At 1100 eastern time, an American General AG5B struck a parked Beechcraft A90 King Air after the pilot hand-propped the engine at Michael J. Smith Field. The pilot and passenger received no injuries. The pilot said attempts to start the airplane were unsuccessful due to a low battery. He primed the engine and opened the throttle approximately a quarter inch and instructed his passenger to hold the brakes while he spun the prop. After the engine started, the airplane began to move and the pilot attempted to board the airplane but failed.
