Circumstances:

After touchdown on runway 19R at Oslo-Gardermoen Airport, while decelerating to a speed of 60 knots, the aircraft deviated to the right. At a speed of 40 knots, it impacted a snow berm then rotated to the right and came to rest in deep snow with its both propellers and the nose damaged. All 11 occupants evacuated safely while the aircraft was considered as damaged beyond repair.

Probable cause:

Comprehensive technical examination of the nose wheel steering on OY-NPB uncovered no single causal factor, but some indications of unsatisfactory maintenance. Irregularities that alone or in combination could have caused a temporary fault with the steering were present. The Accident Investigation Board believes that a temporary fault caused the nose wheel to unintentionally lock itself in a position towards the right. No other defects or irregularities that could explain why the aircraft veered off the runway were found. The AIBN reported that the same fault had occurred 6 days earlier as well, during that encounter the captain managed to disconnect nose wheel steering quickly enough to regain control. Maintenance could not replace the fault and the aircraft was released to service.

Circumstances:

The aircraft was completing a cargo flight to Bergen, carrying one pilot and 1,389 kilos of newspapers. Following a night takeoff from runway 19, while climbing in poor weather conditions at an altitude of about 390 metres, the single engine aircraft stalled and crashed in a wooded area located 1,5 km from the airport. The pilot, sole on board, was killed.

Probable cause:

The accident was the consequence of a stall during initial climb to an excessive accumulation of ice on wings and tail as the aircraft had not been deiced prior to departure. The following contributing factors were reported:
- The plane was outdoors for an estimated time of 20 minutes under conditions in which ice could adhere on the surface of the plane's hull, wings and tail surfaces.
- The plane was not de-iced by the pilot prior to departure.
- The company had not developed adequate written instructions for de-icing. The company had no written instructions to prevent icing during ground stay.
- The company had no sufficient equipment available, or added conditions sufficiently organized so that icin accretion be prevented or removed before departure from Gardermoen.
- The plane took off with ice on the surface of the wings and tail surfaces
- Ice on the surface of the wings and tail surfaces reduced flight characteristics in such a degree that the pilot did not manage to gain height after departure and therefore crashed.

Circumstances:

The approach to Oslo-Gardermoen Airport was started in poor weather conditions with low visibility due to fog. While descending at an altitude of 2,030 feet, the aircraft hit tree tops and crashed in a dense wooded area located on the east slope of Mt Mistberget, about 10 km north of the Gardermoen Airport. The aircraft was destroyed, three crew members were killed (both pilots and the flight engineer) while all other occupants were injured, some of them seriously.

Probable cause:

The descent was started prematurely, causing the aircraft to fly under the minimum safe altitude when it hit the slope of the mountain. It is considered that the accident was the result of a controlled flight into terrain, and that the crew inexperience and some radio range equipment deficiencies were considered as contributory factors.
