Analysis

Approximately 4 ft of the inboard section of the left wing separated in flight during an aerobatic maneuver. Witnesses stated that the acft had been performing little loops & then it went straight up & rolled off to the left upside down. It then spiralled once or twice, straightened out, made a slight right turn & then the wing failed. The latest operating limitations for the amateur built acft specifically prohibits any intentional aerobatic flt maneuvers.
