The NTSB's narrative final · quoted from the NTSB record

The flight instructor and private pilot who was receiving instruction were practicing landings when the instructor asked "what would be his reaction if the engine quit on [the] downwind [leg]." They entered an autorotation from an altitude of 5,200 feet msl (600 feet agl) and an airspeed of 75 knots. The student turned the helicopter into the wind but lost 15 knots and rotor rpm (96 percent). The instructor noticed the rpm drop and added power, but there was no increase in rpm. Altitude had dropped to 4,900 feet msl (300 feet agl), and the rate of descent was increasing. The instructor kept the collective control down and pulled back on the cyclic control to transfer speed into rotor rpm and altitude. Engine and rotor rpm needles "were married at 93% and 95%." He increased collective to reduce the rate of descent. The throttle was fully open. The low rotor rpm horn never shut off, and there was no audible increase in rpm. The instructor said that as they passed 50 feet agl, the rpm was so low that "the helicopter was close to stall." He leveled off, but the helicopter struck the ground and bounced several times, collapsing the skids. It rolled over on its left side, shearing off the main rotor and tail rotor blades. The fuselage skin was also wrinkled. Nothing was found that would have precluded the development of engine power. Based on an instructor interview,the FAA concluded that the flight instructor should have had the student make a straight ahead autorotation instead of a turning autorotation. The student allowed rpm to drop so that it would have been difficult, if not impossible, to recover.
