March 19, 1999 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 |
Shouldn't that have read "Children Begin to [get] Inf[u]r[i]ate[d] [with] Airliners' First-Class Cabins"
[This message has been edited by Matt Wald (edited 03-22-99).] |
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? MF [This message has been edited by Merry (edited 03-22-99).] |
Why, merry, what ever do you mean?
(ahhhh, the magic of the edit feature!) |
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. |
The way I read the reports, "remember" is not in Matt's vocabulary.
|
That is a frightening story.

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

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! http://members.aol.com/ddmitchum/sylv_cat.gif CatMan http://members.aol.com/ddmitchum/sylv_cat.gif ------------------ [This message has been edited by Catman (edited 03-23-99).] |
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.

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)?????? |
