De Havilland Dhc Safety Record

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.

A failure of the pilot to maintain adequate distance/clearance from a cement barricade while taxiing into a parking spot after landing. A factor was the presence of a barricade adjacent to the parking spot.

the pilot's failure to maintain aircraft control during the takeoff/initial climb. Contributing factors were the pilot's exceeding aircraft weight and balance limits and the dust devil.

The failure of the number 5 engine bearing assembly followed by the disconnection of the P2.5/P3 switching valve to rear inlet case sealing air tube and the melting of the NL probe port (sealing tube) which allowed an oil fed fire beyond the constraints of the engine casing and into the engine nacelle. A contributing factor was the company's failure to follow several maintenance procedures within the maintenance manual after a previous oil loss event. A second factor was the omission of the PW120A engine from the airworthiness directive issued by the FAA which mandated the completion of Pratt & Whitney service bulletin 20914. The lack of inclusion of the PW120A engine in the AD resulted in the company’s correct interpretation that the service bulletin was not mandatory.

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.

A malfunction of the aircraft's fuel selector valve and subsequent fuel starvation. Factors included a short emergency landing area, a wet landing surface, and a fence.

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.

The pilot's failure to maintain directional control during the takeoff run. A factor associated with the accident was the pilot's diverted attention while retracting the water rudders.

The pilot's failure to ensure attainment of adequate airspeed prior to initiating a steep turn at low altitude, resulting in an accelerated stall. A factor contributing to the occurrence of the accident was the aircraft's low altitude. Factors contributing to the severity of the accident included a water impact, and jammed/restricted doors due to impact damage resulting in degraded aircraft evacuation capability.

The failure of the flight crew to properly execute the emergency landing gear extension procedure in response to a landing gear unsafe cockpit indication.

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.
