NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

Witnesses reported that the airplane was flying from north to south over the airport. One witness, who was an instructor and builder of the accident airplane make and model, observed the airplane "initiate a steep climb and then an approximate 60 degree bank turn." He described the bank as "non-sustainable, too much slide." Another witness reported that while maneuvering for the landing, the airplane entered a "hard left bank at low altitude and went into the ground." Witnesses reported the sky was clear and the wind was calm. Postaccident examination of the airplane revealed no anomalies with the airframe or engine. Toxicology test results were consistent with the recent use of diphenhydramine, a sedating and impairing over-the-counter antihistamine often known by the trade name of Benadryl. The extent to which impairment from the medication may have played a role in the accident could not be determined.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain control of the airplane while maneuvering.
