If an airliner can't handle .4 to .8 G laterally across the tail, how did it get certified as airworthy? Either this was sabotage, or I'm never going to fly on an Airbus product again.

Some sort of minor weakness in the tail was probably exacerbated by the relative wind passing over the tail section. If the weakness results in oscillations driven by the wind, the structure could weaken quickly and suffer catastrophic failure. The phenomenon is known as flutter. Flutter of the elevator control surface is what led to the crash of the Alaska Airlines jet a couple years ago off southern California. The structural weakness that allowed the oscillations need not be exactly where the break occurred.

Considering how carefully calculated the destruction of the World Trade Center was, it's not unreasonable to think that the terrorists devised other equally skilled ways of destroying airplanes. I'm convinced that there are terrorist cells in the NYC area. I've read the government version of what caused the crash of TWA 800 and also the alternative versions. I lean toward terrorists shooting down TWA 800. The US Government has a history of covering up the causes of airline accidents going back to KAL 007.

Isn't it funny that the anthrax attacks are winding down. Wasn't there a story about some muslims carrying mail in plastic bags to their car in the middle of the night in New Jersey? They were picked up by the FBI, and the anthrax attacks have stopped. But the latest government spin is that a lone middle aged American male is responsible. I guess this is more palatable to the American public.

This is the first time a modern airliner has broken up in the air, other than bombings or excessive speeds.

Carl,

That depends on what you mean by "breaking up."

It's certainly not the first time an airliner has crashed due to catastrophic control surface or engine separation.

In 1979 the nation's entire fleet of DC-10's was grounded because of this crash:

vtvt.essortment.com

"On May 25, 1979 an American Airlines DC-10 took off from the Chicago International Airport at O'Hare Field. The plane reached a height of approximately 400 feet before losing its left side engine. The resulting crash killed everyone on board the plane and two persons on the ground. It was, and remains to this day, the worst air disaster in United States history....

"An official NTSB report, when discussing the cause of the crash, read as follows:

"...contributing to the cause of the accident were the vulnerability of the design of the pylon attach points to maintenance damage; the vulnerability of the design of the leading edge slat system to the damage which produced asymmetry; deficiencies in Federal Aviation Administration surveillance and reporting systems which failed to detect the use of improper maintenance procedures; deficiencies in the practices and communications among operators, the manufacturer, and the FAA which failed to determine or disseminate the particulars regarding previous maintenance damage incidents; and the intolerance of prescribed operational procedures to this unique emergency."

It's not unlikely that the NTSB will find that some kind of undetected fatigue or maintenance failure was a contributing factor in the JFK crash, perhaps exacerbated by the encounter with the wake turbulence of the 747 ahead of the A300.

Message 16666756

If so, EVERY A300 in the world should be grounded and inspected, and maintenance procedures remedied.

Cheers and happy flying,

Climber
