A malfunction in one of the inertial reference units had produced erroneous attitude indications on one of the instrument displays. The crew's subsequent response resulted in spatial disorientation, leading to the loss of control of the aircraft.[1][2][3] Aircraft and crewThe aircraft was built in 1993 and was operated by Lufthansa CityLine as D‑ACLE until the end of 2006. It had a manufacturer's serial number (MSN) of 7010 and had two General Electric CF34-3B1 engines.[3] The aircraft then underwent a cargo conversion re‑designating it as a CRJ200-PF (Package Freighter). The aircraft had been operated by West Air Sweden since 2007 as SE‑DUX.[4] At the time of the crash, it had accumulated more than 38,600 flight‑hours in more than 31,000 cycles.[5] The 42‑year‑old Spanish captain had around 3,200 flying‑hours, of which 2,016 were on this aircraft type; the 33‑year‑old French first officer had 3,050 flying‑hours, of which 900 were on this aircraft type.[3] Flight{{Location map many| Norway | width = | float = | border = | caption = Map of Norway with location of the crash site, between the departure airport (Oslo) and intended destination (Tromsø). | alt = caption | relief = | AlternativeMap = | | label1 = Oslo | label1_size = | position1 = | background1 = | mark1 = City locator 9.svg | mark1size = 10 | link1 = | lat1_deg = 60 | lat1_min = 12 | lat1_sec = 10 | lat1_dir = N | lon1_deg = 11 | lon1_min = 05 | lon1_sec = 02 | lon1_dir = E | | label2 = Tromsø | label2_size = | position2 = | background2 = | mark2 = City locator 9.svg | mark2size = 10 | link2 = | lat2_deg = 69 | lat2_min = 40 | lat2_sec = 53 | lat2_dir = N | lon2_deg = 18 | lon2_min = 55 | lon2_sec = 4 | lon2_dir = E | | label3 = Crash site | label3_size = | position3 = | background3 = | mark3 = Airplane_silhouette.svg | mark3size = 10 | link3 = | lat3_deg = 67 | lat3_min = 43 | lat3_sec = | lat3_dir = N | lon3_deg = 16 | lon3_min = 54 | lon3_sec = | lon3_dir = E }} The aircraft departed Oslo-Gardermoen Airport at 23:11 hours local time for a flight to Tromsø Airport. The aircraft carried 4.5 tonnes ({{convert|4.5|t|kg|disp=out}}; {{convert|4.5|t|lb|disp=out}}) of mail. While in cruise at Flight Level 330 and at approximately 23:31, the aircraft transmitted a Mayday call before communication and radar tracking were lost by air traffic control. Aircraft tracking service Flightradar24 reported that the aircraft lost 6,485 metres (21,275 ft) in altitude over a period of 60{{nbsp}}seconds ({{convert|{{#expr:(33000-11725)/60}}|ft/s|km/h|0|disp=out}}; {{convert|{{#expr:(33000-11725)/60}}|ft/s|mi/h|0|disp=out}}) at 00:18, based upon data transmitted by the aircraft's transponder.[6] SearchBoth Norwegian and Swedish authorities searched for the aircraft, discovering the wreckage at 03:10 in the morning. The crash site was located at an elevation of {{convert|1000|m}} in a remote area near Lake Akkajaure, approximately {{convert|10|km}} from the Norwegian border. The aircraft remains were spread in a circle approximately {{convert|50|m}} in diameter, which was said to suggest a high‑energy impact.[7] InvestigationThe Swedish Accident Investigation Authority ({{lang-sv|Statens Haverikommission}}, or SHK) opened an investigation into the crash.[8] On 9 January 2016, the flight data recorder (FDR) was found severely damaged as well as parts of the Cockpit Voice Recorder (CVR). The unit was, however, not intact, and the part containing the memory functions was missing. The following day, the missing parts of the CVR were found, alongside human remains.[9][10] On 12 January, SHK reported that the distress call from the pilots contained the word "Mayday" repeated, with no further information. On 26 January, Statens Haverikommission reported that they had managed to read both CVR and FDR, and were analysing and validating the recordings.[7] On 19 March, in their interim report, SHK revealed:
The final report was published by SHK on 12 December 2016.[12] The inquiry reached the following conclusion: The accident was caused by insufficient operational prerequisites for the management of a failure in a redundant system.
