Robinson R22 Beta Safety Record

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 inadequate flare resulting in rotor blade contact with the ground. Contributing factors were the high altitude and the airframe vibration for an undetermined reason.

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 pilot's poor decision to continue the flight into the rising mountainous terrain, and subsequent failure to maintain clearance with the trees. Contributing factors were rising mountainous terrain, the high density altitude, and the exceeded weight and balance and performance capability of the helicopter.

The failure of the flight instructor to properly judge the landing flare and add adequate cyclic, resulting in a hard landing which collapsed the left skid. The wind gusts were a factor.

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 failure to ensure that adequate altitude/clearance above the ground was maintained during hovering flight, resulting in an inadvertent ground contact and subsequent loss of control of the helicopter. A factor was the flight instructor's failure to ensure adequate control of the aircraft was maintained in the hover.

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 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 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 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 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.

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.
