Abstract
We are adopting a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-Trent 970-84 and RB211-Trent 972-84 turbofan engines. This AD requires an inspection of the drains mast. This AD was prompted by cracks found in the transition duct area of the drains mast. We are issuing this AD to address the unsafe condition on these products.
