Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This proposed AD was prompted by a report of fatigue cracking at certain frame tie rod locations of the wing. This proposed AD would require 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 proposing this AD to address the unsafe condition on these products.
