WASHINGTON - The co-pilot of American Airlines Flight 587 moved the plane's rudder back and forth, trying to control the climbing aircraft, not realizing he was sealing the grim fate of those on board. The National Transportation Safety Board (news - web sites) meets Tuesday to discuss its findings about the second-deadliest plane crash on U.S. soil.

First Officer Sten Molin was at the controls when the plane hit turbulence almost immediately after taking off from John F. Kennedy International Airport for the Dominican Republic on Nov. 12, 2001.

"Hang onto it, hang onto it," Capt. Edward States implored.

"Let's go for power, please," Molin said.

A second later came a loud bang, which investigators believe was the tail of the Airbus A300-600 breaking off. Then came the roar of air rushing against the aircraft and alarms sounding in the cockpit.

"What the hell are we into (inaudible)?" Molin said. "We're stuck in it."

States' last recorded words came five seconds later: "Get out of it! Get out of it!"

Both Airbus Industrie, which manufactured the jetliner, and American Airlines, which trained Molin, agree that if he had taken his foot off the rudder pedal, the tail wouldn't have broken off, the plane wouldn't have plunged into a New York City neighborhood and 265 people wouldn't have died.

But Molin didn't know he was putting more pressure on the tail than it could bear. Why he didn't — and who's to blame for that — is the subject of a bitter fight between Airbus and American.

According to investigators, Molin tried to steady the aircraft using pedals that control the rudder, a large flap on a plane's tail. When his initial movement failed, Molin tried again and again. His actions placed enormous stress on the tail.

American, the only U.S. airline to use that type of Airbus plane for passenger service, claims Airbus didn't alert it to the danger of sharp rudder movements until after the crash. The airline also contends the Airbus A300-600 has uniquely sensitive flight controls that can cause more severe rudder movements than the pilot intends.

"Airbus had the ability to truly red-flag the issue," American spokesman Bruce Hicks said.

Airbus says it told American a number of times and in a number of ways that the airline was improperly training pilots about how to use the rudder.

An Airbus spokesman declined to comment on the investigation before the hearing. However, the company has provided the NTSB (news - web sites) with a number of documents to support its claim.

For example, a letter dated Aug. 20, 1997, warned American chief pilot Cecil Ewing that rudders should not be moved abruptly to right a jetliner or when a plane is flown at a sharp angle. The letter was signed by representatives from The Boeing Co., the Federal Aviation Administration (news - web sites) and Airbus.


Airbus contends that even people within American Airlines were concerned about how the airline was training its pilots. A letter to Airbus dated May 22, 1997, from American technical pilot David Tribout expressed concern about the airline's then-new training course on advanced maneuvers.

"I am very concerned that one aspect of the course is inaccurate and potentially hazardous," Tribout wrote. His concern: Pilots were being taught that the rudder should be used to control a plane's rolling motion.

Hicks countered that Airbus didn't share important safety information about the rudder after a problem with American Flight 903 in May 1997. During that incident, pilots used the rudder to steady an Airbus A300-600 plane on approach to West Palm Beach airport. The plane nearly crashed and one person was seriously injured.

Afterward, Airbus told the NTSB that it included a warning that abrupt rudder movement in some circumstances "can lead to rapid loss of controlled flight," and, in others, could break off the tail.

Hicks said Airbus' comments didn't specifically say the rudder movements on Flight 903 had exposed the tail to so much pressure that it could have been ripped off.

Immediately after the Flight 903 incident, an inspection found no damage to the tail. But five years later, the plane was inspected more closely because of concerns aroused by the crash of Flight 587. Cracks were found and the tail was replaced.

John David, a spokesman for American Airlines' pilots union, said pilots had always thought that they could use rudders to the full extent without hurting the airplane. He also believes Airbus didn't properly communicate what it knew.

American now gives its pilots specialized training on the rudder control system based on information learned during the investigation.

Why was I thinking this crash happened on October 31? What famous crash recently happened on Oct 31? Egypt Air?

I recall that American Eagle ATR crash back in the 90s happening on Oct 31, and then I remember one or two others happening on Oct 31 too.

I think that ATR crashed because of its poor de-icing design in Indiana. The boots on the wing only broke off ice on the front of the wing and ice built up behind the de-icing equipment and disrupted the air flow of the wing the pilots had no chance to regain control.
