Circumstances:
The aircraft was on a scheduled visual flight rules (VFR) flight from Terrace to Iskut to Dease Lake to Bronson Creek and back to Terrace, British Columbia. The aircraft departed Terrace about 1005 Pacific standard time (PST) and arrived Iskut about 1145, departed Iskut about 1155 and arrived Dease Lake about 1230, and departed Dease Lake about 1250 and arrived Bronson Creek about 1340. All of these flights were completed without incident, and the aircraft departed Bronson Creek for Terrace at about 1350 with the pilot and three passengers on board. Ten minutes later, the pilot spoke on the radio to a pilot who was flying from Smithers to Bronson Creek when the two aircraft passed each other approximately 20 miles east of Bronson Creek. This was in the Iskut River valley just east of the confluence of the Forest Kerr River and the Iskut River. This was the last reported contact with the aircraft, and the pilot did not report a problem at that time. An air and ground search was started after the aircraft was reported missing, but the aircraft was not found and the search was abandoned. No emergency locator transmitter (ELT) signal was detected. The wreckage was found by chance on 05 August 1994, nearly four years after the accident.
Probable cause:
The pilot likely attempted to continue the visual flight into an area of instrument meteorological conditions.

Crash of a De Havilland DHC-5D Buffalo in Calgary

Circumstances:
The aircraft suffered an incident in Ecuador few days prior to this accident and damages were reported to the undercarriage. A ferry flight to Calgary was arranged so the aircraft could be repaired by technicians by De Havilland Canada. The flight from Quito to Calgary was completed with the undercarriage down. Upon touchdown on runway 28 at Calgary Airport, the nose gear collapsed. The airplane slid on its nose and came rest, bursting into flames. In a hurry, both pilots escaped the cabin and did not stop both engines. Hydraulic fluids ignited and the aircraft was totally destroyed by fire. Both pilots were uninjured. Dual registration FAE064 and HC-BFH.
Probable cause:
It was concluded that the self-centering mechanism could be forced off centre because of a system malfunction caused by the previous accident or by intentional nosewheel steering input, which would cause enough pressure to shear the pins. The internal damage to the controlcam mechanism allowed the wheels to be off centre at touchdown. Marks on the adjacent sides of the pulleys showed that the cable had been lodged in the space between the two pulleys. Although the extent of this damage was limited, it was representative of damage caused by the previous jungle accident and would have caused the sluggish response to nosewheel commands experienced earlier by the crew. When the weight of the aircraft settled on the misaligned nosewheel, the temporary ferry repairs failed in overload and the nosewheel collapsed.
