The crew was last in contact with the air traffic services at Longyearbyen at 15:06 hours, and were then instructed to contact the helicopter base. The helicopter was reported missing at 15:30 hours to the AFIS Longyear. The helicopter was later found at 209 meters depth approximately 2 km off the coastline northeast of the helicopter base.

The helicopters body, tail, Cockpit Voice Recorder (CVR) and GPS units was recovered 4 November. The Flight Data Recorder (FDR) had been separated from the helicopter and was found severely damaged and without the memory unit one day later. Based on the condition of the recovered parts of the FDR, it was decided the following day to discontinue the special search for the memory unit. Neither the FDR nor the CRV were equipped with Underwater Location Beacons (ULB).

The CVR and the GPS-units have been transported to Moscow by the AIBN in cooperation with Russian MAK (Interstate Aviation Committee) for downloading and analysis. All audio files have been downloaded, including the one from the helicopters last flight. Frequency analysis has been performed to investigate any possible technical errors in rotating components. The analysis has not indicated that such errors were present. Only one of the two GPS units contained data from the last flight such as speed, altitude and track.

The helicopter has been transported to Hammerfest and transferred to another vessel for transportation to Stavanger, were further investigation has been conducted in cooperation with the IAC and the helicopter manufacturer.

The results from the investigation of the helicopter, CVR and GPS units have been gathered and supplied with further information from interviews, weather conditions, operative regulations, company policies and other information.

Eight persons were onboard. The helicopter was not equipped with floatation gear or life raft, but there were life jackets for the passengers. They were not used. No persons were found in the helicopter. One person has been recovered from the seabed.
