Circumstances:
The airplane departed the Polar Station SP-21 in the early morning on a flight to the North Pole (Arctic region) with six crew members and three scientists (hydrologists) on board, and was used for communications with Soviet submarines cruising in the Arctic zone. The crew found a suitable area to land located about 500 km north of the Queen Elizabeth Islands, NWT. After landing, the scientists proceeded to ice inspection and it was reported that the ice thickness was 47 cm, which was considered as insufficient to leave the aircraft parked for a long period. The decision was taken to leave the area to find another one when the left ski went through the ice, followed shortly later by the right ski. The aircraft was blocked into the ice and impossible to move. Due to the presence of sensible equipments on board, it was decided to destroy the airplane that partially sank. All nine occupants were evacuated two days later by the crew of an Antonov AN-2.

Circumstances:
While descending to Montreal-Dorval Airport, the crew encountered poor weather conditions and a limited visibility due to snow falls. Unable to locate the runway, the captain decided to abandon the approach and initiated a go-around manoeuvre. Few minutes later, a second attempt to land was also abandoned for similar reasons. During a third attempt, the crew descended below the glide to establish a visual contact with the ground when the airplane struck the ground. On impact, the undercarriage were torn off and the airplane slid in an open field before coming to rest few dozen meters short of runway. All eight occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
The crew descended below the MDA in marginal weather conditions.

Circumstances:
The pilot, sole on board, was completing a delivery flight from Wichita to France via Portland and Gander. The approach to Gander was initiated by night and good weather conditions. On final, the pilot descended too low when the twin engine airplane struck trees and crashed few km short of runway threshold. The aircraft was destroyed and the pilot was killed. Still owned by Cessna Aircraft, the airplane was on its way to France to be delivered to its future operator Flo Air.
Probable cause:
Improper IFR operation on part of the pilot who misjudged distance and altitude on final approach. The following factors were reported:
- High obstructions,
- Visual conditions,
- Dark night,
- No visual reference.

Circumstances:
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.
Probable cause:
It was determined that the crew was tired at the time of the accident and that the captain was on duty since 29 hours without sufficient rest time. Approach procedures negligences and poor crew coordination affected flight conditions. Difficult weather conditions with low clouds, snow falls and turbulences contributed to the difficulty of the flight conditions, as well as the fact that the copilot was inexperienced. It was reported he was recently promoted on B707 and this was his first approach following a six-week holiday period. Finally, the crew encountered technical issues with the generators on engines n°1 and 4 on final approach.
