Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The pilot's failure to properly secure the aircraft before hand-propping.

Analysis

Because of a low battery situation, the pilot elected to hand-prop the airplane. Once started, the aircraft rolled approximately 100 feet across the tarmac and collided with a hangar. The pilot was unable to gain access to the aircraft before it collided with the hangar. The aircraft's parking brake was not properly set and the wheels were not chocked.
