Robinson R22 Safety Record

An excessive descent rate during a simulated power-off autorotation, and the pilot's failure to initiate corrective action in time to keep the helicopter from impacting the terrain.

The pilot's failure to maintain aircraft control during an encounter with the loss of tail rotor effectiveness. Contributing factors were the high density altitude and the power lines.

The certified flight instructor's inadequate supervision of the practice autorotation. Contributing factors included the terrain drop off and the failure of the pilot undergoing instruction to maintain adequate rotor rpm.

The student pilot's improper use of the flight controls, which induced a dynamic rollover. Also causal was the certificated flight instructor's inadequate supervision and delayed remedial action.

Clearance was not maintained after landing by the instructor pilot, which resulted in an on ground collision with the helicopter standing near the refueling pumps. The aircraft standing in the refueling area was a factor.

The flight instructor's failure to maintain aircraft control during the flare/touchdown while practicing an autorotation which resulted in a hard landing. A factor which contributed to the accident was the downdraft wind condition.

The student pilot's improper use of the collective and cyclic control, which induced a dynamic rollover. Also causal was the certificated flight instructor's inadequate supervision and delayed remedial action.

The flight instructor's inadequate remedial action following a loss of control in flight. A factor to the accident is that the dual student did not maintain directional control of the helicopter while manuevering, which subsequently caused the instructor to lose control of the helicopter.

The flight instructor's selection of an unsuitable landing site, which resulted in an inadvertent dynamic rollover during landing. A factor associated with the accident was the inadvertent dynamic rollover.

The student's misjudged landing flare, the instructor's inadequate supervision of the flight, and the instructor's failure to maintain adequate rotor rpm.

the student pilot's inadequate compensation for wind conditions and the instructor's failure to arrest the descent, which resulted in a dynamic rollover. Also causal was the inadequate supervision by the instructor. A factor in the accident was the wind shift to a tail wind condition.

the pilot's failure to maintain aircraft control. Contributing factors in this accident included the sudden wind shift and high density altitude, resulting in the helicopter settling with power, and the high vegetation.

The pilot's failure to maintain adequate rotor rpm and adequate terrain clearance while maneuvering to reverse direction. Contributing factors were the high density altitude, that exceeded the helicopter's performance capability, and the rising mountainous terrain.

The pilot's intentional decision to leave the helicopter unattended with the engines running which resulted in a dynamic rollover. The inadvertent dynamic rollover was a factor.
