What happened
The incident occurred during a cruise phase flight conducted under poor weather conditions. The twin-engine aircraft deviated from its intended path and impacted the terrain on the slope of Mt Skalafell, which is situated in the vicinity of Hellisheiði. The collision generated significant impact forces that resulted in the total destruction of the airframe. All four individuals aboard the aircraft were killed in the accident.
Findings
The available records indicate that the crash was precipitated by the interaction between the aircraft's trajectory and the mountainous terrain while operating in adverse meteorological conditions. The structural integrity of the aircraft could not withstand the forces generated during the ground impact, leading to the fatal outcome for all occupants.
