## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2018-16-05, which applies to all The Boeing Company Model 757-200, - 200PF, -200CB, and -300 series airplanes. AD 2018-16-05 requires repetitive inspections for skin cracking and shim migration at the upper link drag fittings, diagonal brace cracking, and fastener looseness; and applicable on-condition actions. Since the FAA issued AD 2018-16-05, an operator reported finding multiple cracks in the drag fitting at fastener holes while inspecting for cracking as required by AD 2018-16-05. This proposed AD would retain the actions required by AD 2018-16-05, reduce the compliance times for certain inspections, and add repetitive inspections at certain fastener hole locations and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
