Accident

An aircraft crashed during a final approach to Honningsvåg-Valan Airport. The approach was conducted in marginal weather conditions. During the approach, the aircraft began to pitch up and down before entering a stall. The crew increased power, and the aircraft gained a small amount of altitude. It then stalled a second time and impacted terrain 150 meters short of the runway threshold.

Casualties

Both pilots and one passenger were killed in the accident. Twelve other occupants sustained injuries.

Investigation

An investigation was conducted into the accident. The probable cause was identified based on the official findings.

Probable Cause

The investigation determined that the crew completed the approach at an airspeed too low for the wind component and force present. Atmospheric turbulence and relatively strong winds existed along the approach path, and the crew failed to adjust the aircraft's speed accordingly. The relatively low experience level of the crew was considered a contributing factor.
