Aircraft Accident/Incident Report

Flushing, New York 11371
Wednesday, August 14, 1996 19:20 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilots reported that shortly after takeoff, there was a compressor stall in the No. 2 engine, followed by a loss of engine power, and an abnormal oil pressure reading. The engine was shut down and the pilot made an emergency landing at JFK Airport. Debris came to rest in a residential area where a vehicle was struck. Examination of the engine revealed that turbine parts punctured through the turbine exhaust case in several locations but were contained by the fan exit duct. All the 4th stage turbine blades fractured across the airfoil just above the platform and were retained in the disk. Twelve of the twenty-five 4th stage turbine vane clusters were missing and the remaining clusters showed considerable trailing edge damage. All the 3rd stage turbine blades and vanes exhibited minor secondary damage with no blade or vane damage observed forward of the 3rd stage. The engine had accumulated 235 flight hours and 171 cycles prior to the incident since its last heavy maintenance inspection. The investigation did not reveal the exact origin of the turbine failure.

NTSB Probable Cause Narrative

a failure of the low pressure turbine assembly for undetermined reason(s).
