Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2020-03964

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by a report of fatigue cracking at certain frame tie rod locations of the wing. This AD requires repetitive inspections for cracking of the left- and right-side frame tie rod assemblies and stub beam upper chords, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
