Circumstances:
On final approach to Oskarshamn Airport following an uneventful flight from Stockholm-Arlanda Airport, the crew selected flaps down when the aircraft pitched up. The tail stalled then the aircraft rolled to the left, entered a dive and crashed 150 meters short of runway 19 and 75 meters to the left of its extended centerline. The aircraft was totally destroyed by impact forces and a post crash fire and all 16 occupants were killed.
Probable cause:
The accident was probably caused by the fact that the pilot could not compensate for the rapid pitch-up that occurred when the wing flaps were selected out while the engines were running at high power.
The following contributing factors were reported:
- The aircraft was extremely tail-heavy,
- The crew's training and overall experience on the aircraft type was limited.

Circumstances:
After takeoff from Örnsköldsvik Airport, while climbing to an altitude of 7,000 feet, the left engine oil pressure warning light sounded. The crew shut down the engine but was unable to feather the propeller. Doing so, a fuse blew and only the right side of the instrument lights remained functional. After being cleared to return, the crew completed a turn but on approach, he was forced to use full elevator and rudder deflection because the left propeller could not be feathered. Misaligned, the aircraft landed 30 meters to the left of the runway then rolled few dozen meters before coming to rest. All 17 occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Because the left propeller could not be feathered, this created drag the the crew was forced to compensate with trim and rudder deflection, causing the aircraft to be misaligned on final approach.
The following contributing factors were reported:
- An oil leak in the left engine during initial climb forced the crew to shut it down,
- Power supply problems caused by the left side not having been isolated from the right side,
- Wrong adjustment of the speed control trigger,
- Inadequate following of the checklist.

Circumstances:
On final approach to Falköping Airport, both engines failed simultaneously. The pilot attempted an emergency landing when the aircraft crashed in an open field located five km short of runway. The aircraft slid for few dozen meters and eventually collided with a stone wall. The pilot was slightly injured and the aircraft was damaged beyond repair.
Probable cause:
It was determined that both engines failed following a fuel exhaustion. The main tanks and those in the wings were empty while the tip tanks still contained fuel. The left auxiliary fuel pump had been changed the day before the accident. The pilot proceeded to the daily inspection but failed to drain the fuel system. The main tank was extremely dirty and the filters in the fuel transfer lines were fitted against the published procedures and were also blocked by impurities. Additionally, those filters contained a lot of water. In all lines, the fuel was so contaminated that electrical resistance caused the fuel gauges to indicate a quantity of fuel far greater than reality. Investigators at the scene of the accident found that the main tank drain valve was open.

Aircraft flight hours:

Circumstances:
The twin engine aircraft was engaged in a charter flight from Hagfors to Oslo-Fornebu, carrying four passengers and two pilots. During the takeoff roll on runway 18, at a speed of 95 knots, the crew realized he could not takeoff and decided to abandon the takeoff procedure and initiated an emergency braking maneuver. Unable to stop within the remaining distance, the aircraft overran, struck the localizer antenna and came to rest 200 meters further. All six occupants were rescued and the aircraft was damaged beyond repair.
Probable cause:
It was determined that the aircraft went out of the hangar few minutes prior to takeoff and has been deiced, except for the underwings. Weather was poor at Hagfors Airport with heavy snow falls and a certain quantity of snow accumulated on the upper wings and the fuselage between the time the aircraft has been towed out from the hangar and the takeoff procedure. It is believed that the aircraft was unable to gain sufficient speed for takeoff due to snow accumulation on upper wings and a probable accumulation of freezing rain on the underwings. Also, the runway surface was covered with snow and the braking action was poor when the crew initiated an emergency braking procedure.

Parked at Saldus Airport, Latvia, the single engine aircraft was stolen by a Soviet pilot who wanted to fly to Sweden. He was able to leave the Soviet Airspace and while approaching Gotland Island, he ditched the aircraft few dozen meters offshore. He was able to swim to the shore, was rescued and requested political asylum. The aircraft was recovered and later transferred to the Gotland Förvarsmuseum.

Circumstances:
Immediately after liftoff from runway 08, while climbing to a height of about 10 meters, the aircraft pitched down. The copilot confirmed that the airspeed value and the engine indications were normal. The airplane was continuing to 'float' above the runway and the captain decided to land back. The aircraft landed hard on its nose gear and bounced. The second touchdown was completed on both main gears but hard again, causing them to penetrate the wings and the fuel tanks, causing the fuel to spill. Out of control, the aircraft slid for about 300 meters then veered off runway to the left and came to rest in a snow covered field, bursting into flames. All 27 occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
The perception of an unusual climb configuration due to various disturbances forced the crew to abort the takeoff procedure. The following contributing factors were reported:
- An incorrect movement of the pitch immediately after liftoff,
- The presence of nitrogen in the hydraulic lines may affected rudder movements,
- A possible accumulation of ice/snow on the top of the stabilizers may affected the aircraft stability and controllability.
