The buckling of the MRB LE protection at approx. 1/3 of the span of the MRBs still concerns me, it’s not evident on the L2 incident. Did the massive overpitch occur as a result of the failure or the cause of it?

The Main rotor flight controls run under the No2 Engine (grandfather design rights). Power turbine disk intrusion has been addressed allegedly by contained blade shedding. Gas generator turbine disk failure has not been looked at.
