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) At approx. 1410 local CST, N2301C, a Robinson R-22 helicopter crashed while practicing simulated engine out procedures to a touch down. The a/c departed the runway environment and ascended to an altitude of approx. 500 feet AGL. Upon reaching that altitude and in cruise flightm the flight instructor retarded the throttle, simulating a engine failure. The student pilot reduced the collective and entered a autorotaion. To maintain the rotor in the required parameters, the student pilot increased the collective. The rotor decayed to the point where the flight instructor joined the student pilot on the controls, lowering the collective to the full down position to regain the rotor RPM. The collective decrease failed to achieve the desired effect. The flight instructor attempted to increase the throttle to the full open position. The engine failed to respond to the increase sufficiently to increase rotor RPM. The a/c impacted the earth in a level, straight direction, destroying the aircraft. The flight condition was VFR. The wind condition was at or near zero.

As the FAA filed it

(-23) AT APPROX. 1410 LOCAL CST, N2301C, A ROBINSON R-22 HELICOPTER CRASHED WHILE PRACTICING SIMULATED ENGINE OUT PROCEDURES TO A TOUCH DOWN. THE A/C DEPARTED THE RUNWAY ENVIRONMENT AND ASCENDED TO AN ALTITUDE OF APPROX. 500 FEET AGL. UPON REACHING THAT ALTITUDE AND IN CRUISE FLIGHTM THE FLIGHT INSTRUCTOR RETARDED THE THROTTLE, SIMULATING A ENGINE FAILURE. THE STUDENT PILOT REDUCED THE COLLECTIVE AND ENTERED A AUTOROTAION. TO MAINTAIN THE ROTOR IN THE REQUIRED PARAMETERS, THE STUDENT PILOT INCREASED THE COLLECTIVE. THE ROTOR DECAYED TO THE POINT WHERE THE FLIGHT INSTRUCTOR JOINED THE STUDENT PILOT ON THE CONTROLS, LOWERING THE COLLECTIVE TO THE FULL DOWN POSITION TO REGAIN THE ROTOR RPM. THE COLLECTIVE DECREASE FAILED TO ACHIEVE THE DESIRED EFFECT. THE FLIGHT INSTRUCTOR ATTEMPTED TO INCREASE THE THROTTLE TO THE FULL OPEN POSITION. THE ENGINE FAILED TO RESPOND TO THE INCREASE SUFFICIENTLY TO INCREASE ROTOR RPM. THE A/C IMPACTED THE EARTH IN A LEVEL, STRAIGHT DIRECTION, DESTROYING THE AIRCRAFT. THE FLIGHT CONDITION WAS VFR. THE WIND CONDITION WAS AT OR NEAR ZERO.
