NTSB narrative
The annual inspection was overdue; the pilot had a ferry permit to fly the airplane to the place where the annual inspection was to be performed. With the assistance of a safety pilot on board the airplane which was tied down, he was unable to start the engine. He left the airport and obtained "starter fluid" but when he returned there was no person around to act as a safety pilot. He rechecked the rope used to tied down the airplane and found it secure. He was able to start the engine with the aid of the starter fluid and when near the pilot's side door, the rope broke. He grabbed the lift strut but was unable to stop the airplane which was going in circles; there was no assistance from individuals on the ground. He released the lift strut then some time later he grabbed the lift strut again and forced the airplane into trees.
Probable cause
The failure of the pilot to obtain the assistance of a person to act as a safety pilot while hand propping the engine with the airplane tied down. A factor in the accident was the failure of the tie down rope.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
