Robinson R22 Safety Record

The inadvertent dynamic rollover the student pilot encountered following his excessive control inputs during the takeoff portion of the instructional flight and the instructor not performing the remedial action necessary to reduce the excessive control inputs by the student.

The flight instructor's delayed remedial action during a practice autorotation. Factors included the flight instructor's overconfidence in the pilot receiving instruction, and that pilot's improper recovery from a practice autorotation.

the student's excessive rate of descent during a practice autorotation, and, the inadequate use of the rotorcraft flight controls by both pilots during the attempted recovery, which resulted in a hard landing. The flight instructor's inadequate supervision during the maneuver was also causal.

the failure of the main rotor drive belts while maneuvering which resulted in a loss of main rotor drive. A contributing factor was the lack of suitable terrain for the forced landing.

an in-flight collision with the ground during a simulated engine failure, and autorotation, which resulted in the tailboom separating. A contributing factor in this accident was the pilot allowed the rotor rpm to decay which resulted in inadequate rotor rpm to cushion the helicopter onto the ground.

Both pilots' exceedance of the proper descent rate during the autorotative descent. Factors included the helicopter's low altitude at maneuver initiation, the failure of both pilots to maintain the proper airspeed during the descent, and both pilots' delay in initiating remedial action.

The failure of the instructor to take corrective action in a timely manner to prevent the helicopter from contacting the ground when the student allowed it to descend during hover practice which resulted in a dynamic rollover.

The student pilot's failure to relinquish the flight controls while the CFI was demonstrating a takeoff to a hover. This resulted in an in-flight loss of directional control, in-flight collision with terrain, and subsequent roll over.

The flight instructor's inadequate supervision of his student and his failure to maintain control of the helicopter. Factors were the student pilot allowing the airspeed and main rotor RPM to get too low during the simulated emergency.

The pilot-in-command's inadequate supervision of the second pilot and delay taking control of the aircraft and implementing remedial action. A factor in the accident was the second pilot's interference with the pilot-in-command's operation of the collective flight control.

The certified flight instructors disregard of an FAA weather forecast stating VFR flight not recommended resulting in VFR flight into known instrument flight conditions, loss of aircraft control due to spatial disorientation, and subsequent in-flight descent and in-flight collision with the Atlantic Ocean.

The dual student's improper use of the collective and the flight instructor's inadequate supervision during the practice hovering autorotation maneuver. A factor was the underlying soft dirt terrain, which promoted the rollover event.

The divergence of the main rotor from its normal plane of rotation for an undetermined reason, which resulted in mast bumping and rotor contact with the fuselage.

The student pilot's failure to maintain altitude clearance during initial climb following takeoff during the commission of a crime, resulting in an in-flight collision with a tree.
