Confidence Rating: Accident investigation report completed and information captured
Linjeflyg flight 618 originated at Kristianstad (KID) with stops at Växjö (VXO) and Jönköping (JKG) en route to Stockholm (BMA) in Sweden. On the final leg of the flight, while on approach to Stockholm-Bromma Airport, the aircraft suddenly pitched down from an altitude of 1150 feet. It went into a vertical dive and crashed on a parking lot in the Kälvesta neighbourhood.
Because the no. 2 and no. 3 engines had been running with reduced power for a long time, the anti-ice system temperature was too low.

Probable cause (translated from Swedish):
The accidnt was caused by the stabilizer stalling due to the air flow around it being disturbed by ice accretion.

The reason why ice was formed is that the de-icing system's temperature had been too low due to insufficient power on engines 2 and 3 for a long time. This can be attributed to deficiencies in the pilot's flight manual regarding the operation of the de-icing system, which, in turn, should be due to deficiencies in the flight manual of the manufacturer's aviation authority. Insufficient information in the pilot's flight manual on the effects of ice formation on the stabilizer may also have affected. The pilots have also not been informed of the occurrence of severe ice formation in the Stockholm area.
