During takeoff, the engine quit. After a bounced landing, partial power briefly returned then ceased. The airplane came to rest in a plowed field. Investigation found disabled wing drain petcocks, fuel system contamination, non-compliance with an AD, and inoperative gascolator drain.

Event Description

As the airplane was taking off, the engine quit. The pilot attempted to land on the remaining runway. The airplane touched down, bounced back into the air, and then floated over a road located at the end of the runway. While in the air a second time, the engine began to develop partial power for a few seconds and then quit again. The airplane subsequently came to rest in a plowed field.

Post-Accident Examination

Examination of the airplane revealed that all six wing drain petcocks were disabled. Contamination was observed in the wing tanks, gascolator, fuel lines, fuel distribution manifold, engine-driven fuel pump, and fuel filter.

Maintenance Findings

Research of the airplane records revealed that AD 87-11-01 R1, which was issued to preclude engine power loss due to either the accumulation of water or other contaminants in the fuel system, was not complied with. Further inspection revealed that the cable and release assembly that drains the gascolator was disassembled, rendering the quick drain inoperative. According to the airplane's logbooks, the most recent annual inspection was completed 23 months prior to the accident.
