Airworthiness Directives; The Boeing Company Airplanes

Summary

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by a report indicating that the protection system on the left fan cowl of the right engine does not sufficiently cover the components and systems from possible cross engine debris. This AD requires performing a maintenance records check or inspection of the right engine to determine the part number of the left fan cowl and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
