Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2019-01244

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by reports of warpage of internal engine fire handle components, which can cause binding and prevent proper operation. We are issuing this AD to address the unsafe condition on these products.
