Aircraft; Human Factors; Procedure
I rented the aircraft from the owner for an approximately 1-hour local VFR flight. A non-pilot passenger was invited to ride in the front seat for the flight. The airplane was placed on the taxiway in front of the hangar where it normally stays; and was facing northwest for the engine start. The plan was to start the engine; taxi to the fuel pumps; shut down; and top off the fuel tank. After fueling; I planned to start the aircraft and taxi to Runway XX to depart on the local VFR flight. The aircraft has no starter and a hand-prop was utilized. I was the person that hand-propped the aircraft. After hand-propping; the aircraft accelerated away and to the right; impacting the hangar door. Neither the passenger nor I were injured. Best solution is to always have the PIC in the aircraft and have a second person hand prop. In lieu of this; having substantial chocks in place would be the next best option.
