An Aeronca, after landing on Runway 31L, taxied behind a Beech C-99 performing a runup. The Aeronca spun around and its engine quit. The pilot exited to hand-prop the engine, but the aircraft taxied unmanned and struck the Beech.

Event Details

A pilot had just landed an Aeronca aircraft on Runway 31L and exited at the first taxiway, receiving clearance from ground control to proceed to his destination on the airport. No request was made by the Aeronca pilot as he approached and passed behind a Beech C-99 that was executing a runup at a hold short location.

Sequence of Events

As the Aeronca passed behind the Beech, it spun around and its engine quit. The pilot of the Aeronca then radioed ground control, reporting that he had been spun around. In response, ground control requested the Beech to "come to idle," which the Beech pilot acknowledged. The Aeronca pilot then exited his aircraft to hand-prop the engine. Once the engine started, the aircraft began taxiing without any occupants, as the pilot had left the throttle in a position greater than idle. The Aeronca subsequently impacted the right rear quarter of the Beech.

Investigation Notes
