Probable cause
Failure of the engine blower assembly drive shaft, while maneuvering at low altitude, and failure of the pilot to maintain adequate airspeed, which resulted in a stall before he could land.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot reported that as he was lining up to make his first swath run, the engine lost power. Also, he stated that as the aircraft was losing altitude and power, it got to about telephone pole height, then it stalled and collided with the terrain at a steep angle. A post accident exam of the engine revealed the supercharger shaft had sheared, which resulted in the loss power. Reportedly, the aircraft was fully loaded with fuel and dry fertilizer, when it crashed.
