De Havilland Dhc Safety Record

The pilot's selection of an unsuitable takeoff area, and an inadvertent stall. Factors associated with the accident were large wave/swells, and low light conditions (dawn).

A failure of ground handling personnel to verify a release procedure/directive, and removal of the airplane's tiedown, and subsequent collision with a parked airplane.

The certificated flight instructor's inadequate supervision of the duel student. Factors associated with the accident were the student's inadvertent stall, and a surging turboshaft engine.

The pilot's selection of an unsafe/hazardous area for landing. Factors in the accident were the presence of a tail wind, the pilot's inadequate evaluation of the wind conditions, and a narrow airstrip.

the mechanical separation of the left engine beta control linkage during landing rollout, which resulted in asymmetrical decelerative action and the pilot's subsequent inability to maintain directional control. The separation of the linkage was due to the airline's inadequate inspection and quality assurance procedures. An inoperative windsock pivot point, which resulted in faulty wind direction information to the flight crew was a factor in this accident.

The pilot's inadequate preflight which failed to detect water contamination in the fuel system. A factor was the unsuitable terrain in the emergency landing area.

The pilot's inadequate compensation for the gusty wind conditions, and his attempted flight into adverse weather. Factors associated with the accident are high and gusty winds.

The failure of maintenance personnel to correctly diagnose and correct a reoccurring nose gear steering problem, and the improperly tensioned nose wheel steering actuator cables which provided the pilot with an erroneous cockpit indication that the nose gear was centered when it was cocked.

The pilot's misjudged touchdown which resulted in dragging the right wingtip and rupturing the fuel tank. A factor associated with the accident is the rough water conditions.

failure of the ground marshaller to marshal the airplane into a correct parking place on the ramp, her failure to verify clearance between the right wing of the airplane and the ground de-ice cart, and failure of the flight crew to ensure clearance of the right wing as the airplane was being taxied into the parking place. Factors relating to the accident include: a congested ramp facility, and inadequate ramp markings.

a missing 'C' clip, which resulted in the master link coming apart, allowing the electric elevator trim chain and cable to become entangled in the elevator trim cables.

a fractured fusion weld in the piston of the roll spoiler servoactuator, which allowed the plug at the base of the piston to separate and jam the piston. A factor relating to the incident was: the inadequate design of the airplane's roll spoiler servoactuator piston.

a fractured fusion weld in the piston of the roll spoiler servoactuator, which allowed the plug at the base of the piston to separate and jam the piston. A factor relating to the incident was: the inadequate design of the airplane's roll spoiler servoactuator piston.

A failure of the normal landing gear extension system due to a hydraulic leak, and the failure of the airplane's emergency landing gear extension system due to inadequate servicing by company maintenance personnel. Factors were the emergency landing gear extension systems dirty and binding condition, a worn emergency landing gear extension cable, and the training simulator's lack of fidelity concerning the force required to operate the emergency gear extension T-handle.

THE PILOT'S INADEQUATE COMPENSATION FOR THE WIND CONDITIONS DURING THE LANDING APPROACH, AND HIS FAILURE TO MAINTAIN ALTITUDE/CLEARANCE FROM TREES. A FACTOR RELATING TO THE ACCIDENT WAS: THE GUSTY WIND CONDITION.
