From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Between 6:30 and 6:40 pm witnesses observed aircraft performing aerobatic maneuvers. Last maneuver was a hammer head stall, vertical descent and the aircraft disappeared behind the terrain. Upon arrival the aircraft was inverted facing the opposite direction of travel 35 feet from initial impact point. Impact site was soft sand. Left main struck first making the rim oval in shape. Nose wheel was found in the same condition, both departed the aircraft upon striking. The right main was slightly damaged. The aircraft nose dug into the sand causing the aircraft to flip. Propeller was a three blade system with one blade broken off at the hub. A second blade was broken off approximately 4 inches from the tip and the third was cracked at about the same location of the second break. The propeller showed no signs of power being applied. Conformity of all flight controls were found to be intact. The throttle cable was found to be retracted to the idle position and bent from impact forces. Fuel tanks showed approximately 1 quart in each side. Fuel lines from the tanks to the carburetors had fuel in them. Both carburetors had fuel in them.
