De Havilland DHC-6 Safety Record

the pilot's failure to maintain airspeed following a loss of power in the right engine due to the fracturing of compressor turbine blades for undetermined reasons. Contributing to some parachutists' injuries was the lack of a more effective restraint system on the airplane.

The pilot's inadequate compensation for the gusty crosswind wind condition, which resulted in a loss of control during the landing roll, and the collapse of the nose landing gear. Factors associated with the accident were the crosswind and wind gusts.

The failure of the captain to maintain adequate clearance between the airplane's wingtip and a parked vehicle. A factor contributing to the accident was the failure of ground personnel to utilize a wing walker as prescribed in company policy when aircraft are operated near obstacles.

The captain's inadequate compensation for crosswind conditions, and his failure to maintain directional control during the landing roll on an icy runway, which resulted in an excursion from the runway and collision with a snow berm. Contributing factors in the accident are a crosswind, an icy runway, and a snow berm.

The failure of a ground handler to follow company proceedure/directives, and his premature release of a mooring line. Factors associated with the accident were the congested operations area, and the operator's failure to provide adequate safe zones for the airplanes.

the King Air pilot's inadequate in-flight planning/decision in that he failed to remain in the agreed on formation position, resulting in one of his skydiver's contacting the propeller of the de Havilland airplane. A contributing factor was the lack of total experience of both pilots in multiengine formation air drop flights.

the loss of power to both engines for undetermined reasons during approach. Contributing factors were the pilot's failure to properly position the fuel selector in accordance with the landing checklist and the lack of suitable terrain for the forced landing.

the pilot's continued VFR flight into IMC conditions, by failing to maintain altitude, and descending from VFR conditions into IMC, which resulted in him subsequently impacting with trees. Factors in this accident were: reduced visibility due to dark night and fog. An additional factor was the pilot was not certified for instrument flight.

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 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 failure to secure the engine oil filler cap during the preflight inspection that resulted the subsequent loss of engine power, and his in-flight decision to attempt a single engine go-around with full wing flaps extended.
