NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

After takeoff, the flight proceeded to another airport where the pilot landed uneventfully and fueled at a self-service 100 low-lead (100LL) fuel pump. The airplane departed and proceeded towards the accident area where two witnesses on the ground reported hearing the engine sputter. One witness reported that the airplane flew low over his house with a rough-running engine. He additionally reported that the engine then lost power and the propeller stopped. The airplane pitched nose down indicative of a stall, then descended through tree before impacting the ground. A postaccident inspection of the engine revealed no evidence of preimpact mechanical failure or malfunction. Remnants of sealing compound from the wingtip tanks were found in the carburetor bowl but the discharge nozzle of the carburetor was not obstructed. Additionally, the fuel selector from the wingtip fuel tanks was noted to be faulty, allowing fuel to flow to the engine regardless of the position of the valve. No determination could be made as to the reason for the witness-reported loss of engine power.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot’s failure to maintain adequate airspeed following a loss of engine power for undetermined reasons.
