Robinson R22 Safety Record

Fatigue fracture of the clutch assembly fan shaft and the resulting complete loss of power to the rotor drive system. A contributing factor was the loss of tail rotor authority due to the secondary failure of the control tube assembly.

The student's failure to maintain adequate main rotor rpm, and the flight instructor's inadequate supervision of the flight. Contributing factors were the hilly terrain and the relative high density altitude conditions.

The loss of engine power for undetermined reasons. Factors were the low altitude, the trees, and the unsuitable terrain encountered for the forced landing.

the student pilot's failure to maintain adequate main rotor rpm, the CFI's delayed remedial action and inadequate supervision of the flight, resulting in a hard landing. Wind gusts and the high density altitude were factors in the accident.

The pilot's misjudged landing flare during an autorotation, which resulted in a hard landing. The pilot's failure to follow the listed emergency procedures in the rotorcraft flight manual and the partial failure of the rotor system's drive belts were factors.

The student's failure to maintain adequate main rotor rpm, and the flight instructor's inadequate supervision. Contributing factors were the high helicopter gross weight and density altitude, and the descending mountainous terrain.

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 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.

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 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.
