Narrative:

While doing an overhead 360 I loaded aircraft too much resulting in a snap roll. Snap roll was stopped in the inverted position and a half slow roll brought the aircraft upright with little altitude loss. The cause was too much G load for the aircraft's speed but I feel my aerobatic and spin training avoided a stall spin accident. I feel requiring spin training and 10 hours of aerobatics would go a long way towards stopping many stall spin accidents.

Title: PLT IN OVERHEAD MANEUVER LOSES CTL RESULTING IN SNAP ROLL TO INVERTED.

Narrative: WHILE DOING AN OVERHEAD 360 I LOADED ACFT TOO MUCH RESULTING IN A SNAP ROLL. SNAP ROLL WAS STOPPED IN THE INVERTED POS AND A HALF SLOW ROLL BROUGHT THE ACFT UPRIGHT WITH LITTLE ALT LOSS. THE CAUSE WAS TOO MUCH G LOAD FOR THE ACFT'S SPD BUT I FEEL MY AEROBATIC AND SPIN TRAINING AVOIDED A STALL SPIN ACCIDENT. I FEEL REQUIRING SPIN TRAINING AND 10 HRS OF AEROBATICS WOULD GO A LONG WAY TOWARDS STOPPING MANY STALL SPIN ACCIDENTS.
