Robinson R22 Beta Safety Record

The pilot's failure to maintain adequate main rotor rpm, and, his improper use of the collective, throttle, and anti-torque controls during the attempted recovery. Factors in the accident were the pilot's failure to completely relinquish the controls, and the high density altitude environmental condition.

The inadequate supervision by flight instructor for his failure to prevent incorrect anti-torque pedal input by the student resulting in the helicopter yawing at touchdown. A factor in the accident was the incorrect anti-torque pedal input by the student pilot while performing a practice auto-rotative landing procedure from a hover.

The loss of power for undetermined reasons. Also causal was the student's failure to maintain aircraft control and the instructor's inadequate supervision. The instructor's delayed remedial action as a contributing factor.

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 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 maintain altitude clearance during initial climb following takeoff during the commission of a crime, resulting in an in-flight collision with a tree.

The flight instructor's delay in taking remedial action to recover from a low rotor rpm situation. A factor was the student's failure to maintain adequate rotor rpm.

The pilot's inadequate preflight inspection which led to a contaminated fuel supply and subsequent loss of engine power. A factor was the lack of suitable terrain available for the forced landing.
