Circumstances:
Following an uneventful flight from Oslo, the crew started the descent to Copenhagen-Kastrup Airport in marginal weather conditions. The crew was cleared to descend to 5,000 feet then 1,500 feet when he was trying to intercept the ILS of runway 22L. On final, the four engine aircraft nosed down and plunged into the Øresund few hundred yards off the Saltholm Island. Rescuers were able to evacuate 3 passengers while 31 other occupants were killed. Three days later, one of the survivor died from his injuries.
Probable cause:
The probable cause of this accident was loss of control of the aircraft at the moment where the aircraft was about to intercept the ILS glideslope to runway 22L at Copenhagen airport, Kastrup.
Although it has not been possible to establish the cause of the loss of control, it is most likely to believe that the aircraft in the landing configuration was affected by a deterioration of the airflow over the tailplane to such a degree that longitudinal stability was lost.

Circumstances:
The aircraft departed Vaernes Airport, Trondheim, at 0830LT on a scheduled flight to Oslo, carrrying a crew of two and ten passengers. The aircraft entered clouds at 2,500 feet right after take-off and did not have visual contact with the ground thereafter. The copilot later stated that between Vaernes and Tolga when the aircraft reached cruising altitude, normal cruise power was set up but the resultant indicated airspeed was 20 knots below normal. The aircraft reported that at 0912 hours it had passed Tolga radio beacon at 8 000 feet (2,438 m), and that it was experiencing light icing. This was the last radio contact with the aircraft. From this point on it appears that the icing increased rapidly and the aircraft started to lose altitude, even though the de-icing system for wing and tail planes was in use. At 0925 hours it was decided to return to Vaernes Airport.The aircraft, when approximately abeam Tolga and to the east, altered its course 25 to 30 degrees northeast. This maneuver, carried out by the captain, was interpreted by the co-pilot to mean that he had decided to divert to Rhos. The controls were taken over by the copilot while the captain continued to try to establish radio contact with the ground on frequency 126,7 mc/s. No signals were picked up. At approximately 0950 hours the aircraft hit Hummelfjell at a height of approximately 1,350 metres. At the time of the crash the aircraft was in heavy fog, with cockpit window covered with ice to an extent which drastically reduced the crew's visibility. The force of the impact was somewhat reduced in that the aircraft touched down in a bowl in the terrain and made two bounces on the snow, which covered the mountain to a depth of 40 cm, before settling down. The captain and one passenger died instantly.
Probable cause:
The accident was due to the unusually heavy icing which the aircraft encountered. Severe downdraft immediately prior to the crash may have been a contributing factor.

Circumstances:
The crew was completing a flight from Oslo to Tromsø with an intermediate stop in Trondheim. On approach to the bay of Stjørdal, about 25 km east of Trondheim, the pilot in command encountered marginal weather conditions with strong cross winds. Upon landing on rough sea, the seaplane bounced and hit violently the water surface. The fuselage broke in two, causing the front section including the cockpit to separate from the rest of the aircraft. Sixteen passengers and three crew members were killed.

Circumstances:
The three engine aircraft christened 'Herman Stache' left Copenhagen Airport at 1750LT bound for Oslo. After passing Skagen, the aircraft entered over Skagerrak and the weather conditions deteriorated. Due to poor visibility and wind from the east, the aircraft diverted from the prescribed flight path to the west. Persuaded to be on the correct track for Oslo, the crew reduced his altitude and went through the cloud layer to start the descent to Fornebu Airport. At an altitude of 1,355 meters, the aircraft hit the slope of Mt Skorvefjell located northwest of Seljord. The wreckage was found few hours later and all 15 occupants were killed.

Probable cause:
It was concluded that the accident resulted from a controlled flight into terrain. At the time of the accident, the aircraft was off the prescribed flight path, most probably due a wind from the east gusting up to 15 km/h. Also, the radio equipment failed in flight, which should be considered as a contributory factor.

The crew of a ship was quickly on the scene and was able to rescue eleven passengers while all nine other occupants, among them all three crew members, were killed. The aircraft was lost.
Probable cause:
It was determined that a signal flare accidentally activated in the cockpit, spreading smoke and forcing the crew to ditch the aircraft.
