Circumstances:
The DC-3 aircraft, with the captain, first officer, and an apprentice aircraft maintenance engineer on board, was to be ferried from Vancouver, British Columbia, to Whitehorse, Yukon. Just after take-off from runway 08, as the first officer was setting the engine power, the right propeller began to over-speed. The captain told the first officer to shut down and feather the right engine. The first officer did as instructed, and advised the Vancouver tower controller of the engine problem and that they would return to the airport to land on runway 08. The captain turned the aircraft to the right, onto downwind for runway 08; however, because the aircraft's altitude and airspeed were decreasing, the first officer advised the tower controller that they would land on runway 30. The aircraft continued to lose height, narrowly avoiding buildings in its path, and crashed to the ground, one mile short of runway 30. The three occupants were seriously injured during the impact and the post-crash fire; the captain died of his injuries eight days after the accident.
Probable cause:
The aircraft's right engine oil system malfunctioned for reasons that were not determined, and the right propeller did not completely feather during the emergency shutdown. The aircraft was unable to maintain flight because of the drag generated by the windmilling right propeller.

Circumstances:
On 11 January 1995, at 0035 Pacific standard time (PST), the twin-engine Learjet 35 departed Vancouver International Airport, British Columbia, on a night, instrument flight rules (IFR), medical evacuation (MEDEVAC) flight to the Masset aerodrome, on the northern end of the Queen Charlotte Islands. On board the Learjet were a flight crew of two pilots, and a medical team consisting of two attendants and a doctor. Their mission was to evacuate a patient from Masset and deliver her to Prince Rupert for treatment; the aircraft was then to return to Vancouver. The flight-planned route was at flight level (FL) 390, direct to Sandspit then direct to Masset. Following routine communications with Air Traffic Services (ATS), at about 0144, the aircraft reported "outbound" from the Masset non-directional beacon (NDB) on the published NDB "A" instrument approach procedure to runway 12. Air Traffic Control (ATC) radar, situated near Sandspit, tracked the aircraft as it flew the approach. Radar data shows that the aircraft began a descent about 10 seconds after it had completed the procedure turn and was established on the final inbound approach track. Forty-three seconds later, at a point 8.8 nautical miles (nm) from the threshold of runway 12 and on the final, inbound track, the aircraft disappeared from radar. Department of National Defence (DND) Search and Rescue (SAR) aircraft began searching the area shortly after the aircraft was declared missing, and were later assisted by other private and military aircraft and vessels. On the second day of the search, flotsam from the aircraft was found in the area. Extensive underwater searching using sonar and underwater cameras found the aircraft wreckage on 31 January 1995, in 260 feet of water, near the last known position. The aircraft had been destroyed. The bodies of two occupants were found several days after the accident, but the other three occupants have not been found and are presumed to have been fatally injured. The accident occurred at latitude 54/08NN and longitude 131/58NW, at about 0149 PST, during the hours of darkness in unknown weather conditions.
Probable cause:
The crew most likely conducted the instrument approach with reference to an unintentionally mis-set altimeter of 30.17 in. Hg, and unknowingly flew the aircraft into the water. The circumstances leading to the incorrect altimeter setting could not be determined, nor was it determined why the crew did not detect the mis-set altimeter.

Circumstances:
The pilot was supposed to proceed under VFR mode to the west but as weather conditions deteriorated with low clouds, he decided to continue to the south. While flying between two mountains, the single engine aircraft encountered atmospheric turbulences and the pilot elected to return when the aircraft lost height and struck trees. Upon impact, both wings were torn off and the aircraft crashed in a wooded area. All 11 occupants were injured, four of them seriously.

Circumstances:
Flight 106 was a schedule service from Vancouver to Powell River with an intermediate stop at Sechelt. The flight to Sechelt was uneventful. While approaching Porpoise Bay at Sechelt, at an altitude of 200 feet, the twin engine airplane rolled to the right in an angle of 90° then nosed down and crashed on the east shore of the bay, about 50 meters from the water. The captain and a passenger were killed while 14 other occupants were injured, four of them seriously.
Probable cause:
The right-hand aileron bellcrank-to-aileron rod had separated from the bellcrank end fitting due to an extensive stress corrosion crack. This allowed the right-hand aileron to move up, causing asymmetric lift and irretrievable loss of control. The specified visual inspection of the rods was inadequate to detect stress corrosion cracking. Previous similar failures of flap rods on the DHC-6 had led to airworthiness action by the manufacturer and the DOT but these measures were not applied to the aileron rods which are of similar construction.

Circumstances:
Twin Otter C-FAIV, operating as a scheduled VFR flight, departed Victoria Harbour at 1718LT with Vancouver Harbour water-aerodrome as destination. The estimated time en route was 20 minutes. The flight proceeded normally and reported by Active Pass at 2,000 feet. This altitude was maintained in order to cross the Vancouver Control Zone in accordance with standard procedure; once out of the control zone, a slow descent was begun towards Vancouver Harbour. Normal radio procedures were followed as the flight reported by standard visual reporting points. Just before joining final approach, the transmission, "AIV, Third Beach", was made and landing clearance was given to the flight by the Harbour Tower. The approach continued, and when the aircraft reached approximately 175 feet above the surface, nine ground witnesses heard a loud noise from the aircraft. Two surviving witnesses also heard a noise. Power was subsequently applied and C-FAIV yawed left, rolled in the same direction and plunged into the harbour in a left-wing and nose-down attitude, 2 500 feet from the intended landing area. An ELT (Emergency Locator Transmitter) tone was heard by the tower controller 54 seconds after the radio call at Third Beach. The controller called the aircraft several times but there was no response. The flight had been of 24 minutes duration. Both pilots and nine passengers were killed while two others were injured. The aircraft was destroyed.
Probable cause:
The following findings were determined:
- The final approach to land was normal until an unusual noise occurred followed by loss of control,
- The aircraft dived into the water with left wing down, nose down and with some sideslip. Value of roll, pitch and yaw, at impact could not be estimated with useful accuracy,
- At impact, the complete left flap system was in the retracted position,
- The inboard span-wise push-pull flap control rod (inboard bell-crank to inboard rod, PT # C6CW-1029-1), was severely stress-corroded and had at least three longitudinal cracks; the rod had separated from its inboard fitting,
- It was deduced t h a t t h e in-flight failure of the left-hand inboard flap control rod led to sudden retraction of the complete left-hand flap system and sudden loss of control.
- The passengers had not been briefed in evacuation procedures,
- The crew was qualified for the type of operation in accordance with Transport Canada regulations. After the failure of the left flap control rod, no action by the pilot could have averted the accident.

Circumstances:
The Convair approached Campbell River with the weather just above minima (2-2,5 miles visibility, 400 feet broken ceiling and wind 110 degrees with gusts to 20 mph. The crew positioned the aircraft visually 2nm south of the airfield on a westerly heading preparatory to attempting an approach to the west. This would involve a right hand circuit flown above the broken south and west of the airport employing DME and ADF information. This improvised approach was not in accordance with published approach procedures under instrument conditions. After flying for 1 minute and 40 seconds the crew turned right. A few seconds after the captain expressed concern, the Convair struck a 1047 feet hill at 932 feet.
Probable cause:
Wrong approach configuration on part of the flying crew who failed to comply with the approved instrument approach procedure.

Circumstances:
The approach to Vancouver Airport was completed in poor visibility due to foggy conditions. Following a wrong approach configuration, the aircraft landed 1,000 feet past the runway threshold and to the right of the centerline. After touchdown, the captain decided to make a go-around when control was lost. The airplane veered off runway to the right, went through the tarmac and eventually collided with a terminal building. Seventeen occupants were injured while 43 others were unhurt. The copilot and one person in the terminal were killed. The aircraft was considered as damaged beyond repair. At the time of the accident, the horizontal visibility was limited to 200 meters due to fog with strong winds.
Probable cause:
It was determined that the approach configuration on part of the flying crew was wrong. At the time of the accident, both pilots were on duty since more than 21 hours and their concentration and performances were diminished due to intense fatigue. It was reported that the approach speed was too high while the rate of descent was too low.
