## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-8 and 747-8F series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the skin lap joints at certain stringers are subject to widespread fatigue damage (WFD). This proposed AD would require modifying the left and right side lap joints of the fuselage skin, repetitive post-modification inspections for cracking, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
