Accident Details
The pilot reported that shortly after takeoff, while climbing through approximately 700 feet MSL, the engine lost power without warning following a power reduction to 2500 RPM and 25 inches of manifold pressure. The pilot attempted to glide to an open field, but the aircraft impacted the tops of trees before reaching the intended landing area.
Examination
An examination of the engine revealed no preexisting failure or malfunction that would have caused the loss of power. Investigators did not identify any mechanical defects that could explain the power loss.
Fuel System
Both fuel tanks were ruptured during the impact, preventing determination of the pre-impact fuel quantity. Consequently, the possibility of fuel starvation or contamination could not be evaluated.
