Airworthiness Directives; General Electric Company Turbofan Engines

We are adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-2B67, -2B67B, and -2B67/P turbofan engines. This AD was prompted by low-cycle fatigue (LCF) cracking of the fuel manifold leading to an engine fire. This AD requires removal from service of certain fuel manifolds at the next engine shop visit and their replacement with parts eligible for installation. We are issuing this AD to address the unsafe condition on these products.
