Aircraft Accident/Incident Report

Cochran, Georgia 31014
Wednesday, July 17, 2002 8:00 EDT

NTSB Narrative Summary Released at Completion of Accident

After about 45 minutes of aerial application to cotton crops, following the third pass on his second field, the pilot reported his engine started backfiring and shaking violently. He started for his home field, but could not sustain level flight. He chose a cotton field for an emergency landing, but his right wing struck a tree causing damage to the wing and main landing gear. Post crash examination of the engine revealed a broken magneto housing, causing defective ignition timing.

NTSB Probable Cause Narrative

A loss of power while conducting aerial application to cotton crops due to failure of a magneto housing, and the resultant emergency descent and landing to an unsuitable field, causing the collision with a tree.
