Robinson R22 Safety Record

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 due to fuel exhaustion as result of the pilot's failure to refuel en route. A contributing factor was the lack of suitable terrain available for the forced landing.

The loss of main rotor drive due to a drive belt separation resulting in a forced landing. A contributing factor was the lack of suitable terrain for the forced landing.

The directional control not maintained by the unrated helicopter pilot, and the remedial action not performed by the pilot-in-command. The pilot-in-command's lack of certification as a certified flight instructor and the dark night conditions were contributing factors.

the pilot's inadequate visual lookout and failure to maintain clearance from power lines. A factor was the pilot's decision to conduct cruise flight at a low altitude.

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 pilot's failure to maintain control of the helicopter after encountering dynamic rollover. A contributing factor was the deer pulling the aircraft unevenly.

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 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.
