What happened
The incident occurred during the initial climb phase shortly after departure from Oslo-Fornebu Airport. The flight crew reported a malfunction with the left engine to ground control and decided to execute an immediate return. While maneuvering for the final turn, the aircraft lost altitude and collided with tree tops before impacting the ground in a forested section of Snarøya, situated southwest of the airport.
The crash resulted in significant casualties among those on board. Thirteen occupants were killed in the accident, while one passenger sustained serious injuries. The deceased included notable figures from the literary community, though specific identities are not detailed in this summary beyond the general context of the event.
Findings
Official investigations identified the primary factor leading to the accident as an engine failure. This mechanical issue prompted the crew's decision to return to the airport, but the subsequent loss of height during the approach phase proved fatal.
