What happened
During the final leg of its fifth flight sector of the day, the aircraft began its descent toward Inverness. Shortly after initiating the descent, the flight path became unstable, characterized by an unsteady rate of descent and a leftward turn. The wreckage was found in a state of extreme fragmentation, which indicated that the aircraft struck the ground while in a steep, left-hand spiral dive at an estimated speed of approximately 350 kt.
Findings
Investigators examined the wreckage and determined that there were no significant failures related to the engines or the primary airframe components. However, the investigation could not establish a definitive reason for the sudden transition into uncontrolled flight. Furthermore, the evidence did not show any signs that the crew attempted to recover the aircraft from the dive. Due to the lack of conclusive data regarding the deviation, the investigation emphasized the importance of flight recorder reliability, reiterating previous safety recommendations directed at EASA.
