Aircraft Accident/Incident Report

Plainwell, Michigan 49080

NTSB Narrative Summary Released at Completion of Accident

Several witnesses reported observing the airplane shortly after takeoff flying and executing a number of turns. Prior to impact with terrain, the airplane "barely cleared the trees" and entered a steep left bank. The accident site revealed the left wing impacted terrain and the airplane came to rest upright. A postimpact fire consumed the airplane. Examination of airframe and engine revealed no anomalies that would have precluded normal operation prior to the accident. Each pilot had autopsy evidence of coronary artery disease and a previous heart attack, though it is possible that either or both were not aware of their heart disease. The pilot also had a history of a partial lung obstruction and glaucoma, neither of which appeared to have been causing symptoms or was likely to have affected his performance on the day of the accident. In addition, the pilot-rated passenger had recently ingested a medication containing an over-the-counter sedating antihistamine. The investigation, however, could not determine whether impairment or incapacitation affected either pilot.

NTSB Probable Cause Narrative

The pilot's failure to maintain aircraft control for undetermined reasons.
