The pilot pulled the Cessna out of the hangar at the airport in Arlington, Washington. He told investigators he believed the airplane’s wheels were stuck in the snow.
During the engine warm-up, he had the seat all the way back and was checking the weather, as he planned to perform a 10-minute run-up. After five 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 hit a hangar.
The airplane sustained substantial damage to the left wing.
The pilot noted that the accident could have been prevented by keeping his feet on the brakes during the engine run-up.
Probable Cause: The pilot’s distraction during the engine warm-up, which resulted in the airplane’s collision with a hangar. Contributing to the accident was the pilot’s failure to set the brakes.
