Aeronca 11AC N86078 accident near Frankenmuth, Michigan

Probable cause

The pilot's loss of control for undetermined reasons based on available information.

NTSB analysis

The pilot and passenger were on a local pleasure flight in a single-engine airplane. A witness reported that the pilot was doing touch-and-go landings. The wind was calm, so the pilot departed to the east and then returned to land to the west. The witness did not see the crash but heard the impact and then saw smoke. The airplane impacted a cornfield about 1/4 mile east of the airport. A postcrash fire consumed or thermally damaged the majority of the airplane. The fire and impact damage limited the scope of the examination; however, no evidence of pre-impact abnormalities was noted with the engine or airframe. The pilot's autopsy and toxicology testing found no evidence of any medical condition or medication use that would have impaired his performance, and he had favorable weather conditions for the flight. The accident was consistent with the pilot's loss of control for undetermined reasons.
