## 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 in the lug root radius of a main landing gear (MLG) aft hanger link lug fitting. This proposed AD would require surface high frequency eddy current (HFEC) inspections of the left and right side MLG aft hanger link lug fitting for cracking, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
