Narrative:

The aircraft was an aeronca champ. The aircraft has no electrical system. I was hand-propping the engine. There was no way to tie the tail, so I chocked the wheels. The engine fired (the throttle was in idle position), and the plane came over the chocks. I tried to hold the plane by the strut, but I couldn't. I dove into the cabin and tried to hit the brakes but I was too late. The plane collided into a hangar. In the future, hand propping is a 2 person job. One in the cabin, holding the brakes. I would have preferred to tie the tail, but there was no way to do so.

Narrative: THE ACFT WAS AN AERONCA CHAMP. THE ACFT HAS NO ELECTRICAL SYS. I WAS HAND-PROPPING THE ENG. THERE WAS NO WAY TO TIE THE TAIL, SO I CHOCKED THE WHEELS. THE ENG FIRED (THE THROTTLE WAS IN IDLE POS), AND THE PLANE CAME OVER THE CHOCKS. I TRIED TO HOLD THE PLANE BY THE STRUT, BUT I COULDN'T. I DOVE INTO THE CABIN AND TRIED TO HIT THE BRAKES BUT I WAS TOO LATE. THE PLANE COLLIDED INTO A HANGAR. IN THE FUTURE, HAND PROPPING IS A 2 PERSON JOB. ONE IN THE CABIN, HOLDING THE BRAKES. I WOULD HAVE PREFERRED TO TIE THE TAIL, BUT THERE WAS NO WAY TO DO SO.
