NTSB narrative
The accident airplane and three other airplanes were parked in a slightly staggered line and were being prepared for a cross-country group instructional flight. To stave off swarms of mosquitos while loading the airplanes, the engines of all four airplanes were started and allowed to operate at idle with the cockpits unattended. While the pilot was loading gear onto the right side of the accident airplane, the unoccupied airplane to the left of the accident airplane began slowly moving forward. The pilot attempted to go around the front of the accident airplane toward the left wing, likely to avoid the propeller of the moving airplane. Subsequently, the pilot was struck three times by the back of the accident airplane's spinning propeller.
Probable cause
The pilot's failure to ensure adequate clearance from the spinning propeller while traversing the area between the leading edge of the wing and the nose of the airplane. Contributing to the accident was the decision to leave the cockpits of the airplanes unattended while the engines were idling and gear was being loaded on board.

- 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.
