Schweizer 269C Safety Record

the loss of engine power for undetermined reasons during takeoff. Factors were the vehicles, the unsuitable terrain the pilot encountered, and the low altitude of the helicopter at the time of the loss of engine power.

a loss of power for unexplained reasons. Also causal was the CFI's operation of the helicopter in a region of the height/velocity curve where a successful autorotation could not be accomplished. A factor in the accident was the high density altitude.

The pilot's inadequate in-flight planning/decision to attempt a hover in atmospheric conditions and over terrain that would require maximum helicopter performance, and which would leave no viable alternate actions in the event of difficulties.

the pilot's failure to maintain translational lift while maneuvering, and the loss of tail rotor effectiveness. Factors relating to this accident were the tailwind, low airspeed, low rotor rpm, and the pilot's lack of overall experience in helicopters.

The student's improper execution of a quick-stop maneuver in that he misjudged his altitude and failed to terminate at a stationary hover prior to descending to a low hover. This resulted in an excessive engine power requirement and the student improperly coordinated the use of the collective and anti-torque controls.

The pilot's use of improper procedures by not following the helicopter manufacturer's recommended engine RPM reduction procedures during autorotations. A factor was the pilot not attaining the proper rotor RPM during the autorotation practice.

The inadequate supervision of the student pilot by the flight instructor during the practice autorotation, which resulted in a delayed flare and the tail rotor contacting the ground. A factor was a misinterpreted communication between the flight instructor and student.

inadequate assembly instructions from the engine manufacturer which resulted in improper engine assembly, and subsequent power loss over unsuitable terrain, with insufficient altitude for a successful autorotation.

the pilot's failure to maintain control of the helicopter. Factors associated with the accident were the high winds, low altitude at which the pilot was maneuvering and the uneven terrain which the helicopter contacted.

The pilot's failure to adequately secure the cargo strap which became entangled in the tail rotor, leading to a loss of the tail rotor control. This was followed by an improperly executed emergency procedure and an in-flight collision with the ground. A factor was the inadequate procedure supplied by the manufacturer.

the pilot's inadequate preflight planning which resulted in a low fuel state, and his inability to see the wire which the helicopter contacted. Factors associated to the accident were the precautionary landing, the dark night conditions, and the wire which was contacted.

A total loss of engine power which was a result of incomplete and improper engine overhaul by company maintenance personnel. A factor in the accident was the unsuitable forced landing area terrain.
