Analysis

Witnesses reported that they observed the acft perform two snap rolls. During the second snap roll something came off the aircraft and fell to the ground. The acft then became inverted and descended until impact with the ground. The acft impacted in a near vertical, nose low attitude in an open field. The acft canopy was found about 1/2 mi from the main wreckage. The list of operating limitatons attached to the airworthiness certificate for this acft states intentional aerobatic flight was prohibited.
