After 5 minutes, he noticed that the engine rpm increased from 800 to 1,200. He recalled that when he noticed the increase in engine rpm, he was about to adjust the throttle, but the airplane began to roll and collided with a hangar. The pilot added that the accident could have been prevented by keeping his feet on the brakes during the engine warm-up. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that he had pulled the airplane out of the hangar, and that he believed that the airplane's wheels were stuck in the snow.
