United 747's Near Miss Initiates
A Widespread Review of Pilot Skills

By WILLIAM M. CARLEY
Staff Reporter of THE WALL STREET JOURNAL

As the United Airlines jumbo jet lifted off from San Francisco
International Airport one night last summer, one of its four engines lost
power. Because of poor flying techniques, the co-pilot who was at the
controls slowed and nearly stalled and crashed the plane.

"Push [the nose] down" to pick up speed, shouted two extra pilots sitting in
the rear of the cockpit. The co-pilot did, but now the jet was off course
and heading toward San Bruno Mountain northwest of the airport. The
jet's ground-proximity warning sounded, and the extra pilots shouted, "Pull
up, pull up!"

Carrying 307 passengers and crew,
the plane cleared the hill by only 100
feet. The jet also barely missed
apartments and houses with hundreds
of sleeping residents. A crash of the
jet, which was heavily loaded with
fuel, would have been one of the
worst aviation accidents in history.

The captain finally took control and
flew over the ocean, dumping fuel
before returning safely to the airport. But the incident -- just now being
publicly disclosed -- has rocked the world's biggest airline and spurred
the Federal Aviation Administration to force changes in United's
pilot-training techniques. The jumbo's low flight also has alarmed local
residents, with one man declaring in a call recorded by an airport hotline: "I
thought the **** thing was coming in on my roof."

United, a unit of UAL Corp., based near Chicago, acknowledges the
incident and says that it has spurred the carrier to take a series of steps,
ranging from a safety audit of all its 9,500 pilots to a major shakeup in its
pilot training. Edmund Soliday, vice president for safety, says the airline
hasn't lost a plane because of poor piloting for 20 years, "and we are
taking this incident very seriously." He says the airline aims to improve its
margin of safety "so we won't have to look at a hole in the ground
someday."

In Washington, Nicholas Lacey, who as FAA director of flight standards is
the agency's top official on piloting issues, says United's close call "didn't
result in a tragedy -- but it was a near-tragedy." Mr. Lacey adds that for a
variety of reasons, "complacency might have set in" among some United
pilots.

The agency is now pushing United hard to improve skills of its pilots,
especially its 747-400 co-pilots, or to ground some of them. One FAA
mandate that was to become effective this month would have grounded so
many United co-pilots that it would "severely hamper" the airline's
international operation, according to a letter to United pilots from the Air
Line Pilots Association. (The union represents the carrier's pilots.) That
FAA proposal has been modified, and United says international flights
won't be cut, but the agency is still pressing for pilot improvements.

Additional United close calls in recent months -- also never publicly
disclosed -- have broadened the concern beyond the 747-400 crews. "In
the past months, we have had several operational incidents," airline jargon
for close calls, W.J. Carter, chief of United's Honolulu-based pilots, wrote
in a Feb. 23 internal memo to his flight crews. "Major accidents historically
are preceded by a series of these seemingly unrelated incidents. This
disturbing trend is cause for concern," the memo continued.

United has set up a special one-hour safety seminar which all its pilots
must attend by May 10. If they don't, they will be dropped from the flying
schedule without pay. According to the union's letter to United pilots,
"This is as close as an airline can come to a military 'stand down,' " when
military flyers are temporarily grounded because of safety concerns.

United officials declined to discuss details of the incidents because they
were disclosed to management by pilots under a confidential
safety-reporting system. But many safety analysts say that United, which
had no legal obligation to publicly disclose some of the close calls, should
be commended for alerting its pilots. "They have treated this [San
Francisco] incident like an accident to raise safety awareness among their
pilots, and for that I give them kudos," says the FAA's Mr. Lacey.

Despite the close calls, United emphasizes its safety record is excellent,
with nearly 6.2 million flights without a crash since a United 737 went
down in Colorado Springs in 1991. Safety analysts agree that United's
record is strong. United has been a leader in many safety measures,
including teaching pilots in simulators how to escape wind shears, beginning
in the 1980s, and installing better ground-proximity warning systems in jets
in recent years.

The close call in San Francisco, safety analysts say, raises issues that have
been worrisome for years. Airplanes are designed to take off and climb
safely even if an engine fails. In the San Francisco episode, why didn't the
United co-pilot fly the plane properly? There is "no doubt we had a pilot
proficiency problem," concedes United's Mr. Soliday.

One factor in pilot proficiency is the enormous increase in long-range flying
in recent years. The jet in the close call was a Boeing 747-400, designed
to fly nonstop trips such as New York to Tokyo. The jumbo routinely
makes 14-hour flights. Concerned about pilot fatigue, Boeing designed the
cockpit for as many as four crew members: a captain and co-pilot who
handle flying duties, and two extra pilots sitting behind (dubbed "bunkies"
because they can rest in bunks) who relieve the others during the flight.

But because these flights and rest periods required between them are so
time-consuming, pilots make only a few trips each month. And with four
pilots aboard, chances of practicing takeoffs and landings -- the most
critical phases of flight -- are few.

At United, says a spokesman, captains of 747-400s average only three
takeoffs and landings a month. Co-pilots, because there are three of them
aboard each flight, get even less practice, averaging just one takeoff and
landing a month. Because of scheduling complexities and vacations, some
co-pilots don't make a takeoff and landing for months.

The problem isn't unique to United. Boeing has sold nearly 450 of the
747-400s to 30 airlines around the world, including British Airways,
Japan Airlines and Northwest Airlines. Nor is the issue confined to
Boeing planes; the Airbus Industrie A340 makes similar long flights, many
with four pilots in the cockpit.

How many jets at other carriers may have had narrow escapes similar to
United's isn't known. Because of limitations and loopholes in FAA and
National Transportation Safety Board databases, many close calls escape
public notice. But David Simmon, a former United pilot who is now a
safety consultant, says long-range flying "is known to cause proficiency
problems due to the limited number of takeoffs and landings shared among
a four-person crew." The issue, he adds, "is an ongoing industry problem."

Another factor in the San Francisco close call may be complacency. The
latest generation of jets, including the 747-400, are so highly automated
and reliable that pilots may simply get bored. "On these long flights, it's
very hard to keep the pilots on the edge of their seats," says Cecil Ewell,
chief pilot and vice president for flight at American Airlines. "Hardly
anything ever goes wrong," says the FAA's Mr. Lacey.

The answer to these concerns was supposed to be simulators, where pilots
can drill regularly and practice emergency moves. But the simulators can't
replicate everything, and still can't replicate critical moments in United's
close call. There are also questions about how well simulators are used for
training. Asks Mr. Simmon, the consultant: "Is some simulator training
perfunctory?"

Such problems may have played a role last June 28 as United Flight 863
prepared for takeoff at San Francisco International. FAA documents and
tapes of air-traffic controllers obtained by The Wall Street Journal under
the Freedom of Information Act, as well as interviews with pilots familiar
with the incident, show the takeoff wasn't going to be routine.

Bound for Sydney, Australia, the jet weighed almost 450,000 pounds and
was carrying nearly an additional 400,000 pounds of fuel for the long flight
-- weight that would reduce its ability to climb. And as the jet revved its
engines at 11:39 p.m., ocean fog had crept in, obscuring much of the San
Francisco area -- including the hills northwest of the airport.

"United 863 ... , runway 28 right, cleared for takeoff," the San Francisco
tower controller radioed to the plane.

For reasons that remain unexplained, the co-pilot at the controls had even
less real-world practice than usual. He had made a takeoff and landing in a
real 747-400 the previous week, but that was his first in nearly a year.
(FAA rules call for three takeoffs and landings within 90 days, but all can
be done in a simulator.)

Just as the jet lifted off from the runway heading northwest, the right
inboard engine malfunctioned for unknown reasons, triggering so-called
compressor stalls in the engine. These stalls produce enormous backfires,
with fire and smoke exploding out the rear of the engine and violently
shaking the whole plane.

"It's bang, bang, bang and shudder, shudder, shudder," says the FAA's
Mr. Lacey.

The shaking was so violent that the pilots couldn't read their instruments at
first, and frantically guessed at the cause. "Maybe it's a [blown] tire," one
of the extra co-pilots shouted. But then the co-pilot at the controls read an
instrument showing problems in the right inboard engine, and it was shut
down.

With two engines at full power on the left wing and only one now operating
on the right, the left engines began pushing the plane into a right turn. To
counter that, pilots say, the co-pilot should have just used the rudder on the
tail. But he mistakenly turned his control wheel to the left. That extended
ailerons, control panels on the rear of the wings which would tend to make
the jet bank to the left. But the co-pilot's action also extended spoilers,
panels on top of the wing that increase drag and cut the jet's ability to
climb.

Unable to climb much, but with its nose still up, the heavy jet began to slow
down, so much that the dreaded "stick-shaker" warning began. In this
warning, the pilot's control column literally shakes, signaling the plane is
going so slow that it's beginning to stall and is about to crash.

"Push down, push down" the nose to gain speed, the extra co-pilots yelled.
The co-pilot did, but now there was another danger ahead. Off course
because of the right turn, the jet was headed towards San Bruno mountain,
a broad lump that rises to 1,576 feet a few miles northwest of the airport.
Densely populated areas lap at the mountain's base. The crew couldn't see
the mountain. It was bathed in dense fog.

Suddenly the plane's ground proximity warning sounded, an automatic
voice calling, "terrain, terrain, pull up, pull up." The two extra co-pilots
echoed the warning, screaming "Pull up!"

Heavy with fuel, spoilers extended and still in a skidding right turn which
further increased drag, the jet could barely climb. But the co-pilot pulled
the nose up anyway. The jet cleared the top of the mountain by about 100
feet, according to both airline and FAA officials. It was so close to the
ground that air controllers' radar lost contact with the plane, sparking fears
in the tower that Flight 863 had crashed.

San Francisco controller Cynthia Grimm immediately called a controller at
another FAA radar post. "Hi, is United 863 -- oh, there he is" on the
radar scope, she exclaimed. "He scared me, we lost radar" contact.

Lurching over South San Francisco, then Daly City and San Francisco, the
jet was so low it terrified residents. At the airport, a telephone hot line
recorded a deluge of complaints. "People were running out of their houses
for fear the plane was going to crash," a South San Francisco resident said,
according to call transcripts. The identities of callers are kept confidential.
The jet set off car alarms, "it shook the whole house, we thought it was
going to take out the neighborhood," said another caller.

In Daly City, "I thought I was going to have to go under the couch," one
man said. And a San Francisco woman said her daughter's nearby home
was shaken "like it was an earthquake."

As the jet headed out to sea to dump fuel for an emergency landing, the
FAA was already securing tapes of the air controller conversations.
United officials retrieved the jet's flight-data recorder, which saves items
such as speed, altitude and engine performance, and began their own
inquiry.

FAA and United officials were shocked at what they found: The crew had
violated fundamental flying rules, such as maintaining minimum air speed.
"They didn't do the basics," says the FAA's Mr. Lacey.

The FAA, United and its pilots' union have taken a series of remedial
steps, some short-term "quick fixes," as one United pilot puts it. They have
also launched studies which in the next year or so may lead to other
changes in United's operations.

One of the more controversial moves was made in December by James
Edwards, the FAA's principal operations inspector overseeing United's
pilots. He ruled that by this month, every 747-400 co-pilot had to have
made three takeoffs and landings in a real plane within 90 days or be
effectively banned from the cockpit. That would have grounded so many
co-pilots that United would have been forced to cancel some of its
overseas flights, including as many as 30% of its Pacific flights, according
to a pilots' union estimate.

But the FAA and United have hammered out a compromise. Within 90
days of a flight, a co-pilot now must have made at least one takeoff and
landing in a real jet, plus two in a simulator. Co-pilots who haven't met the
requirement must make their next flight with a "check captain." Check
captains are highly experienced management pilots who check other pilots.

"The bottom line," states the Feb. 3 union letter to all United pilots, "is the
FAA, after reviewing our aircraft landing records and other items, has
determined that the simulator cannot nor was it ever intended to be the sole
method" for keeping pilots' landing skills up to date.

United has taken other short-term steps. It has retrained the crew of Flight
863. Using data from the recorder and with other pilots playing the role of
the crew, the airline made a video portraying the close call in one of its
simulators at its Denver training base. The shaking of the real airplane,
however, was so severe it couldn't be duplicated in the simulator. United is
now trying to improve its simulators.

The carrier is showing the video to all its pilots, and re-emphasizing certain
flying rules. One rule: the rudder (not ailerons) must be used to maintain
direction when an engine fails on takeoff.

In addition, United has increased the frequency of recurrent training for all
its 747-400 pilots. Instead of getting recurrent training -- which involves
days of extensive simulator and classroom work -- once a year, 747-400
crews are now getting it twice a year.

United has spent $2.5 million on remedial measures, and "before we're
through we may be up to $5 million," says Mr. Soliday.

United and the pilots' union also have set up a joint committee composed
of 10 747-400 captains and co-pilots to study possible changes in how the
jet should be manned. At Northwest Airlines, for example, a 747-400
cockpit features a captain and co-pilot at the controls, and a second
captain and co-pilot in the seats behind who provide relief on long flights.
At United, there is only one captain and three co-pilots, called first
officers. Captains are generally more experienced than first officers.

William Brashear, a United 747-400 captain and pilots' union official, says
the Northwest system will be one of the approaches studied. But he says
that at United, all the co-pilots are trained and rated as captains anyway,
and lack only seniority to get the captain's title.

In the meantime, says Mr. Brashear, United and its pilots "are working just
as hard as we can to make this airline as safe as possible."

another sign that there are many lurkers on this board...

A short six sentence report on 3/19 WSJ by DANIELLE REED is titled: "Children Begin to Infiltrate Airliners' First-Class Cabins"

Sound familiar? http://www.flyertalk.com/forum/smile.gif

Matt: If you are going to get a gramma head on, you have either inflitrated or you have not. You can't begin to infiltrate. That would be like being a little dead. http://www.flyertalk.com/forum/smile.gif

How will the children ever learn?

Matt, he was trying to set me on you earlier, but I held back.

Just remember the cautionary tale from Saturday night... Mr Merry is someone on whose good side it is good to stay.

I know! Those children in first class!

I kid. As someone who has flown and will fly on one of those SFO 747-400's, I was quite concerned at the fact that UA's pilots have so little actual experience in take offs and landings.

JAWS_II Mar 22, 1999 4:04 pm

PremEX has all the experience at landings and he is not even a pilot, JUST a 1K!!!!

Catman Mar 22, 1999 11:49 pm

I want to say something about going off topic but the cat got my tongue and I don't want to be labeled as "TOO CRITICAL."

But this board has been fun reading!

It's scary. Makes me want to stop flying UA (which I seldom do anyway), just like the stories about 737 crashes make me want to stop flying 737's (which I pretty much have to do because they're the most ubiquitous thing in the air). Point: We fly because we have to - sometimes because we want to - and we pays our money and we takes our chances.

kokonutz Mar 25, 1999 6:39 am

Emotionally, statistically and instinctually, I feel (and am) safer in an just about any airplane than in the back of a taxi.

Number of times I felt like my life was in peril on an airplane: 1.

Number of times I felt like my life was in peril (seriously) in a NYC taxi: COUNTLESS.

I'm glad UA is being proactive, but why is it that stories like this rock people to their core, when every single night driving home from work, one hears on the traffic report about a fatal car wreck, and that has no more effect on us than the news that the Dow dropped six points in light trading (unless, of course, the wreck makes us late for dinner)??????
