The momentary operation of the airplane outside of the airplane's aerodynamic design stall buffet boundary that resulted from the captain's initiation of a Ground Proximity Warning System (GPWS) escape maneuver. Factor's contributing to the accident were the false readings of both radio altimeters which prompted the false GPWS warning, and the inadequate structural capability of the elevator design to remain intact during momentary operations outside of the stall buffet boundary.
