Aircraft Accident/Incident Report
San Juan
Tuesady, July 9, 1996 16:05 AST
NTSB Narrative Summary Released at Completion of Accident
The first officer was flying the airplane and after takeoff and flap retraction while manually retrimming the airplane, the elevator control system failed. The flight returned and landed uneventfully. Examination of the elevator control system revealed a failed cable segment between fuselage station 74 in the cockpit to fuselage station 310 in the cabin. The cable failed about midpoint between a 45-degree change in direction. Metallurgical examination of the failed cable revealed it failed due to fatigue and wear. The airplane manufacturer requires the cables to be inspected every 4,800 hours but the airplane operator reduced the time interval to 2,400 hours. The cables were last inspected 2,247.5 hours earlier. The airplane manufacturer requires cable replacement only on condition.
NTSB Probable Cause Narrative
Fatigue failure of a segment of the elevator trim control cable. Contributing to the accident was the failure of the airplane manufacturer to require a replacement interval of the cables.
