Analysis

Witnesses stated they observed the acft performing aerobatics while at an estimated alt of 1000 to 1300 ft. after the completion of a loop, the acft was observed to nearly come to a stop while vertical, then fall off to the left & enter a spin which continued until just prior to impact. None of the occupants wore parachutes as required by FAA regulations & a review of the pilot's flt logbook revealed no record of any aerobatic instruction. According to the acft manufacturer, loops & intentional spins are prohibited in this acft.
