Colgan pilots fault airline's stall training
Updated: August 21, 2010, 9:21 AM
WASHINGTON — Colgan Air pilots said Thursday that the airline's inappropriate
training might have influenced Capt. Marvin Renslow's fatal decision to raise the nose of
Continental Connection Flight 3407, which then spun out of control and crashed to the ground,
killing 50 last February in Clarence.
Colgan's training emphasized maintaining a plane's altitude during a potential stall, four
pilots for the regional airline that operated the flight for Continental told The Buffalo
News. They said that contradicted what they previously had learned as pilots.
The four pilots, all speaking on condition of anonymity for fear of losing their jobs, said
Colgan taught pilots to react to stall warnings by maintaining altitude, even though safety
experts increasingly teach that the nose should be lowered and the altitude reduced slightly
to build the aircraft's speed.
Documents filed with the National Transportation Safety Board confirm the pilots'
contention. Most importantly, a Colgan training manual instructs pilots to "maintain
altitude."
Several safety experts said that was the wrong approach.
"Pitch up and maintaining altitude ... is contrary to what I was taught as an aviator,"
said Steven Chealander, a former military and American Airlines pilot who was the safety board
member dispatched to Buffalo at the time of the crash.
Chealander, who is no longer on the safety board, said he was speaking generally and did
not want to discuss the Colgan crash, because the probable cause of the accident will not be
revealed until the agency completes its work and releases its report in February.
"Negative training' But another source with knowledge of the
investigation said he expects that Colgan's "negative training" — essentially training
pilots to do the wrong thing — will be one of the factors cited in the agency's final
report on the crash.
Joe Williams, a spokesman for Colgan, said he could not respond to questions about the
airline's training until Monday. A spokesman for the Federal Aviation Administration also said
The News, which contacted the agency about this story at 2:11 p.m. Thursday, did not give the
agency adequate time to respond.
The Colgan pilots said the training policy — which the FAA had approved — has
since been reversed and that the airline's pilot training has vastly improved in recent
months.
But they also said the airline's poor stall recovery training in years past might have been
one of the factors that led to the crash in Clarence.
"Our training for this situation was a joke," one Colgan pilot said. "They stressed that
the way to recover from this sort of thing was to try not to lose altitude. That's all they
trained. ... What they told you to do is counter to what you're supposed to do."
The Colgan pilots stressed that several factors could have influenced Renslow's fatal
decision to pull back on the plane's yoke in order to raise its nose.
The safety board investigation found he had spent the evening before the flight in a crew
lounge at Newark Airport, meaning he could have been fatigued.
He also had been shown a training video on tail plane icing that might have led him to
believe that the plane was in a tail stall. Pulling back on the yoke would have been the
correct response in that situation.
Then again, the airline's emphasis on maintaining altitude to prevent a stall would have no
doubt been fresh in his mind, said the pilot who called Colgan's training "a joke."
"You're trained to pull back" on the yoke, that pilot said. "So what are you going to do in
that situation? You'll do what Marvin did."
The pilots interviewed stressed that their point of view was not just based on their
experiences, but also on documents filed with the safety board as it completes its
investigation of the Clarence crash.
The Air Line Pilots Association, in a recent submission to the safety board, said pilots
were told during training that they would need to "hold or increase pitch" — that is,
steady or raise the plane's nose — to pass their flight tests.
And a report filed by the safety board's operations group investigating the Clarence crash
also noted that sources it interviewed confirmed that Colgan's stall training focused on
maintaining altitude.
"It was stated in several interviews that during the stall recovery exercises for initial
simulator training, the candidates were instructed to maintain an assigned altitude and
complete the recovery procedures while not deviating more than 100 feet above or below the
assigned altitude," that report said.
Standard abandoned That goal stemmed in part from an FAA
edict that emphasized keeping the altitude steady when recovering from a stall, the operations
group said.
The FAA abandoned that standard in November 2008 and now emphasizes building speed as
central to stall recovery, said Capt. John Cox of Safety Operating Systems, a Washington,
D.C., consultancy.
The old standard "has been a problem in the industry for decades," Cox said. "There has
been a lot of discussion and an effort under way to get away from the zero altitude loss
philosophy."
The modern-day philosophy is that "you have to accept some altitude loss to get the plane
flying," Cox said.
That's because of the very nature of an aerodynamic stall, where the plane is flying so
slowly that its wings will not keep the plane aloft.
To build the speed needed to regain control, pilots not only must move the engines to full
power, but also must point the nose downward temporarily to allow gravity to give the plane a
boost in speed, aviation experts said.
"I can understand that the pilot does not want to lose altitude too fast, but at the same
time, you have to make sure the airplane has flying airspeed," said Scott T. Glaser of Defiant
Co., a California aviation consultancy that specializes in "upset recovery training," or
flying when things go wrong.
A former investigator for the safety board, meanwhile, stressed that other airlines
followed the FAA guidance and put too much emphasis on maintaining altitude.
"It does go against the way you are taught to recover from a stall in a small plane," he
said of pilots' early training.
In a true stall, he said, adding power alone will not be enough to recover control.
"You have to reduce the angle of attack," he said.
Asked if the training requirement could have contributed to the Colgan crash, the former
safety board investigator said, "You might say yes because they were not trained to positively
lower the nose, but no one ever was trained to pull up the nose the way (Renslow) did."
FAA also draws blame After the crash, Colgan's training
program was revamped to emphasize the importance of airspeed in stall recovery, the airline's
pilots said.
In addition, they said Colgan pilots now receive hands-on training in every element of the
stall recovery system, including the "stick pusher," an automated stall recovery devise that
Renslow overrode as he tried to control the plane on his own. Renslow never had such hands-on
training in that device.
While lauding the changes made by Colgan, another pilot for the airline blamed the outdated
training before the crash not only on the airline, but on the FAA, which must approve training
manuals and other elements of every airline's pilot training program.
"I have old training procedures [that] clearly state that the pilot must maintain altitude
while in a stall," that pilot said. "We objected to it several times, but it was not changed
until after the crash. The FAA was fully aware of this as they sat in our training events."
Another Colgan pilot said the airline's approach to training at the time did not focus on
ensuring that pilots knew how to react in case of trouble.
"It was all just about checking the box so it was done and accomplished," that pilot said.
A fourth pilot agreed, saying, "It doesn't do a good job in training you to deal with
real-world situations."
Told of all this, Mike Loftus, a former Continental Airlines pilot who lost his daughter,
Maddie, in the Clarence crash, said it's been clear for some time that the crew of Flight 3407
did not receive adequate training.
"I never really faulted Renslow or [First Officer Rebecca L.] Shaw for this," Loftus said.
"They were never trained or given the tools to do it the right way — and maybe they were
even led to do it the wrong way."
