On July 29, 2001, about 1000 eastern daylight time, a Cessna 152, N89803, registered to Friedman Aircraft Leasing, collided with a standing Beech 35-B33, N8660Q, registered to an individual, at Herlong Airport, Jacksonville, Florida. Both aircraft were being operated as 14 CFR Part 91 personal flights. Visual meteorological conditions prevailed at the time no flight plan was filed for N89803. An instrument flight plan was filed for N8660Q. Both airplanes received substantial damage. The commercial-rated pilot on N89803 and the private-rated pilot and two passengers on N8660Q were not injured. The flights were originating at the time of the accident. The pilot of N89803 stated that there was a comment on the time board for the airplane indicating the airplane had a magneto problem. He ran the engine in the airplane tie down area and the magnetos checked good. He had the engine power at idle and was putting on a headset when he must have released the brakes. The airplane moved across the ramp while he was looking down and collided with N8660Q. The pilot of N8660Q stated he was preparing for flight and was in the cockpit of his airplane. His two passengers were outside the airplane, behind the right wing. A Cessna, N89803, was parked across from him and he heard the engine of this airplane start up. He then caught sight of a wing coming at his windshield. The right wing of the Cessna contacted his stopped propeller blade and the spinner contacted his right wing and slid up his wing. The turning propeller of the Cessna then contacted his right wing's leading edge and the engine continued to run for 1 to 2 minutes. After the engine of the Cessna was shut down, one of his passengers pushed the Cessna away from his airplane to prevent a fire.
