TRF4EV3R
SHK has concluded there is something wrong with pitch, roll, heading data. FDR data shows values that would not correspond to the actual movement of the airplane. To further investigate this they need to recover instruments et al from the wreckage to study witness marks or other possible signs (knob positions) of what may have malfunctioned.
Right now the wreckage is frozen into what I would describe as a temporary glacier kind of environment. The snow on the impact point was very solid and melted temporarily when the aircraft struck. It then re-froze and to retrieve items from it would need special equipment. Problem is, this area is so remote there are no roads and the only way in during snow season is by snow mobile or helicopter. Obviously you can not transport heavy machinery on either of these transportation modes so we need to wait until spring when the snow melts. This would possibly mean May or even June, so until then there are few possibilities of recovery of important instruments.
Last thing I read about this was in Norwegian media (nrk.no) the 8th of March.
