Narrative:

Pushed the cub out of hangar and chocked the tailwheel of aircraft. Did a preflight on aircraft, no problems were found. I made sure the magnetos were off and the mixture was off. I pulled the propeller through a few times. Then, I proceeded to turn the magnetos on and the mixture on. I was by myself, so I made sure the tailwheel was still chocked, then I went and propped the engine to start. The aircraft started fine, but also jumped the chocked tailwheel. Aircraft turned to the right as the hangar stopped its movement. This pilot feels lucky not to be propeller meat, but my ego was severely bruised. In the future, I will either tie the aircraft down to a non moveable object or have help when starting the aircraft.

Title: J3-65C JUMPS CHOCK ON ENG STARTUP AT FFZ. ACFT AND BUILDING DAMAGED.

Narrative: PUSHED THE CUB OUT OF HANGAR AND CHOCKED THE TAILWHEEL OF ACFT. DID A PREFLT ON ACFT, NO PROBS WERE FOUND. I MADE SURE THE MAGNETOS WERE OFF AND THE MIXTURE WAS OFF. I PULLED THE PROP THROUGH A FEW TIMES. THEN, I PROCEEDED TO TURN THE MAGNETOS ON AND THE MIXTURE ON. I WAS BY MYSELF, SO I MADE SURE THE TAILWHEEL WAS STILL CHOCKED, THEN I WENT AND PROPPED THE ENG TO START. THE ACFT STARTED FINE, BUT ALSO JUMPED THE CHOCKED TAILWHEEL. ACFT TURNED TO THE R AS THE HANGAR STOPPED ITS MOVEMENT. THIS PLT FEELS LUCKY NOT TO BE PROP MEAT, BUT MY EGO WAS SEVERELY BRUISED. IN THE FUTURE, I WILL EITHER TIE THE ACFT DOWN TO A NON MOVEABLE OBJECT OR HAVE HELP WHEN STARTING THE ACFT.
