Loss of situational awareness after intrument failure cited in fatal Swedish CRJ-200 accident

12 December 2016

The fatal accident of a West Air Sweden CRJ-200 cargo plane in January 2016 was caused by the failure of an Inertial Reference Unit, which caused the captain’s Primary Flight Display to show unusual attitudes. The crew lost situational awareness as it was a dark moonless and cloudless night and both pilot’s flight displays showed opposite dirctions. A comparator caution was not shown due to the PFDs declutter function in unusual attitude. Loss of control followed and the aircraft impacted terrain.
