Unsafe Condition

Reports of cracked outer V-blade fittings at the hinge beam end of Rolls-Royce engine thrust reversers, on airplanes on which the optional terminating action was done, could result in separation of a thrust reverser from the airplane during normal reverse thrust or during a refused takeoff, leading to unexpected thrust asymmetry and a possible runway excursion.

Required Actions

For airplanes on which the optional terminating action was done, perform repetitive inspections for cracking in the outer V-blade fittings of the hinge beam and latch beam ends of each thrust reverser half. Replace an affected thrust reverser half if necessary.
