NTSB narrative
WHEN THE PILOT ATTEMPTED TO START THE AIRPLANE HE FOUND THAT IT HAD A DEAD BATTERY. HE THEN INSTRUCTED THE NON-RATED PASSENGER ON HOW TO MANIPULATE THE ENGINE CONTROLS AND PROCEEDED TO HAND PROP THE ENGINE. THE ENGINE STARTED AT FULL THROTTLE AND THE PILOT WAS UNABLE TO BOARD THE AIRPLANE AS THE PASSENGER WAS BLOCKING THE ENTRY IN HIS ATTEMPT TO GET OUT. THE AIRPLANE SUBSEQUENTLY ROLLED ACROSS A RUNWAY, THROUGH THE AIRPORT BOUNDARY FENCE, THROUGH A DITCH, AND ACROSS A ROAD INTO AN OPEN FIELD BEFORE THE NOSE GEAR COLLAPSED AND IT NOSED OVER. NO CHOCKS WERE USED DURING THE START.
Probable cause
THE PILOT'S USE OF IMPROPER STARTING PROCEDURES WHICH RESULTED IN THE LOSS OF CONTROL OF THE AIRPLANE. A FACTOR IN THE ACCIDENT WAS THE AIRPLANE'S ENCOUNTER WITH ROUGH TERRAIN DURING THE UNMANNED TAXI.

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. 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.
- API snapshot SHA-256: f1d576a2c7b2ac36eabfef186b4ad074817bf1de8e2b64636a424300109ad6b6; retrieved 2026-09-23T04:59:56.851Z.
