Narrative:
During takeoff, the Lockheed L-1011's left elevator became stuck in a fully upwards position, leading to the aircraft pitching up aggressively and causing the aircraft to lose speed and nearly stall. The pitching force, unable to be overcome by fully pushing the control column down, was counteracted by reducing the thrust on the L-1011's wing engines but not the tail engine. The differential thrust pitched down the nose of the airliner and allowed the pilots to land the aircraft.

- Probable Cause :
"The pressurization and depressurization of the L-1011 during flight cycles caused water to be pushed inside a bearing, heavily corroding it and causing the malfunction"
