Incident Overview
An accident involving a Piper PA-24 occurred when the aircraft experienced a total loss of engine power during the initial climb phase immediately following takeoff. The pilot was forced to execute an emergency landing in response to the mechanical failure.
Mechanical Findings
Post-accident examination of the engine revealed that sand had penetrated into the cylinders. This foreign object debris prevented the valves and piston rings from seating correctly, which directly caused the loss of power. The presence of sand indicated significant contamination of the engine intake system prior to flight.
Contributing Factors
The aircraft had not been operated for thirty days prior to the accident flight. During this storage period, the airplane was parked facing into the wind without protective covers on the cowling or plugs in the air intakes. Records indicate that high winds and blowing sand were observed on two separate occasions during this time frame.
Pilot Error
The investigation determined that the pilot failed to conduct a proper preflight inspection before departing for the accident flight. This oversight allowed the contaminated engine to be started and flown, resulting in the in-flight power loss.
