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.

Witnesses noticed the aircraft north east of the airfield doing aerobatic maneuvers. The witnesses stated that the aircraft completed a loop and entered an inverted flat spin of which the pilot regained control. The aircraft then gained altitude and the pilot turned on the smoke system and continued a loop. The aircraft again went inverted and into what appeared to be a flat spin. The engine could be heard running during the descent and to the point of impact.

The crash scene is located on the north side of a hill and the aircraft hit nose first and rolled the engine under the front of the airplane into the cockpit. We found no apparent continuity issues, all controls are connected. The carburetor float bowl is void of fuel. The engine was completely disconnected from the airframe. The propeller is a two blade type and one blade had no damage the other was bent aft with no twisting.

All maintenance inspections are current.

The aircraft sustained substantial damage.
