What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On October 3, 2005, at approximately 0740 MST, N926SH, a Robinson R-22 helicopter, crashed while performing maneuvers during a CFR part 61 instructional flight. The pilot privacy data omitted was performing as pilot-in-command and providing flight instruction to privacy data omitted. During the performance of a simulated 180 degree autorotation, after privacy data omitted (student) entered the autorotation, he allowed the aircraft's airspeed to drop to 55 knots and the rotor RPM to decay to approximately 95%. As the aircraft rolled out of the turn, the pilot privacy data omitted recognized that the aircraft was not within standards, and assumed the flight controls. The pilot privacy data omitted attempted to perform a go-around by restoring power, however, operating RPM was not regained and power was not sufficient to prevent the aircraft from striking the ground. The pilot privacy data omitted leveled the aircraft and the aircraft touched down on a dirt road in a level attitude with a high rate of forward movement. The aircraft continued to slide forward for approximately 35 feet before the right skid entered soft sand to the right of the road. The aircraft began to roll end-over-end until it came to rest approximately 150 feet away. Both crew members exited the aircraft unassisted with only minor bruises and road rash. The aircraft was totally destroyed. This aircraft was operated by silverstate helicopters and performing flight instruction under CFR part 61.
