Geoffers, inside guy at Agusta....
Any more info on what caused the T/R gearbox to depart? Agusta's bulletin says consistent with FOD, but they could as easily have added that it was also consistent with a migrating undiscovered fatigue crack, or consistent with poor maintenance and someone forgetting to lock or safety wire something.
Outstanding airmanship by the pilot. I wonder if he had Rotorsim training and the training syllabus includes the tailrotor gearbox departing emergency, or whether he'd learned all his fine art at CHC.
