The aircraft was dispatched at Wainwright Airport to practice cargo drop and parachute deployment test. While passing over the runway at low height, the aircraft went out of control, struck the runway surface and crashed, bursting into flames. Five crew members were killed in the accident. The call sign is not confirmed.
Those killed were:
Cpt Michael G. Allen,
Cpt Vincent L. Schurman,
M/WO Joseph Sylvio Castonguay,
Sgt Alain Michaud,
M/Cpl Ronald J. McWilliam.

Shortly after takeoff from Eucott Bay, BC, while climbing to a height of about 300 feet, the pilot initiated a turn to the left to perform a 180 circuit to leave the valley, a standard procedure for the area. While turning, despite power was added and the aircraft was climbing, it descended to the left then stalled and crashed in a wooded area located 450 metres west of the point of departure, bursting into flames. All five occupants were killed.

The single engine aircraft was engaged in a post maintenance test flight, carrying one engineer and two pilots. Shortly after takeoff from Villeneuve Airport, while in initial climb, the aircraft started to pitch up and down then lost height and crashed. The passenger was seriously injured while both pilots were killed, among them Billy Bourque, owner of Loon Air.

While taking off from an icy lake, the nose gear struck an ice ridge. The aircraft went out of control and collided with the river bank before coming to rest. Both pilots were slightly injured and the aircraft was damaged beyond repair. The accident occurred at 69°58'00.0"N 76°59'00.0"W.

After takeoff from Bronson Creek, while climbing to a height of 800 feet, the crew initiate a left turn when the left wing rolled to an angle of 30°. The aircraft stalled and crashed, bursting into flames. Both occupants were killed. The aircraft was carrying a load of gold.

Crashed on landing for unknown reasons. Both pilots were rescued and the aircraft was written off.

Following maintenance, the crew was engaged in a local test flight at Gimli Airport. Shortly after takeoff, while climbing steeply to a height of about 200 feet, the aircraft entered a right turn then nosed down and crashed near the runway, bursting into flames. All three occupants were killed.

The pilot departed the Air Saguenay base at Squaw Lake, Schefferville in northern Quebec around 07:00 local on a VFR flight to Desbergères Lake, about 210 miles to the northwest. The float-equipped C-FBSF was carrying six passengers and equipment for hunting caribou. Weather conditions deteriorated 30 minutes into the flight. The pilot entered a narrow valley some 50 miles northwest of Schefferville, then realised he could not clear the mountain peaks because of the lower ceiling in that area. When he tried to turn around to the left he flew into a fog bank. On emerging from the fog he saw the aircraft was going to strike the mountain. He raised the nose to minimize the force of the impact and tried to set the Otter down on the mountain side. The floats slid about 150 feet along the rocky surface, then broke off. The engine struck the ground and was torn off. The engine then rolled under the aircraft and came to rest on the right side of the fuselage. The Otter came to rest on the mountainside at an altitude of 2,650 feet. All passengers had been sitting on the right side of the aircraft and the baggage and equipment was stowed on the left side. The pilot and passengers were able to evacuate the Otter and there were no injuries. As they did so the Otter caught fire and burned for 45 minutes, consuming the fuselage. The wings fell to the ground after the wing supports melted. The fire died out after all flammable material was consumed. When radio contact with the Otter was lost, search aircraft were launched and located the crash site. The occupants were spotted at 11:30 and a rescue helicopter arrived at the site at 14:00 and all were rescued. There was however no rescue for the Otter which had been completely destroyed.

On approach to Island Lake Airport (Stevenson Island), the twin engine aircraft struck the surface of a frozen lake and crashed near Garden Hill. The pilot was slightly injured and the aircraft was damaged beyond repair.

The float equipped Beechcraft C18S was chartered to carry eight workers from Nanaimo to Port Mellon. After takeoff from the Nanaimo-Cassidy seaplane base, the pilot encountered difficulties to gain height. In poor weather conditions, the twin engine aircraft continued at a height of about 16 metres and rolled left and right. The aircraft entered a 30° left turn, causing the left wing tip to struck the water surface. The aircraft cartwheeled, crashed, exploded and sank. Quickly on the scene, in the Strait of Georgia, fishermen were able to rescue two passengers who were seriously injured (burned) while seven other occupants were killed.
