, Burke scrawled a note onto an air-sickness bag which read:
“It's kind of ironical, isn't it? I asked for leniency for my family, remember?
Well, I got none, and now you'll get none.”
As the aircraft reached its cruising altitude of 29,000 feet, Burke calmly
vacated his chair and made his way to the lavatory, dropping the air-sickness
bag in his supervisor's lap as he passed. Moments later, he emerged with the
handgun, and immediately shot Thompson. The sound of the gunshot is picked up on
the cockpit voice
recorder,
and seconds later the sound of the cockpit door opening
is heard. A female, presumed to be a FlightAttendant,
advises the cockpit crew that “we have a problem.” The Captain replies with
“what kind of problem?” Burke then appears at the cockpit door and
announces “I'm the problem,” simultaneously firing two more shots that fatally
injure both pilots.
Several seconds later, the CVR picks up increasing windscreen noise as the
airplane pitches down and begins to accelerate. A final gunshot is heard as
Burke fatally shoots himself. Airspeed continues to build until 13,000 feet,
when traveling at a velocity of 1.2x Mach, the aircraft breaks apart and the Flight Recorders
cease functioning.
All 44 passengers and crew aboard PSA Flight 1771
died as the aircraft crashed into a Farmer's field in the Santa Ana Hills. The
accident spelled the end of Pacific Southwest
Airlines, which in April of the following year was absorbed into USAir. A
federal law was passed which required “immediate seizure of all airline employee credentials”
upon termination from an airline position.
Most importantly, however, the Federal Aviation Administration adapted policy to
require that all members
of any airline flight crew,
including the Captain, be subjected to the same security measures as are the
passengers.
ILS
Rather than spending a few hundred thousand dollars to simply
maintain the nation's ILS systems which could have saved THOUSANDS of lives, we
instead spent $85 Billion for TSA which saved NO lives and
simply pissed off EVERYONE [Congressmen, great-grandmothers, and children]
Rather than looking like the world's policeman or superpower,
we are the laughing stock of nations
250 ALMOST Killed with Out of Service ILS
"On July 25th, flight EVA28, a
Boeing 777 flying from Taiwan to SFO, was on the final approach for runway
28L when they were alerted by ATC that they were only at 600ft above the ground
at less than 4NM from the threshold. SFO's tower directed
the flight crew to climb immediately and
declare missed approach. Assuming they were flying at 140 knots (typical
approach speed of a 777), they were less than 2 minutes from the runway and at a
3 degree angle (approx 500ft/min descent), about a minute from impact. This is
the same type of aircraft and runway used by the crashed Asiana flight. Similar
weather conditions and awfully similar flight path. Is there a structural
problem with computer-aided pilot's ability to fly visual approaches?"

Sequester: It's More Than Flight Delays, It's Flight Danger
I have in my hands a copy of a letter from US Transportation
Secretary Ray LaHood discussing with the FAA how Obama's mandatory
furloughs will work. For example, if an airport experiences
some serious electrical problem with its navigation lights, or
system, emergency repairs will have to wait until the furlough day
is over.
That might sound bad in the abstract, but consider how it will
affect you if you are in the air, about to land and instead of
scrambling a team of electricians to make sure your pilot can safely
find the runway you are left in the hands of a guy trained to land
with the assistance of navigation beacons but now has to actually
fly the plane onto the runway in rain, fog, darkness or all three of
the above. That is what is happening.
Sure, the media will tell you that Obama's version of sequestration
will result in flight delays and some inconvenience for travelers,
but the risk to safety is a far bigger problem, and his
administration is more than willing to put Americans in harms way to
make a point.
You ought to call your Congressman today and insist that they take
every step necessary to protect the lives and safety of airline
passengers by re-directing funds away from Obama projects like
sending F-16's to the Muslim Brotherhood and spending that money on
our own citizens and their welfare.
God forbid, but if a plane goes down, blood will be on his hands.

San Fran Plane Crash Predicted Here?
When that Boeing 777 crashed and burned at the San Francisco Airport
the first person blamed was the fairly new pilot. But now the
investigation will include a hard look at what role the shut down of
the automatic glide path system at the airport played in the
tragedy.
San Francisco International Airport, with its tightly spaced
runways that extend right up to the water, requires more skill
for landing than most of the nation's big airports, experienced
airline pilots say. That challenge was further complicated by
the shutdown of a ground-based instrument landing system and the
movement of runway thresholds prior to the crash Saturday of a
Korean airliner.
The instrument landing system, or ILS, uses radio signals to
create a three-dimensional "glide slope" for planes to follow so
they aren't too high, too low or too far to the right or left.
The ILS for runway 28 left, where the plane crashed, had been
shut down since June and the beginning of the runway was moved
300 feet to the west to accommodate construction at the airport,
according to pilots who use the airport. National Transportation
Safety Board Chairman Deborah Hersman said Sunday investigators
will look at what role, if any, the absence of the ILS may have
played in the accident. [myway.com]
Why was the ILS system down? I hope it wasn't what
I predicted.
To be
further in tune with the facts here.... There are more approach aids than
the ILS. Safety in aviation is layered and in the case of approach aids there
are at least three more ways a pilot should be able to use to judge his approach
and correct. There are the VASI lights which tell you if you are too high or
low. There are the markings on the runway, which are of standard sizes and
locations which aid the pilot who is looking out the windows. Then there is the
"visual picture" that the pilot will have seen many times before when landing,
even if only in the simulator.
Any of these *should* have been enough to safely land.
My guess is that what really happened here is a combination of ATC directions
and pilot errors. ATC likely directed a short approach which started pretty high
making it difficult for the pilots to properly stabilize the approach. The
inexperience of the pilot in command contributed to the issue because it took
him longer to make all the complex adjustments, get the gear down, flaps down,
get on the glide path at the proper airspeed and complete the landing checklists
and he lacked experience to recognize what was happening. The PIC got behind the
aircraft and by the time they realized the sink rate was way to high they where
to low and slow to recover. They landed way short.
This is an old story, told time and time again. A flying aircraft does not wait
for the pilot who doesn't keep ahead of the situation. Landing and take off
phase of flight are fast paced (compared to other phases) and also the least
forgiving of falling behind. The PIC fell way behind and failed to fly the
aircraft properly. He failed to recognize the danger and deal with the problem
and was lucky to survive. In this case I don't think ILS wold have mattered.
Out of Service ILS Kills 96 People on Polish Air
Force Jet
The 2010
Polish Air Force Tu-154 crash occurred
on 10 April 2010 when a Tupolev
Tu-154M aircraft
of the Polish
Air Force crashed
near the city of Smolensk,
Russia, killing all 96 people on board. These included president Lech
Kaczyński and
his wife Maria,
former president Ryszard
Kaczorowski,
the chief of the Polish
General Staff and
other senior Polish
military officers,
the president of the National
Bank of Poland,
Poland's deputy
foreign minister, Polish
government officials,
18 members of the Polish
parliament,
senior members of the Polish clergy, and relatives of victims of the Katyn
massacre.
They were en route from Warsaw to
attend an event marking the 70th anniversary of the massacre; the site is
approximately 19 kilometres (12 mi) west of Smolensk.
Smolensk North Airport is a former military airbase now in mixed
military-civilian use. At the time of the crash the airport was not equipped
with a Western-style instrument
landing system (ILS);
the airport used to have a Russian version of ILS, but this system was
decommissioned upon the airport becoming a joint civil-military airfield.[1] The
Polish aircraft was modified to use Western-style ILS.[3] A non-directional
beacon system (NDB)
was installed at the airport,[4] but
such a system can be used only for a non-precision
approach to
the runway, as its antennas are situated on the opposite ends of the runway and
thus give only basic directional information about a landing plane's position
relative to the axis of the runway. Since it is a navigational aid,
not a landing aid,
it remains the crew's responsibility to keep track of the plane's altitude.[5] The
airport was equipped with both surveillance and landing radar.[1] The
lowest available approach minimums were 100 meters (330 ft) lowest cloud base
and 1,000 meters (3,300 ft) visibility.[1]
3 Killed on National Airlines Flight 193 SOLELY because of
ILS being down
LUCKILY, 55 of 58 passengers
did survive, but many had serious problems because of it.
214 of 237 Killed in Guam on Korean Airlines Flight 801 on
Boeing 747
There was heavy rain at Guam so visibility was significantly reduced and the
crew attempted an instrument landing. The glideslope Instrument
Landing System (ILS) in runway 6L was out of service; however, the captain
believed it was in service and at 1:35 am managed to
pick up a signal which was later identified to be from an irrelevant
electronics device on the ground. The crew noticed that the aircraft was
descending very steeply, and noted several times that the airport "is not in
sight". Despite protests from the flight engineer that the detected signal was
not the glide-slope indicator, the captain pressed on[11] and
at 1:42 am, the aircraft flew into Nimitz Hill, about 3 nautical miles (5.6 km)
short of the runway, at an altitude of 660 feet (200 m).
The U.S. National
Transportation Safety Board (NTSB)
investigation report stated that the ATC Minimum
Safe Altitude Warning (MSAW)
system at Antonio B. Won Pat International Airport had been deliberately
modified so as to limit spurious alarms and could not detect an approaching
aircraft below minimum safe altitude. The captain also failed to follow a normal non-precision
approach and
prematurely descended to impact a hillside short of the runway. Contributing to
the accident were the captain's fatigue and Korean Air's lack of flight crew
training, as well as the intentional outage of the Guam ILS Glideslope due to
maintenance. The crew had been using an outdated flight map, which stated that
the Minimum Safe Altitude for a landing aircraft was 1,770 feet (540 m) as
opposed to the correct altitude of 2,150 feet (660 m). Flight 801 had been
maintaining 1,870 feet (570 m) when it was waiting to land.
74 Killed on Korean DC-10 In Tripoli Because the ILS Was Out of Service
They were only lucky that
not all 199 on board were killed.
101 Died Decembar 1998 / Thai Airways Flight 261 / Surat
Thani, Thailand / Airbus A310-204
The aircraft crashed while attempting its third non-precision approach to Surat
Thani. The ILS was
out of service for maintenance, which necessitated the use of the less
accurate VOR approach by the crew. Crew fatigue having completed two previous
approaches unsuccessfully.
Bhoja Air B732 Crash at Islamabad kills 127 Because of ILS
Being Down
Firstly, the aircraft impacted terrain about 5 km short of Islamabad's runway 30
near Jinnah Gardens, completely broke up, burst into flames and came to rest in
Hussain Abad Village at around 18:45 PST. Around 50 houses onhttp://blogs.dunyanews.tv/?p=3959+
the ground are reported to have been destroyed in this crash. Reports from local
authorities confirmed there have been NO fatalities on the ground however, all
passengers and crew of this flight perished in the crash. Different report came
through as to how many passengers and crew were on board this Boeing 737-236(A)
aircraft. According to an official list released by the airline, there were 121
passengers and 6 crew.
34 killed with out of service ILS
1986 Mozambican Tupolev Tu-134 crash
Around 21:15 the navigator stated that the distance to Maputo was 60 kilometres
(32 nmi). Over the next few minutes, there were several comments from the crew
indicating that they believed the navigational aids at Maputo were unavailable:
the captain stated that "there is no Maputo" and "electrical power is off,
chaps!", while the navigator reported that the Instrument
Landing System (ILS) and Distance
Measuring Equipment (DME) were
switched off and that the non-directional
beacons (NDBs) were not working.[11]
Landing clearance and
crash
Shortly after 21:18, the aircraft reached 3,000 feet in its descent, and the
crew informed the Maputo controller that they were maintaining that altitude,
however the airplane continued to descend.[citation
needed] The
Maputo controller granted clearance to the flight for an ILS approach to runway
23,[11] but
after the flight crew reported the ILS out of service, the controller changed
the clearance to a visual
approach to runway 05. During
this time, the navigator stated the distance to Maputo as 25–30 km (16–19 mi),
the captain remarked that something was wrong, and the co-pilot said that the
runway was not lit.[12]
The crew radioed the Maputo controller and asked him to "check your runway
lights". Around 21:21 the navigator stated the range to Maputo as 18–20 km
(11–12 mi), and the flight repeated its request to Maputo to check runway
lights. Upon reaching an altitude of 2,611 feet (796 m) AGL the Ground
Proximity Warning System (GPWS) sounded
and remained on, and although the captain cursed, the descent continued.[13]

Alcohol and Other Drug Use in Commercial Transportation
James E. Hall
Chairman, National Transportation Safety Board, Washington, D.C. 20594 USA
ABSTRACT
Quite a bit of progress has been made in the United States in reducing the use
of alcohol and drugs by commercial vehicle operators in all modes of
transportation over the past few years. Drug use prevention and testing programs
have been required by the Federal Government since the mid to late 1980's. More
than 7,000,000 employees in safety-sensitive jobs are covered by the required
programs.
Random drug testing of rail workers in 1993 continued to show a reduction in the
number of those testing positive for the fourth consecutive year. The positive
rate was again less than 1.00 percent. This percentage is down from 6 percent in
1988. The U.S. Federal Aviation Administration reported that 1993, was the
fourth year in a row that aviation workers tested positive at a rate less than
one percent. Because of these low rates, new regulations that became effective
in 1995, will permit the random testing rates for
those industries to be reduced from 50 percent to 25 percent. In the trucking
industry, one survey conducted by the American Trucking Associations, compiled
drug testing data from its member companies for the year 1990. A positive rate
from random tests was 2.5 percent. As in the other industries, marijuana was the
drug of choice followed by cocaine. More recently, the Federal Highway
Administration conducted a four State roadside random pilot drug and alcohol
testing program. Through the end of 1993, the positive rate for drugs was 3.8
percent and for alcohol the positive rate was 0.18 percent. Earlier studies in
the trucking industry had found considerably higher positive testing rates.
This paper will discuss the progress that has been made and review current
developments in the field and discuss new testing requirements.
INTRODUCTION
Much has changed in the United States since we reported to you at T-92. Indeed,
there have been significant changes in alcohol-related crashes in both
commercial and non-commercial areas of highway safety and in transportation
safety in general. There have been similar significant changes in employee drug
and alcohol testing programs and in the rate of positive drug tests in
commercial transportation over a long period of time. Until recently, very
little was known about the use of impairing drugs (including alcohol) by the
operators of railroad trains, airplanes, ships and heavy trucks. In the United
States, the data indicated that a significant problem existed and that strong
action was required to control it.
I have the honor to chair the National Transportation Safety Board (NTSB). The
Board is an independent accident investigation agency chartered by Congress to
investigate transportation accidents, determine their probable causes, and make
recommendations to prevent their recurrence. We have no regulatory authority and
no financial incentives to promote our recommendations. Keep that in mind as I
address alcohol and other drugs in the commercial transportation system and as a
context in which progress has been achieved.
We have already reported to you that the Safety Board began documenting the
abuse of alcohol and other drugs in transportation accidents in the 1970's. By
the early 1980's, it became clear that a problem existed in all modes of
transportation and that not much was being done about it. In 1983, the Safety
Board recommended that the Department of Transportation (DOT) issue rules to
prohibit the use of alcohol or other drugs while on duty or for a specified
period before duty and to require toxicological tests on all employees
responsible for train operation. In 1985, the Federal Railroad Administration
(FRA) of the DOT issued a final rule on "Control of Alcohol and Drug Use in
Railroad Operations." The rule required alcohol/drug testing after accidents,
for reasonable cause, and for those applying for employment. Following
additional recommendations by the NTSB, the DOT in 1988, issued drug testing
rules for more than 4,000,000 persons working in safety sensitive occupations in
all areas of commercial transportation (Sweedler,
1992).
As you may know, the U.S. testing rules apply to Federal transportation
employees and to private sector transportation employees in safety-sensitive
positions. The original rules specified urine tests for the presence of
marijuana, opiates, cocaine, amphetamines, and phencyclidine (PCP). In addition
to the pre-employment, post-accident, and reasonable cause tests required for
railroad workers, the rules added random testing to all modes, including
railroad. The random test rate was 25 percent of covered employees in the first
year and 50 percent in subsequent years. There were many differences in the
rules among the various transportation modes including a lack of test result
reporting in all modes except aviation and rail and omission of alcohol tests in
all modes except rail. Further, the rules do not separate post-accident testing
for more comprehensive blood testing as requested by the NTSB. However, as a
result of landmark legislation, many of the rules changed.
The Omnibus Transportation Employee Testing Act of 1991 was sparked by the
derailment of a New York City subway train. The train operator had a BAC of 0.21
percent more than 13 hours after the crash. The Omnibus Testing Act is the
legislation that changed the face of alcohol and other drug testing in the
United States. The legislation required the DOT to issue regulations to include
testing for alcohol, the most commonly used and
abused substance in the United States. It expanded the drugs for which tests
would be conducted from a maximum of five to a minimum of five and allowed for
expansion to a greater number based on analysis by the Departments of
Transportation and Health and Human Services. Mass transportation was
specifically included in the drug testing programs to override a court decision
that the Federal Transit Administration lacked specific regulatory authority in
this area. It did not include the commercial maritime industry as regulated by
the United States Coast Guard. Nearly 8 million transportation personnel in
safety sensitive positions are now included in the alcohol and other drug
testing program. Notably, every holder of a commercial
drivers license (CDL) is included. That means every driver of a bus and
large truck is now subject to testing regardless of whether the driver operates
in intra or interstate commerce (Federal Register, 1994).
During the regulatory process of implementing the legislation, a number of key
changes were made in the commercial transportation alcohol and drug testing
system. The drug test rules now allow the random drug test rate to be reduced
from 50 percent to 25 percent of covered employees if the industry-wide drug
test positive rate on random tests is below 1 percent for 2 consecutive years.
When an industry qualifies for the 25 percent testing rate, it must maintain the
positive rate below 1 percent. If it doesn't, the random test rate will increase
to 50 percent of covered employees. All transportation industries are now
required to report test results.
Alcohol testing is the major change required by the Omnibus Testing Act. In
general, the rules implementing the act prohibit covered employees from
performing safety sensitive functions: 1) when test results indicate an alcohol
concentration of 0.04 or greater; 2) within 4 hours after using alcohol (8 in
aviation); 3) while using alcohol on the job; 4) during the 8 hours following an
accident if their involvement has not been discounted as a contributing factor
or until they are tested; and 5) if they refuse to submit to required alcohol
tests. Employers must remove an employee from the safety-sensitive function if
they violate any of these prohibitions and keep them off duty until they have
met the conditions. If an employee has an alcohol concentration of 0.02 or
greater, but less than 0.04, or is otherwise impaired by behavior, speech, and
performance indicators, that person is removed from duty for 8 hours or until a
test result below 0.02 is obtained. The rules require employers to conduct
pre-employment, reasonable suspicion, post-accident, return-to-duty, and
follow-up alcohol testing. The random alcohol test rate for covered employees
was set at 25 percent. However, this rate could be reduced to 10 percent if the
industry-wide random test positive rate is below 1 percent for 2 consecutive
years. I hasten to point out that there are differences in each mode of
transportation that are specific to that mode. For additional detail, the rules
were published in the Federal Register on February 15, 1994.
In general, the rules require implementation on January 1, 1995 for large
employers (generally 50 or more covered employees) and January 1, 1996 for all
other employers. All other existing drug testing rules and alcohol testing in
rail remain in effect until the new rules are implemented. Certain
transportation industries have filed suit regarding certain aspects of the
rules. For example, some trucking industry organizations objected to
pre-employment alcohol tests as "an intelligence test." The Secretary of
Transportation has supported elimination of pre-employment alcohol tests as an
unnecessary burden on the industry.
I am able to report on some exciting results in two industries where drug test
results have been reported for several years and on a special program in the
trucking industry.
AVIATION
At T-92, we reported that the felony conviction of three former Northwest
Airlines pilots of flying a passenger jetliner while intoxicated brought new
focus to the problem of flying under the influence of alcohol.
(ICADTS Reporter, 1991). In 1990, the FAA issued new
rules designed to identify and ground pilots involved in alcohol or drug-related
motor vehicle offenses that result in convictions or administrative actions.
Pilots applying for a medical certificate must consent to the release of
information from the National Driver Register (NDR) to enable the FAA to obtain
and review motor vehicle offense information pertaining to the applicant. The
FAA can deny or take action to suspend a certificate of a pilot who receives two
or more alcohol or drug-related convictions or administrative actions within a
3-year period (ICADTS Reporter, 1990). To date, over 1,000 cases have been
referred to the FAA's chief counsel for administrative action (FAA, 1994).
From 1983 to 1988, no pilot in a fatal commuter crash tested positive for
alcohol. However, the pilot of one of these fatal crashes did test positive for
a metabolite of cocaine. In 1988, a Trans-Colorado Airlines, Fairchild Metro
III, operating as Continental Express, with two crew members and 15 passengers
on board, crashed short of the runway at Durango, Colorado, killing the two crew
members and seven passengers. The NTSB found that the captain's use of cocaine
degraded his performance and contributed to the accident (NTSB, 1989). For
on-demand (unscheduled) air taxi fatal accidents, the percentage of those pilots
tested that were positive for alcohol declined from 7.4 in the 1975 to 1981
period to 1.8 in the 1983 to 1988 period (NTSB, 1984 and NTSB, 1992).
An aviation success story in the United States is the effectiveness of the drug
testing program. Testing program results have shown a low rate of positive drug
tests in aviation from the beginning of the testing program, especially among
flight crews. In 1991, FAA statistics from drug tests conducted on 279,881
aviation employees and job applicants in safety and security-related positions
showed that 0.96 percent of the tests were positive for drugs of abuse. In 1992,
275,176 tests were conducted and 2,605 were positive, a rate of .95 percent.
These results include repair facilities workers, contractors, and airline
personnel and applicants. The positive rate for airline employees and applicants
remained about the same in 1991 (0.46 percent) as 1990 (0.40 percent).
Pre-employment tests accounted for 49 percent of the positive total in 1991 and
44 percent in 1992. Random tests of current employees accounted for the 46
percent of the positives in 1991 and 50 percent in 1992. Return to duty,
reasonable cause, and periodic tests, in that order, accounted for the remaining
positive tests in 1992. There were no positive post-accident tests in 1992 and
four in 1991. Positive results from random tests remained below 1 percent for
the third consecutive year. Flight crew accounted for 42 positive tests in 1991
and 32 in 1992. By far the largest number of positive tests
come from maintenance personnel (1,586 in 1991 and 1,598 in 1992).
Positive tests for both years indicated that marijuana was most prevalent (52
percent in 1991 and 57 percent in 1992), followed by cocaine (42 percent in 1991
and 33 percent in 1992), amphetamines (4 percent in 1991 and 4.7 percent in
1992), opiates (5 percent in 1991 and 4 percent in 1992), and PCP (1 percent in
1991 and 0.7 percent in 1992). Some persons tested positive for more than one
drug (DOT, 1992,1994). Clearly, progress has been
made and the aviation industry has now been permitted to reduce the random drug
test rate to 25 percent of covered employees.
RAILROAD
In 1972, the Safety Board recommended that the FRA, "...prohibit the use of
narcotics and intoxicants by employees for a specific period prior to their
reporting for duty and while they are on duty." Accidents in which alcohol and
other drugs were involved continued to occur. In 1987, the Safety Board
investigated a total of 156 selected accidents in which toxicological tests for
alcohol and/or drug use were available in 103 cases (88 under the FRA rule, 14
transit, and 1 other). In 29 of these accidents, 1 or
more railroad or rail/rapid transit employees used alcohol and/or drugs
(including prescription drugs) (NTSB, 1988a).
Perhaps the most serious railroad accident involving drugs or alcohol took place
at Chase, Maryland in January, 1987. A freight train improperly passed a stop
signal and entered a main line track and stopped. A passenger train travelling
at 120 miles per hour crashed into the freight train killing 15 passengers, the
engineer and injured 174 others. Both the freight train engineer and brakeman
were found to be heavy or frequent users of marijuana and were impaired by
marijuana at the time of the crash (NTSB, 1988b).
The results of the FRA's employee testing program showed significant reductions
when we last reported the 1991 results to you. I am pleased to report that the
trend of lower positive test rates has continued in 1992 and 1993. In mandatory
tests conducted on rail workers after accidents, 1.5 percent tested positive for
alcohol or other prohibited drugs in 1991, 2.1 percent in 1992 and 2.0 percent
in 1993. This is a substantial decrease from the 6.0 percent level in 1988. In
the reasonable cause tests, 2.1 percent were positive in 1991 and 1.9 percent
were positive in 1992 and 1993. This, too, is a substantial decrease from 5.4
percent in 1988. In 1990, random testing was introduced. In 1991, 0.9 percent
were found positive for drugs and by 1993 the random
drug test positive rate decreased to 0.7 percent (FRA, 1994). The railroad
industry has also been permitted to reduce its random drug test rate to 25
percent of covered employees.
COMMERCIAL TRUCKING
At T-92, we reported that drivers of heavy and medium trucks with positive BACs
are involved in about 750 fatal crashes each year, 7,700 injury crashes, and
4,750 property damage-only crashes (TRB, 1987). We also reported on the
Insurance Institute for Highway Safety roadside voluntary survey of truck
drivers in which 29 percent had evidence of drugs in their blood or urine.
Cannabinoids were found in 15 percent, nonprescription stimulants in 12 percent,
prescription stimulants in 5 percent, cocaine metabolites in 2 percent, and
alcohol in less than 1 percent. In 1992, we reported on a 1989 FHWA audit of
more than 143,000 truck driver drug tests. The overall positive test result rate
was 2.1 percent. By category of tests, 2.8 percent were positive on
pre-employment test, 0.8 percent positive on biennial tests and 14.2 percent
positive for reasonable cause tests. However, these results were not consistent
with the IIHS or the Safety Board's study.
In the Safety Board's study of fatally-injured truck drivers, we found that 33
percent of the drivers tested positive for one or more drugs of abuse. The most
prevalent drugs found were alcohol and marijuana (13 percent each), followed by
cocaine (9 percent), methamphetamines/amphetamines (7 percent), other stimulants
(8 percent), and other drugs at less than 1 percent. Forty one percent of those
drivers tested positive for drugs of abuse were found to be multiple drug users.
Almost 11 percent were positive for three or more drugs of abuse (NTSB, 1990b).
In that study, we recommended that the Federal Highway Administration conduct a
study of roadside drug and alcohol testing. The Omnibus Testing Act I referred
to earlier included a provision requiring that study
and results are now available.
A 1-year pilot study was conducted on interstate and major State roads in
Nebraska, Utah, Minnesota, and New Jersey. Only Nebraska and Utah could conduct
random, suspicionless drug and alcohol tests.
Minnesota and New Jersey conducted probable-cause based testing supplemented by
voluntary tests. The study found an overall positive test rate of 4.6 percent
for drugs and 0.20 percent for alcohol. The positive drug test rate was
substantially lower than the 29 percent found in the IIHS study. Both the IIHS
and FHWA studies found an alcohol positive test rate of less than 1 percent. The
test refusal rate was 4.2 percent for drugs and 1.0 percent for alcohol. The
refusal rate in this study was much lower than the 12 percent refusal rate in
the IIHS roadside testing study.
Marijuana was the most frequently identified drug, followed by cocaine,
amphetamines, opiates, and PCP. Rates varied markedly among the States with
amphetamine usage higher in Utah and cocaine usage highest in New Jersey. Study
data may be subject to interpretation because the reporting procedures included
both a medical review officer and a drug hierarchy in which some drugs were not
counted, for example in multiple drug cases. Further, the type of roadway and
truck included in the sample led the authors to believe that "the results
presented, understate the actual level of alcohol and drug use." (FHWA, 1995)
Nevertheless, this random roadside study provides the best data currently
available on the prevalence of alcohol and drug use by commercial truck drivers
in these States.
Approximately 7 million holders of a commercial
drivers license are now subject to alcohol and
other drug testing and the regulations now require test result reporting.
Therefore, I have great confidence that we will soon have even more
comprehensive data to report to you and that we can, as in aviation and rail,
report reductions in positive drug and alcohol test rates.
OTHER MODES OF TRANSPORTATION
The maritime industry was not included in the Omnibus Testing Act. We remain
concerned that the U.S. Coast Guard does not include uninspected fishing vessels
in its post-accident testing program. We note, however, that all merchant
mariners are now required to be tested for drug use when applying for new or
renewed licenses, certificates of registry, or other credentials. (Federal
Register, 1995) We look forward to better data reporting as well.
As I noted earlier, the crash of a subway train at Union Station in New York
sparked Congressional passage of the Omnibus Testing Act and granted specific
safety and testing authority to the Federal Transit Administration. Most of the
rail rapid transit systems in the U.S. have had some sort of alcohol/ drug
testing programs. A study of substance abuse in the transit industry showed that
drug and alcohol use was highest at transit agencies with limited or no testing
programs. We believe that the Omnibus Testing Act will help standardize and
improve the testing and prevention programs used by the industry.
CONCLUSIONS
I believe that the U.S. Federal Government has been exceptionally successful in
its drug testing programs and that at least one agency with a history of alcohol
testing has been very successful in reducing positive test rates. I have every
expectation that other transportation industries will achieve similar success
and that we will be able to document that success as fully as the rail and
aviation industries have done. Any attempts to further weaken our currently
successful programs should be very carefully considered.
I would like to note that the transportation workforce has a very low positive
drug test rate compared to the total workforce in the United States. A large
independent testing lab reported that less than 3 percent of transportation
workers in safety-sensitive positions tested positive for drugs in 1992 and 1993
while about 10 percent of the general workforce tested positive in these years.
(SKB, 1994) That said, there must be no tolerance,
absolutely zero, for alcohol and drug use in transportation. We have had great
success, but we are only half-way there. Obviously, testing alone will not solve
this problem. Testing does have a deterrent effect, but effective programs must
also include strategies to identify and treat abusers before it is too late.
