A pilot lost control of an aircraft while attempting to stop it after a passenger ejected from the jump seat during taxi, resulting in a nose-over crash into a field.

What happened

The pilot in command attempted to start the engine using a low-battery power source. To overcome compression resistance, the pilot exited the cockpit and manually rotated the propeller one-quarter of a turn. Once the engine started with a passenger aboard, the aircraft proceeded to taxi. The pilot was unable to bring the aircraft to a stop. In response, the passenger attempted to intervene but ultimately opened the door and ejected from the aircraft. The unmanned aircraft continued forward for approximately half a mile before entering a soft farm field and nosing over.

Findings

The incident involved a single fatality resulting from the uncontrolled ground movement. The primary causal factor was the pilot's inability to stop the aircraft after the passenger's ejection, compounded by the initial difficulty in starting the engine due to battery issues.

Probable cause

The pilot's failure to maintain control of the aircraft during taxi, which resulted in the passenger ejecting from the jump seat and the subsequent uncontrolled movement of the aircraft into a field.
