Circumstances:

On final approach to Mineralnye Vody Airport by night, the crew encountered poor weather conditions. At a speed of 290 km/h, flaps were deployed at an angle of 30°, causing the airspeed to drop to 260 km/h. At a distance of 1,500 metres from the runway threshold, the captain decided to initiate a go-around as he was unable to establish a visual contact with the runway. During initial climb, at an altitude of about 90 metres, the airplane entered a right turn then rolled to the right at an angle of 15-30° and adopted a critical angle of attack of 15-18°. The tail stall and the airplane crashed in flames 2 km south of the airport. A crew member and 76 passengers were killed while 21 other occupants were injured. The aircraft was destroyed.

Probable cause:

Failure of the crew to adopt a proper go-around configuration after a missed approach. The loss of control during initial climb was the result of a premature raise of the flaps, which caused the aircraft to reach a critical angle of attack and to stall.

Circumstances:

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.

Probable cause:

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.
