Event Summary
The accident occurred during a go-around when the rear engine failed. The pilot feathered the propeller. The landing gear remained extended and the flaps were set at one-third. The pilot reported hearing the stall warning multiple times. As the aircraft was not climbing, he initiated a left turn to avoid trees. The aircraft then stalled and struck the ground heavily on its main landing gear, subsequently flipping over.
Flight Details
The pilot reported that after the accident, he turned the fuel selectors to the off position. However, he stated that both selectors had been set to main during the flight and that the fuel tanks were topped off prior to departure. The total flight duration was approximately 1 hour and 35 minutes.
Post-Accident Examination
Examination revealed that all engine controls were in the forward position. The right wing fuel tanks were nearly full, while the left wing fuel tanks were empty. No evidence of fuel leakage from the left tanks was found. The right wing tanks normally supplied fuel to the rear engine, but in a cross-feed configuration, the left tanks could have provided fuel. If single-side fuel feed operations had been initiated with nearly full tanks, the side not being used would have been continuously refilling. No auto-feather system was installed.
Pilot's Handbook Guidance
According to the pilot's handbook, the procedure for a continued takeoff with an engine out includes throttles and propellers full forward, the inoperative engine feathered immediately, flaps retracted, and landing gear retracted after clearing immediate obstacles. The pilot had 224 hours of total flight time, with 96 hours in make and model, and 23 hours in the preceding 90 days.
