Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

The pilot fueled the tail-wheel equipped Aeronca 11BC aircraft prior to a planned departure. The aircraft was not equipped with a parking brake, and the lack of an electric starter required hand propping to start the engine. The pilot secured the aircraft with a length of rope with one end connected at the aircraft's releasable tie-down tail hook, and the opposing end tied to a Chevron sign post. Initial attempts to start the aircraft with the throttle closed were unsuccessful, and the pilot then 'cracked' the throttle and hand propped the engine, which started immediately. The pilot reported that she 'saw the aircraft idling too fast and moving forward.' The rope then broke and the aircraft taxied into the metal barricades protecting the fuel pumps. The pilot reported that she carried chocks in the aircraft but had not used them at the time of the engine start.

NTSB Probable Cause Narrative

The pilot's failure to adequately secure the aircraft prior to a manual engine start. A contributing factor was the excessive throttle setting on start.
