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) N453SH departed the Tucson airport on a training flight. Take off weight was calculated to be 1320 lbs. The flight lasted 30 minutes. Pilot stated: "the maneuver commenced with a 300 foot above ground level left downwind leg with the wing 90 degrees from the left. The student was in control of the aircraft at this time. Aircraft proceeded into the left turn base leg and then immediately on to final for the approach to a desert clearing. At this time the low rotor RPM horn was heard and the student was instructed to initiate the low rotor RPM recovery procedure. Vertical speed indicator was displaying an 800 foot per minute descent rate." The pilot stated that the low rotor recovery procedure did not respond as normally experienced. The pilot believes the student may have rolled the throttle in the wrong direction thus creating a delay in the recovery response time. The aircraft contacted the ground hard, remaining upright and slid forward two aircraft lengths prior to coming to rest. It was observed that the landing skids were deformed outboard, the main rotor blade(s) made contact with the tail boom causing a six to seven inch crease on the top side of the boom. Winds were 220-13 (gusting 23).
