| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that after an aerial application run of approximately 30 minutes the aircraft departed the spray-run in a climbing right turn when the engine, '...burped once or twice and quit.' The pilot reported that the terrain around his position was heavily wooded except for a narrow swamp area in which he elected to land the aircraft. During the on-scene portion of the investigation, the engine and its components were examined. Partial disassembly of the P&W R-1340-AN1 engine disclosed that the blower impeller had failed which would have restricted induction air to the cylinders.
Probable Cause: the compressor impeller failure and the unsuitable terrain for landing encountered by the pilot.
