Circumstances:
Shortly after liftoff from Quebec-Ancienne Lorette Airport, en route to Montreal-Dorval Airport, the right engine caught fire. The captain contacted ATC, declared an emergency and was cleared to return for an emergency landing. He initiated a turn to the right when the airplane lost height, struck the ground and crashed in flames about 1,300 meters short of runway. Seven passengers were seriously injured while 17 other occupants were killed.
Probable cause:
It was determined that during initial climb, the low pressure impeller from the right (n°2) engine burst, causing the forward part of the engine to separate. The gear couldn't be raised because of engine debris damage to the electronic gear selection circuitry. This, including the exposed engine and lower cowl, increased the drag. In this configuration the aircraft wasn't capable of out-climbing obstacles straight ahead nor capable of maintaining altitude during the right hand turn. Engine separation and passenger movement resulted in the center of gravity shifting beyond its aft limit. The airspeed then decreased until the aircraft struck the ground at or below the minimum control speed (Vmc). Investigations revealed that the low pressure impeller burst due to the presence of fatigue cracks that had not been detected by the technicians in charge of the aircraft's maintenance.

Circumstances:
While flying over mountainous terrain, the pilot realized that the summit was shrouded by clouds. He decided to turn back and initiated a turn to the left when he lost visual contact with the ground. The airplane struck the ground and crashed on a snow covered area. The pilot was seriously injured and the passenger, seating in the cabin, was killed. It was reported that the aircraft was equipped with one seat only and the passenger was seating on the ground, without a seat belt.

Circumstances:
En route to Kuujjuarapik Airport (Poste-de-la-Baleine), about 25 miles from the destination, the pilot informed ATC about the deterioration of the weather conditions with low clouds and rain showers. Because he could see intermittently the airport, he decided to continue the approach. On short final, the airplane struck the ground and crashed about 300 feet short of runway threshold. The pilot, sole on board, was killed. The flight was completed on behalf of Brochu Industries.
Probable cause:
VFR approach in IMC conditions.

Circumstances:
The single engine airplane was returning to its base in Cochrane, carrying one pilot and two passengers flying back from a hunting camp. While cruising at low level so that the passengers could take pictures, the airplane went out of control and crashed in a wooded area located near Potter Lake. The aircraft was destroyed and all three occupants were killed.
Probable cause:
The cause of the accident could not be determined with certainty. However, it is believed that a moose was spotted and a steep turn was initiated. During the turn, the pilot lost control of the aircraft that went in a steep nose down and inverted attitude. It was reported that the aircraft did not have a ventral fin installed and this was not a legal requirement. The fin makes a float equipped aircraft much more directionally stable.

Circumstances:
On final approach to runway 27 at Komakuk Airfield, the crew was forced to increase the speed due to a 20 knots headwind. After touchdown, the pilot decided to veer off runway in order to avoid overrunning into a 7 meters embankment. The airplane went down a 1,5 meter embankment and came to rest with its both wings partially torn off. Both pilots escaped uninjured.

Circumstances:
The airplane departed Dragon Lake on a charter flight to Isaac Lake located 65 miles to the east, carrying three passengers and a pilot. En route, he encountered poor weather conditions when the seaplane struck trees and crashed in flames in a wooded area located about 12 miles northeast of Quesnel. The aircraft was completely destroyed by fire and all four occupants were killed. At the time of the accident, the visibility was limited due to low clouds.
Probable cause:
It was determined that the pilot lost control of the airplane while flying under VFR mode in IMC conditions. Investigations revealed that at takeoff, the aircraft was 359 pounds overweight and the centre of gravity was 1.5 inch aft of the aft limit. After 45 minutes of flight, the aircraft would be 200 pounds overweight with a centre of gravity located 0.5 inch aft of the limit.

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.
