MIA94LA060

Factual narrative

On January 24, 1994, about 1220 eastern standard time, N525BW, a Robinson R-22 Beta, operated by London Helicopters Inc. experienced a rollover while hovering on a 14 CFR Part 91 instructional flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The helicopter was substantially damaged and the instructor reported no injuries. The student pilot received minor injuries. The flight originated about 30 minutes earlier. The instructor pilot stated that they were practicing hovering autorotations and the student pilot executed the maneuver wrong. The student turned the throttle on instead of off, and then when requested would not release the flight controls. The right rear skid dug in the ground and the helicopter rolled over. THE CERTIFIED FLIGHT INSTRUCTOR DEMONSTRATED A HOVERING AUTOROTATION, THEN HE INSTRUCTED THE STUDENT PILOT TO EXECUTE THE MANUEVER. THE STUDENT PILOT ATTEMPTED THE HOVERING AUTOROTATION BUT OPENED THE THROTTLE INSTEAD OF CLOSING THE THROTTLE AS REQUIRED. THE INSTUCTOR PILOT ATTEMPTED TO REGAIN CONTROL BUT THE STUDENT PILOT DID NOT RELINQUISH CONTROL. THE HELICOPTER PITCHED UP, ROTATED 360 DEGREES TO THE LEFT, STRUCK THE GROUND, THEN ROLLED OVER AND CAME TO REST ON ITS RIGHT SIDE.
