Aircraft Accident/Incident Report

Donnelly, Minnesota 56235
Sunday, July 6, 1997 20:00 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot said that he was in a turn to line up on the field he was about to spray when the 'number 9 cylinder blew.' The pilot turned towards a road which he intended to use for landing the airplane on. On approaching the road he 'noticed a person on the road.' The pilot abandoned the attempt to land on that road and began to maneuver for a landing on a perpendicularly intersecting road. As he was maneuvering, the 'engine failed completely.' The pilot put the airplane down in the field. During the landing roll, one main landing gear leg broke. The airplane nosed over coming to rest inverted in the field. Examination of the airplane revealed a large amount of oil covering the airplane's exterior. Examination of the airplane's engine revealed the number nine cylinder broken into three pieces. The number nine cylinder connecting rod was also broken. No other anomalies were found with the airplane.

NTSB Probable Cause Narrative
