He exited the airplane and proceeded to rotate the propeller. When the engine started, it went to full rpm, and the airplane started to move forward on the taxiway at a high speed. The airplane veered off the taxiway and continued its high speed taxi until it impacted a hangar door, damaging the engine, both wings, and the right main landing gear. The pilot reported that he had not chocked the airplane and thought the brake was set. He further reported there were no mechanical problems with the airplane. ## Factual narrative The pilot stated that prior to starting the engine by manually rotating the propeller, he set the bakes, throttle, and trim.
