What happened
Following a departure from runway 13, the aircraft was instructed to climb to an altitude of 6,000 feet. Approximately thirty seconds into the climb, the pilot reported experiencing engine difficulties and initiated a return to the airport. Shortly after this communication, the pilot notified air traffic control that the aircraft was unable to maintain its altitude.
While positioned one mile southeast of the airfield, the aircraft impacted the roofs of two residential homes. The descent continued as the plane struck two separate garages before hitting the ground and colliding with the rear portion of a third residence. The impact resulted in an intense post-crash fire. There was one fatality involving the pilot, who was the only person on board.
Findings
Investigations into the accident identified several mechanical failures contributing to the loss of control. The primary cause was a total failure of the engine's supercharger assembly, specifically involving the impeller. Additionally, a lack of lubrication within the engine system was noted as a factor.
During the emergency descent, the pilot attempted to feather the propeller; however, the propeller system failed to function correctly. The propeller remained pitched at an intermediate position between low and high RPM, and the movement of the feathering system was restricted. These mechanical malfunctions led to the total loss of engine power and the subsequent uncontrolled flight into residential structures.
