S92 tail rotor pitch change shaft failure (?)!
Has this been confirmed somewhere and / or is there more info?
Haven't seen any written info yet, it's suspected that oil leaked from the TR gearbox into the shaft which is supposed to be filled with grease lubricant, the grease might then have been washed out by the oil, things got very hot, and the shaft snapped, and left the crew with no TR control. No parts fell off, and no bad vibrations as far as i know, but I wasn't there....
