Cause of Flight 587 Crash in Queens Remains Unknown

Friday, 08 February 2002 12:00 AM

National Transportation Safety Board Chairman Marion Blakey said investigators were receiving data regularly about the Nov. 12 plane crash that killed 265 people when it slammed into several homes in Bell Harbor, a neighborhood in Queens.

Blake said investigators were analyzing video of the crash recorded from the ground and looking at other recent aviation accidents that might provide clues as to the cause of the November crash.

According to an NTSB statement, the plane's vertical stabilizer and rudder separated from the fuselage before impact.

The crash, the second deadliest in U.S. history, occurred just over two months after the Sept. 11 terror attacks that leveled New York's World Trade Center and damaged the Pentagon.

According to an NTSB statement, the federal agency is recommending additional pilot training regarding the use of vertical stabilizers during emergencies such as terrorist attacks and foul weather, as well as normal flying conditions.

Before Sept. 11, pilots and crew were ordered to comply with terrorist demands, though after the attacks pilots were given permission to execute evasive moves to thwart onboard terror attacks.

The NTSB is calling for training for 15,000 U.S. pilots flying commercial planes.

"What we really need to do ... is raise the awareness of all those involved," said Tom Haueter, deputy director of Aviation Safety.

However, the NTSB chairman emphasized that it has not determined the probable cause of the accident, be it pilot error or technical difficulties.

The plane - an A300-600 Airbus en route from New York's John F. Kennedy Airport to Santo Domingo, Dominican Republic - has become the subject of investigators' scrutiny due to the pre-crash separation.

The NTSB maintains that Flight 587 "twice experienced turbulence consistent with encountering wake vortices from a Boeing 747 that departed ahead of the accident aircraft."

The plane's flight data recorder recorded "several large rudder movements (and corresponding pedal movement) to full or nearly full available rudder deflection in one direction followed by full available rudder deflection in the opposite direction," says the statement.

After the radical shifting of the plane's rudder, the plane's recorder did not record "reliable rudder position data," a sign that investigators say is consistent with the separation of the vertical stabilizer from the rest of the plane.

Blakey said Friday that separation prompted the NTSB to issue warnings to the Federal Aviation Administration to take action and augment pilot training concerning rudder use.

Pilots use pedals on the cockpit floor to maneuver the plane's rudder.

NTSB statement says the board is concerned that pilots are not aware that radical rudder movements like those recorded on Flight 587, even at speeds below the designed maneuvering speed, "can dramatically increase the risk of structural failure of the vertical stabilizer rudder."

"We have seen several recent incidents ... that make it fairly apparent that this is not widely known by the industry and pilot community," according to Haueter.

Blakey said pilots might not know that on some airplanes even slight pedal movements can cause the plane's rudder to shift drastically.

"Rudder inputs by pilots (unfamiliar with the plane's controls) can cause catastrophic failure of its vertical stabilizers," she said.
