I received this Avweb Avflash yesterday, rather interesting...
"587 HEARING POLARIZES: The public hearing into the crash of an American
Airlines Airbus last November has degenerated into a polarized blamefest
over rudder deflection. There's now no argument that five full back-
and-forth deflections of the A300-600's rudder caused the tail to rip
off American Airline's Flight 587, precipitating its crash in New York
last November 12, which killed all 260 aboard and five on the ground.
Airbus maintains it told American Airlines that its training on use of
the rudder was faulty and indicated that communication implies the
carrier knew such a failure was possible. American denies Airbus ever
formally warned that moving the rudder too much at high speed could
cause it to come off."
