The U.S. Marine Corps has determined that the crash of a MV-22B Osprey, call sign “Ghost 31”, in Norway on Mar. 18 was due to pilot error.
The mishap aircraft was flown beyond its angle-of-bank limit and hit the ground. Investigators also determined that the aircrew had deviated from the preplanned and authorized flight and entered the Gråtådalen Valley at low-level.
The mission that day calls for the crew to flew south of Bodø. There was no requirement for the flight to navigate through the Gråtådalen Valley at low altitudes.
The aircraft impacted the valley’s eastern side at approximately 4:23 p.m. local time. Data from the flight indicated a left turn at 68 degrees angle-of-bank followed by an overcorrected maneuver with a right turn in excess of 80 degrees. This cost the aircraft to lose altitude and airspeed. It was not known who was at the controls before the crash.
