This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A light aircraft was observed flying low over a cornfield before entering a descending right turn and impacting the ground. An autopsy revealed significant heart disease in the pilot.
What happened
The aircraft was engaged in a cross-country flight covering approximately 95 miles when it had traveled 16 miles into the journey. At this point, witnesses observed the aircraft flying at a very low altitude over a cornfield. The plane was estimated to be about 200 feet above ground level when it began a descending right turn with power applied. The aircraft continued this descent until it impacted the ground.
Findings
An investigation into the pilot's physical condition revealed significant health issues. An autopsy report disclosed that the pilot suffered from atherosclerotic coronary vascular disease, which was described as moderate to focally severe. This medical condition likely contributed to the loss of control during the low-altitude maneuver.
Safety message
Pilots must be aware of their physical fitness and manage known medical conditions to ensure they are fit to fly, particularly during critical phases of flight.
Probable cause
The pilot's inability to maintain aircraft control due to a medical event, specifically atherosclerotic coronary vascular disease.
