Accident Sequence

According to witness accounts, the airplane was observed overflying homes at low altitude in a tight circular pattern. One witness, located about half a mile from the airport, reported watching the plane attempt a left turn to return to Highland County Airport. The witness stated that the plane made a sharp turn and seemed to have difficulty stabilizing.

Another witness reported hearing a loud noise and then seeing the airplane just above the trees with its landing gear extended. The airplane "kept dipping up and down." A further witness noted the airplane "wobbling left to right" before it descended into trees, struck vehicles, and came to rest against a tree. A post-crash fire destroyed the airplane.

Witness Observations

Multiple witnesses provided consistent descriptions of the airplane's erratic flight path. The aircraft was seen at low altitude, maneuvering tightly, and exhibiting instability during turns. The landing gear was observed to be down throughout the final moments of flight.

Pilot Background

A person who had flown with the pilot as a safety pilot on several occasions reported that the pilot had a habit of making steep close-in turns from downwind to base to final. The safety pilot also noted a "lack in airspeed management during approach."

Wreckage Examination

Examination of the wreckage did not disclose any preimpact failure of the airplane or engine. The airframe and engine were found to be intact prior to impact.

Probable Cause

The official probable cause of the accident was the failure of the pilot to maintain adequate airspeed while maneuvering, which resulted in an inadvertent stall and collision with trees, vehicles, and the terrain.
