Sequence of Events
The pilot signaled the ground marshaller to disconnect ground power and remove chocks after a normal start of the No. 2 engine. The ground marshaller disconnected the power cord and secured it to the ground power cart. As she pulled the nose wheel chocks, the nose tire ran over her foot.
The airplane then taxied forward, and the No. 2 propeller collided with the ground power cart. The impact ignited a fire in the No. 2 engine, which spread to the ground and under the aircraft.
Evacuation and Response
Without any communications from the cockpit, the flight attendant commanded a passenger emergency evacuation. During the evacuation, three passengers received minor injuries from tripping and falling on the tarmac.
Fire Suppression
The airport fire department arrived and extinguished the fire three minutes after its initiation.
