Robinson R44 Safety Record

The pilot's failure to see a wire cable prior to colliding with it. Factors contributing to the accident were the non-routine positioning of the wire cable, and the ground crew's failure to advise the pilot that the wire had been re-routed.

A total loss of tail rotor effectiveness. Contributing to the accident was the pilot's improper decision to operate inside the height velocity curve.

The in-flight separation of the tail rotor gear box for an undetermined reason. Contributing to the accident was the hilly terrain, which was unsuitable for a forced landing.

The student's inadvertent control interference, which the flight instructor was unable to overcome. A contributing factor was the instructor's poor crew coordination in his failure to verbally command the student to relinquish the controls and his inadequate supervision of the flight.

A malfunctioning magneto, resulting in a high engine rpm and low rotor warning indications. A contributing factor was the impact with a light pole, during the precautionary landing.

The loss of the engine to transmission drive train continuity while on approach for undetermined reasons. Contributing to the accident were lack of suitable terrain for a run-on landing, and cars on the race track.

The pilot's misjudged landing flare, inadequate bounced landing recovery, and failure to maintain directional control during a bounced landing that resulted in the tail rotor blades colliding with a hangar. Contributing to the accident was the burned out landing lights.

The pilot's failure to maintain aircraft control while maneuvering. Contributing to the accident were a tailwind condition and the pilot's inadequate in-flight planning/decision.

The pilot's delayed decision to perform a precautionary landing. Contributing to the accident was the reduced visibility in snow and the soft terrain.

Loss of control on the ground due to aircraft control not being maintained by the pilot. Contributing factors were the gusting winds and the uneven ground.

The reported vibration in the helicopter during an approach for landing for undetermined reasons. Contributing to the accident was the mature cornfield.

The pilot's improper planning/decision in attempting a downwind takeoff under high density altitude conditions that resulted in a loss of control and impact with terrain. Contributing to the accident were the helicopter's gross weight in excess of the maximum hover out of ground effect limit, a high density altitude, and the gusty tailwind.

the mechanic's improper installation of the attachment hardware for the servo to swashplate push-pull tube joint which resulted in a disconnection, subsequent loss of control, and impact with terrain. Contributing factors were the company management's inadequate surveillance and enforcement of maintenance procedures, the excessive maintenance workload due to inadequate staffing of maintenance personnel, and the insufficient management of maintenance tasks.
