The airplane was engaged in a cargo flight from Toronto to Seoul with intermediate stops in Edmonton and Vancouver, carrying two passengers, three crew members and a load of 86 Holsteins cows. Following an uneventful flight, the crew was cleared for an ILS approach to runway 29. At this time, weather conditions were considered as poor with limited visibility due to the night, snow falls and turbulences as a cold front was approaching the area. The copilot was in command and due to various factors, he failed to realize that the sink rate was too high on short final when the captain decided to regain control. Then the airplane struck poplar trees located 3,137 meters short of runway and electric cables, stalled and crashed in flames in a gravel pit located less than three km from the airfield. The aircraft was destroyed and all five occupants and 86 cows were killed.

Six minutes after takeoff from Edmonton Airport, the pilot informed ATC about an engine failure but preferred to continue rather than to return. Later into the flight, unable to maintain the prescribed altitude, the pilot elected to divert to Calgary Airport for a safe landing when on final, the airplane lost speed, stalled and crashed in a field. Both occupants were killed.

The pilot attempted to land on a short and narrow runway, without being able to determine the wind direction and strength. The aircraft landed downwind at a higher than recommended speed, bounced and touched down 1900 feet past the threshold. Braking action and deceleration were not satisfactory and the pilot elected to overshoot. Takeoff power was applied, but the gear struck a snow bank at the end of the runway and the F27 continued into trees, coming to rest 1800 feet beyond the end of the runway.

Crashed in unknown circumstances at an oilstrip owned by the Home Oil Company somewhere in Alberta. The occupant's fate remains unknown.

West Coast Airlines Flight 794 left Spokane, WA at 22:38 hours on a scheduled international flight to Calgary. The route flown was Spokane direct to Cranbrook. British Columbia. thence via Blue 3 to Calgary. At 23:33 hours Flight 794 reported to Calgary Terminal Control at 17 000 feet. The flight was then cleared to the Calgary VOR station at 13000 feet and requested to report by the Dyson Inter section. This was acknowledged and on request the latest Calgary weather was provided to the flight together with the altimeter setting (30.07 in Hg) and the runway to be used (28). Flight 794 reported by Dyson at 23:38 and was cleared to maintain 10000 feet. They were offered and accepted radar vectors to the localizer serving runway 28 and were then cleared for an approach. The flight was given a vector of 040 and advised it was south of the VOR station. At 23:46 hours the flight was advised it was 14 miles south of the localizer. Following successive vectors of 350° and 310° the flight was advised at 23:51 hours it was 1-1/2 miles south of the localizer and clearance was issued for a straight-in approach on interception of the localizer. Thirty-three seconds later the flight was informed it was 2 miles from the outer marker intersection and then at 2352 hours that it was over the outer marker intersection at which time it was requested to call the control tower. The flight called the control tower and reported over the intersection following which it was cleared to land on runway 28 and provided with wind information. An acknowledgement of this at 23:52 hours was the last transmission from the aircraft. It was determined subsequently that the aircraft struck the ground about 8000 feet before the threshold of runway 28 and 420 feet to the right of the centreline of that runway. It slid for a distance of about 800 feet before coming to rest. At the time of impact the aircraft was approximately in a 5° nose-down attitude. Four occupants were slightly injured while 11 others were unhurt. The aircraft was damaged beyond repair.

On October 17, 1958 a Beaver belonging to the USAF took off from Grande Prairie, Alberta en route to Edmonton, AB., for a routine maintenance inspection. On board were Capt. William Varns, Capt. Walter Brown, Lt. Lawrence Anderson and Sgt. Jackie Herth from the 919th Squadron, Saskatoon Mountain Air Squadron, Beaverlodge, AB. Two hunters were reported missing in the area of Nose Mountain, south of Grande Prairie, and the flight was side-tracked to search for them. The hunters were spotted and the crew radioed that they were going down closer to enable them to drop a note to the hunters. That was the last word from them. A civilian plane with an USAF Sgt. aboard was dispatched from the Grande Prairie airport to search for the missing aircraft. They located it, but had no radio so had to return to Grande Prairie to report. Meanwhile a RCAF Search and Rescue aircraft from Namao, Alberta was dispatched. When they located the crash site, they radioed in the location and continued to circle until a RCAF helicopter from Dawson Creek, British Columbia, reached the site. The helicopter picked up the injured airmen and radioed back that “One of the chaps didn’t make it.” The injured were airlifted to Grande Prairie, AB., and transported by ambulance to the hospital in Beaverlodge. The hunters stayed at the crash site overnight and were airlifted out early the next day when the helicopter returned to fetch the body of Capt. William Varns. The two hunters were praised for their help in assisting the injured airmen. Airframe buried at crash site.

The aircraft departed Edmonton at 1137LT on a flight to Port Radium, NWT, with refuelling stops at Fort Smith and Yellowknife, NWT. The aircraft climbed to 9,000 feet on a direct route to Fort Smith. Between Edmonton and Fort McMurray, it encountered light rime ice which was easily disposed of by the deicing equipment. At approximately 1320LT, the aircraft was abeam Fort McMurray and encountered freezing rain about five minutes later. The course was altered for Embarras with the intention of joining the airway and following it as far as Fort Smith. The build-up of ice was very rapid at this time and could not be overcome by the deicing equipment. The crew requested permission to descend to 7,000 feet and during the descent additional ice was picked up. The aircraft could not maintain height at 7,000 feet and went down to 5,000 feet, still running through rain squalls. Throttle and propeller settings were for 40" and 2 500 rpm respectively. Further altitude was lost and at about 4,500 feet, severe turbulence was encountered. This together with the accumulation of ice, caused a further loss of height, and the aircraft collided with trees. The pilot closed the throttles and at 1352LT and carried out a forced landing. Both pilots suffered serious injuries and the aircraft was destroyed.

At 0021LT the aircraft departed Edmonton for Yellowknife with a crew of two, four passengers and a cargo of freight. An IFR flight plan had been filed for the flight to be made at 5,000 feet over Blue Air Route No. 84. Clearance out of the Edmonton Control Area was given to the aircraft but VFR was to be maintained while in the area. About twenty-two minutes after take-off, the tower at Namao heard a distress message from the aircraft indicating that the starboard engine had failed and that the aircraft was returning to Edmonton at 3,000 feet. Two minutes later another distress message was picked up by Namao stating that the aircraft was returning to Edmonton. Two-way communication with the aircraft was not established and although Namao and Edmonton continued to call the aircraft for more than thirty minutes, nothing further was heard from it. Although hampered by darkness and poor weather conditions, an air and ground search was started almost immediately but without success, until shortly after first light when the wreckage was found in a farm field about ten miles north of Thorhild. The captain and one passenger had been killed and the copilot and three other passengers were seriously injured. The aircraft was destroyed.

The aircraft took off at approximately 1700LT on a local test flight carrying a crew of 2 and 4 passengers. The purpose of the flight was to test the single-engine performance of the aircraft when loaded to the maximum permissible weight for take-off and to determine the correct power setting and performance. Just before 1705LT witnesses stated that they saw the aircraft turn onto its back with a sudden cessation of engine noise and white or grey vapor was seen to come from both engines as it dived in a very steep nose down attitude to the ground. From statements of witnesses it was deduced that it was probable that the aircraft was below 1,000 feet when it turned onto its back. The aircraft exploded on impact and caught fire. All the occupants were killed and the aircraft was destroyed.
