After liftoff, a false stall warning activated. The first officer transferred control to the captain, who landed the aircraft and applied maximum braking to avoid a runway barrier. All 292 occupants were evacuated; 10 were injured, one seriously.

Event Sequence

Immediately after liftoff, the stick shaker activated. The first officer, who was performing the takeoff, said "you got it." The captain then took control, closed the thrust levers, and landed the aircraft. He applied full reverse thrust and maximum braking, and turned the airplane off the runway to avoid a barrier at the end.

System Deficiency

A system design deficiency permitted a malfunctioning angle-of-attack (AOA) sensor to cause a false stall warning. The sensor had experienced nine previous malfunctions. It was inspected and returned to service without a determination on the reason for the intermittent malfunction.

Crew Response

The first officer incorrectly perceived that the airplane was stalling and gave control to the captain without proper coordination of the transfer of control.

Occupant Outcome

All 292 occupants were rescued. Among them, 10 were injured, one seriously.

Probable cause

Design deficiencies in the stall warning system that permitted a defect to go undetected, the failure of twa's maintenance program to correct a repetitive malfunction of the stall warning system, and inadequate crew coordination between the captain and first officer that resulted in their inappropriate response to a false stall warning.
