The aircraft was completing a regular schedule flight from Kristianstad to Stockholm-Bromma with intermediate stop in Växjö and Jönköping, carrying 19 passengers and a crew of three on behalf of Linjeflyg. On approach to Bromma Airport, the crew encountered marginal weather and icing conditions. At an altitude of 1,150 feet and a speed of 137 knots, flaps were deployed at an angle of 40° when control was lost. The airplane entered a nose down attitude and crashed at an angle of 110° and a speed of 210 knots in a parking lot located in the residential area of Kälvesta, about 4,5 km short of runway 12 threshold. The aircraft was totally destroyed by impact forces and a post crash fire and all 22 occupants were killed. At the time of the accident, weather conditions were considered as marginal with icing conditions and a horizontal visibility of 5 km with a cloud base at 700 feet.
Loss of control on final approach due to an excessive accumulation of ice on the horizontal stabilizers after the crew lower the flaps from 32° to 40°. When control was lost, both right engines n°3 and 4 were not running at full power for undetermined reasons, which caused the deicing system to produce an insufficient temperature.
