If you fly, or plan to fly R-22 helicopters, this publication is essential reading, and could save your life. Special investigation of accidents involving loss of main rotor control in the R-22 was prompted, in part by a fatal accident that occurred during an instructional flight near Richmond, California. The flight instructor had 2,000 hours in the R-22, and the student had 4 hours. The helicopter was being operated at normal rotor RPM, within the approved flight envelope.
