Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2022-07903

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by a report from Boeing that Rolls-Royce Deutschland Ltd & Co KG (RRD) discovered a design issue in the engine fuel feed system, which could result in fuel flow restrictions to both engines when ice that has accumulated in the airplane fuel feed system suddenly releases into the engines. This proposed AD would require revising the existing airplane flight manual (AFM) to update the limitations on minimum fuel temperatures. The FAA is proposing this AD to address the unsafe condition on these products.
