155° outbound from Advent. During this turn, a malfunction in the electric trimming mechanism caused the piloting pilot to deactivate the aircraft flight control systems' servogear in the pitch channel at 08:15:58. This was again activated at 08:16:42 UTC. At 08:17:08 UTC, the crew started the turn to bring the aircraft to 300° magnetic inbound; however, the lateral deviation from the outbound magnetic course was 155°, or to the left. At 08:17:57 UTC, the navigator said "Ah, abeam eight miles 2801 inbound", to which AFIS replied two seconds later "Correct". This was the last radio communication between the crew and Longyear. At 08:18:30 UTC, the piloting pilot turned off the autopilot pitch channel. For the rest of the flight, the plane continued with autopilot only in roll. Following the aircraft passing through the localizer centerline and having rolled out on 290°, a discussion arose among the crew if the turn had been made at the right time. The initial comment about this was made by the first officer at 08:19:06 UTC. This resulted in a roll out of the turn to final approach and corrective turn to magnetic heading 306°. At this time, the aircraft was from the airport and right of the centerline at with an airspeed of . Instead of intercepting the centerline, the crew continued to track on the right side, nearly paralleling the localizer course. At 08:20:17 UTC, the pilot in command ordered the aircraft turned to 291°, which, when adjusted for drift, resulted in a course close to 300°. At this time, the aircraft had a lateral deviation from the approach centerline of . The aircraft started descending at 08:20:24 UTC. A corrective turn was made at 08:21:13 UTC and completed 11 seconds later at magnetic heading 300°. At the time, the aircraft was descending . The aircraft started turning left at 08:22:05 UTC, and immediately entered an area of turbulence created by the surrounding mountains. During initial approach, the radio altimeter warning had been activated several times, which indicated less than from the aircraft to the terrain. During final approach, the ground proximity warning system was activated nine seconds before impact, which lasted until impact. Six seconds before impact, the radio altimeter warning was activated. At 08:22:23 UTC (10:22:23 local CEST) the aircraft collided with the top of Operafjellet at elevation, located from Svalbard Airport and right of the approach centerline. The aircraft was
