Colorado City, Texas 79512
Wednesday, August 20, 2003 8:15 CDT

NTSB Narrative Summary Released at Completion of Accident

The 2,910-hour pilot reported that while maneuvering to return to a field he was performing aerial application on, the engine lost power. The pilot added that he saw three sets of power lines directly in front of his position and pitched up to avoid hitting them. As the airplane crossed over of the third set of power lines, "the airplane stalled" and impacted terrain in a "left wing and nose low" attitude. Examination of the engine revealed that the crankshaft was fractured at the cheek for the number two cylinder. A metallurgical examination of performed on the crankshaft revealed that a fracture initiated from at least two distinct origins in the fillet between the number 3 cheek and number 2 main journal, with beach marks throughout. The edge of the fractured surface was smeared. The reason for the failure of the crankshaft was undetermined.

NTSB Probable Cause Narrative

The loss of engine power due to failure of the crankshaft. A contributing factor was low altitude flight.
