After takeoff from lake Helen, the pilot raised the flaps and reduced the speed when the aircraft stalled and crashed in a wooded area, bursting into flames. Both occupants escaped with minor injuries while the aircraft was destroyed by a post crash fire.

Crashed upon landing for unknown reasons. There were no casualties.

The CC-130H registered 130331 was engaged in a local demonstration flight under callsign Trucker 2, taking part to the celebration of the RCAF 60th anniversary. While approaching the airbase, it collided with a second RCAF CC-130H registered 130330 (callsign Trucker 1). Both airplanes crashed and were destroyed. All 10 occupants in both aircraft were killed, four crew members in each aircraft plus two observers on board 130330.

The twin engine aircraft departed Sanikiluaq Airport on an ambulance flight to Churchill, MB. In unknown circumstances, it crashed on Belcher Island, about 45 km southeast of Sanikiluaq Airport. Both pilots and the medevac passenger were killed.

En route from Edmonton to Peace River, while cruising by night, the crew encountered marginal weather conditions. Due to interferences, the crew was unable to receive the signal from the Whitecourt VOR and thought he already overflew the mountain range located southeast of High Prairie. Too low, the aircraft struck tree tops, stalled and crashed in a wooded area covered by snow and located on Mt Swan, southwest of Lesser Slave Lake. The wreckage was found the following day in an isolated area. A pilot and three passengers were injured while six other occupants were killed, among them the Canadian politician Walter Grant Notley aged 45.

On approach to Toronto-Lester Bowles Pearson Airport, the twin engine airplane struck the ground and crashed about 11 km short of runway threshold. All three occupants were killed.

The Twin Otter departed Goose Bay on a medical evacuation flight to St. Anthony. The flight was uneventful and landed in St. Anthony at 15:24. At 16:02, the aircraft departed St. Anthony on a VFR flight back to Goose Bay. On board were the two pilots and the doctor and nurse. Approaching the Goose Bay Airport, weather became marginal, but the crew continued visual flight. The crew likely encountered near zero forward visibility in snow showers and fog; it is probable that they were able to maintain vertical contact with the ground and were confident they could continue flight with visual reference to the ground. The crew may not have been able to see terrain ahead and therefore may not have been able to determine if the aircraft would clear the hills, particularly, when steep hills were encountered. The plane struck a rock outcropping 100 feet below the summit of a 2,050-foot mountain. After bouncing twice, the Twin Otter had come to rest in a small, wooded gully, approximately 350 feet from the initial point of impact.

The aircraft departed Fort Norman at 16:51 and arrived overhead Fort Franklin at approximately 17:15. Because Fort Franklin was shrouded in fog, a local resident contacted the pilot on a portable VHF transceiver and advised him that there was little or no visibility. The pilot replied that he did not think he would be able to land. The resident drove to the airstrip and contacted the pilot again when he heard the aircraft returning. He advised the pilot that visibility was 200-300 feet. The pilot then asked if this was the vertical or horizontal visibility. At that moment the Twin Otter struck a 200-foot-high telecommunications tower while in controlled level fight. Part of the right wing broke off and the aircraft slowly rolled over before striking the ground. The decision of the pilot to continue the approach in foggy weather were possibly influenced by the effects of stress and a greater than usual personal need to complete the flight. The stress was probably caused by the fact that the pilot had been involved in four accidents since March 1984. Although he was a very experienced pilot, his previous employer terminated his employment on 31 August 1984. In their opinion, his ability to make operational decisions was in question. The pilot was hired by Nahanni Air Services one month later.

The crew departed Toronto-Lester Bowles Pearson Airport at 1107LT on a training flight to Muskoka Airport. En route, while cruising at an altitude of 9,500 feet, the crew was cleared to make a low pass over Orillia Airport. Following a passage at an altitude of about 150-200 feet and a speed of 200 knots, the crew initiated a climb when, at an altitude of 1,000 feet, the aircraft banked right then got inverted and crashed in a near vertical attitude. The aircraft was destroyed and both pilots were killed.
