[edit] Final moments
The airplane, a Vickers 838 Viscount, was at an altitude of 1,150 feet and was descending to land at the Stockholm-Bromma Airport (BMA/ESSB), serving Stockholm. Suddenly, the aircraft experienced a loss of pitch control. The aircraft went into a steep dive and crashed into the residential area of Kälvesta, five km short of the runway. The aircraft impacted a car park, and no one on the ground was killed. All 19 passengers and 3 crew members on board the airplane were killed. One of them was the well-known table tennis player Hans Alsér.
[edit] Investigation
A full investigation into the cause of the accident was conducted by the Government of Sweden. The investigation came to the following conclusions:
The aircraft had been cruising for a long period with the number two and number three engines at a low power setting. This meant that the anti-icing systems run from the engines were not at a temperature sufficient for them to operate correctly. As a result, ice built up on the stabilizer, which disrupted the airflow, causing the loss of pitch control when the flaps were being fully extended on final approach.
