Circumstances:
After liftoff from runway 24 at Oslo-Fornebu Airport, while climbing to a height of 30 feet at a speed of 140 knots, the stall warning activated. The captain decided to land but the remaining distance of 1,100 meters was insufficient. Unable to stop, the aircraft overran and plunged into the bay. All 33 occupants were quickly rescued while the aircraft was damaged beyond repair.
Probable cause:
Investigations were able to determine that the speed of the aircraft was correct but that the stall warning light was triggered following an error on the computer that misinterpreted some parameters transmitted by the Pitot tubes. It was reported that the aircraft suffered false stall warnings a couple of times during the past few days.

Circumstances:
Following an uneventful flight from Ålesund, the crew started a night approach to runway 06 at Oslo-Fornebu Airport. During the descent in limited visibility due to the night and fog, the captain and the approach controller exchanged several messages of sympathy for Christmas. 13 seconds after passing 3,500 feet, the airplane descended 1,510 feet below the MDA. In a gear and flaps down configuration, the airplane struck tree tops and crashed in flames in a dense wooded area located about 16 km west of the airport. The aircraft was totally destroyed and only five passengers survived the crash while 40 other occupants were killed, among them all three crew members.
Probable cause:
The probable cause of the accident was incorrect navigation under a truncated instrument approach to runway 06 at Fornebu Airport. For reason that could not be determined with certainty, the aircraft descended well below the MDA and was off course by 2,5° at the time of the accident. The following factors were reported:
- The second ADF was probably tuned on a false frequency by mistake,
- It is possible that interferences has occurred with the ILS which may have transmitted wrong information to the aircraft,
- The captain did not have a rest period in accordance with legislation,
- The captain exchanged messages with ATC that were not authorized during the initial approach,
- The control tower bearing indicator was moved from its fixed position in the control desk, so that the possibility of random directional control was reduced.

Circumstances:
The aircraft was completing a flight from RAF Wittering to Tromsø, carrying a Harrier load. After touchdown on a runway covered with slush, the airplane deviated to the left. The Aircraft Captain, without saying 'he had control' feathered the two starboard engines. The co-pilot, believing he was still in control, applied right rudder and brakes. Instead of a gentle correction to the centreline, the aircraft swung hard right and left the runway. As it crossed over the 'monnie' drain the cockpit area of the fuselage broke off by the crew door, coming to rest at an angle to the main fuselage, the tail also broke off. At this stage the crew 'legged it' through the flight deck windows leaving everything still switched on and live! The passenger had trapped his hand on the 'towel rail' when it folded under the impact, the navigator gave him a 'whack' which loosened his hand but broke his fingers.On hitting the ground outside the aircraft, the ALM had a heart attack (non-fatal). The main fuselage was covered in dirt which had entered through the break and if the ALM and pax had been sitting there they would have been killed. The Load remained 'nailed to the floor' and not one bottle was broken!

Probable cause:
At the Board of Enquiry everyone, apart from the Navigator, was found guilty of negligence, both pilots for lack of coordination, the engineer for leaving the frame live and the ALM for not being at his correct position for landing.

Circumstances:
Prior to departure from Bardufoss to Stokmarknes, the crew was informed about the poor weather conditions en route and the captain was instructed to continue directly to Bodø. Despite these instructions, he decided after takeoff to fly to Stokmarknes. While in cruising altitude, the crew encountered poor weather conditions with low clouds, fog and rain falls when the airplane struck the slope of Mt Lille Tussen (800 meters high) located on the Grytøya Island, about 75 km northeast of the Stokmarknes-Skagen Airport. The wreckage was found 20 meters below the summit and all 17 occupants were killed.
Probable cause:
The accident was the consequence of a controlled flight into terrain that occurred in poor weather conditions consisting of low clouds, fog and rain falls. For unknown reason, the captain decided to fly to Stokmarknes despite the instructions received prior to departure. It was determined that the night before the flight, the captain had a party and failed to observe sufficient rest time. It was also reported that the captain's blood showed an alcohol concentration estimated between 1 and 1,5‰.
