NTSB narrative
The pilot reported that he could not start the airplane's engine using the electric starter, so he elected to turn the propeller by hand to start the engine (hand-propping). He stated that when the engine started, the airplane's parking brake did not hold and that the airplane began to roll. He was unable to open the door to reduce the throttle setting, and the airplane subsequently struck a building. The airplane sustained substantial damage to the left wing, the fuselage structure near the firewall, and the engine mount structure.
Probable cause
The pilot’s did not properly secure the airplane prior to rotating the propeller by hand, resulting in inadvertent movement of the airplane and collision with a building.

Source notes (4)
- 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.
