Hughes 269 Safety Record

the flight instructor's failure to maintain control of the helicopter while hovering. Contributing factors were the tailwind and gusty wind conditions.

The failure of the flight instructor to adequately monitor the student's rotorcraft control, resulting in an abrupt cyclic input causing a tail rotor strike of the terrain while entering a hover, and the resulting rollover during an uncontrolled descent.

the checklist not compiled with by the operator and not verified by the operator’s pilot and the operator's flight instructor. An additional cause was the improper autorotation by the pilot in command. The out of calibration engine idle speed was a contributing factor.

failure of the pilot-in-command to maintain adequate terrain clearance. Contributing factors were the unsuccessful low altitude flight maneuver, and the high density altitude weather conditions.

The pilot's failure to maintain rotor rpm during the simulated forced landing. Also causal in the accident was the failure of both pilots to recognize the total loss of engine power and the CFI's inadequate remedial actions. A factor in the accident was the loss of engine power for undetermined reasons.

The CFI's inadequate supervision and failure to maintain control of the helicopter during a practice autorotation. A contributing factor was the student's improper in-flight planning/decision.

Settling with power precipitated by a wind direction change during the approach to land sequence and the check pilot's delayed remedial action to correct the event. Factors in the accident were crew resource management coordination concerning flight control authority and unsuitable terrain for landing.

The pilot's failure to maintain control of the helicopter while maneuvering, which resulted in a hard landing. A factor in this accident was the pilot's lack of total experience in helicopters.

The pilot's failure to maintain control during a vertical, out of ground effect takeoff which resulted in a hard emergency landing. Factors were; the exceeded hover performance of the helicopter, the high density altitude, and the lack of suitable terrain for the emergency landing [high obstructions (trees) and soft ground].

The total loss of engine power due to a fatigue failure of the crankshaft for undetermined reason. A factor was the lack of suitable terrain for the forced landing.

The pilot refueled the helicopter with jet fuel instead of avgas, which resulted in a loss of engine power. A related factor was the unsuitable terrain.

the pilot's failure to properly plan the approach for landing, which led to a loss of tail rotor authority and directional control, while close to the ground. The tailwind was a related factor.

loss of engine power for undetermined reason(s); and the flight instructor's improper flare and improper use of the flight controls, while flaring for an autorotative landing.

failure of the student pilot to maintain directional control, inadequate supervision by the flight instructor (CFI), and subsequent failure of the pilot(s) to properly flare the helicopter during a hover autorotation.
