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.

(-23) The pilot made the following statement: the accident occurred during an instructional flight on private property. After initial startup, all operational gauges were checked, all gauges were in the green. The governor was engaged and the student brought the helicopter to a 3 ft. hover. The helicopter hovered lefton my instructions, where there was an incline (slope). The helicopter made a 180 degree turn and must have moved backward catching the left skid and a sudden uncontrolled input on the cyclic caused the helicopter to bounce off the upslope skid. This input caused the helicopter to roll about the downslope skid exceeding the area of critical rollover, with the application of cyclic control. The dynamic rollover occurred in less than two seconds. On impact, all switches, mixture and ignition were turned off. An FAA inspector from the (cmh) FSDO inspected the aircraft at the accident site. Continuity of the flight and engine controls were verified. Fuel was present in the fuel tank.

As the FAA filed it

(-23) THE PILOT MADE THE FOLLOWING STATEMENT: THE ACCIDENT OCCURRED DURING AN INSTRUCTIONAL FLIGHT ON PRIVATE PROPERTY. AFTER INITIAL STARTUP, ALL OPERATIONAL GAUGES WERE CHECKED, ALL GAUGES WERE IN THE GREEN. THE GOVERNOR WAS ENGAGED AND THE STUDENT BROUGHT THE HELICOPTER TO A 3 FT. HOVER. THE HELICOPTER HOVERED LEFTON MY INSTRUCTIONS, WHERE THERE WAS AN INCLINE (SLOPE). THE HELICOPTER MADE A 180 DEGREE TURN AND MUST HAVE MOVED BACKWARD CATCHING THE LEFT SKID AND A SUDDEN UNCONTROLLED INPUT ON THE CYCLIC CAUSED THE HELICOPTER TO BOUNCE OFF THE UPSLOPE SKID. THIS INPUT CAUSED THE HELICOPTER TO ROLL ABOUT THE DOWNSLOPE SKID EXCEEDING THE AREA OF CRITICAL ROLLOVER, WITH THE APPLICATION OF CYCLIC CONTROL. THE DYNAMIC ROLLOVER OCCURRED IN LESS THAN TWO SECONDS. ON IMPACT, ALL SWITCHES, MIXTURE AND IGNITION WERE TURNED OFF. AN FAA INSPECTOR FROM THE (CMH) FSDO INSPECTED THE AIRCRAFT AT THE ACCIDENT SITE. CONTINUITY OF THE FLIGHT AND ENGINE CONTROLS WERE VERIFIED. FUEL WAS PRESENT IN THE FUEL TANK.
