(.4) N69BM was discovered in a burnt out area, with two occupants in the wreckage. Subsequent investigation by the sheriff's office revealed that the pilot had been flying N69BM in formation with other aircraft, and had discontinued the return flight to practice aerobatics, and was reported missing by his wife after he did not return home. The medical examiner's office later verified the identities of the individuals who had been found in the wreckage, as those who had been reported missing by the pilot's wife. Postcrash examination of the burnt wreckage revealed that the airframe had incurred extensive damage consistent with hard ground impact, in an inverted position, and there were no indicators of any mechanical malfunctions to the aircraft or its systems. The propeller signatures found, were consistent with an engine producing power at impact. (-23)the aircraft came to rest inverted with the left wing s twisted and bent aft. And the fuselage streched and bent right at the wing root. The aft elevator control rod end and fwd. Rod end were found streched to the right and broken at the threads. The aircraft fabric and compsite prop blades were substantially damaged by post impact fire. The aircraft damage is consistent with other aircraft damage at the result of an inverted flat spin prior to impact.
