Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2020-21-17, which applies to all The Boeing Company Model 757 airplanes. AD 2020-21-17 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 2020-21-17, a determination has been made that the compliance times for certain groups are not adequate. This proposed AD would retain the requirements of AD 2020-21-17 with reduced compliance times for certain airplane groups. The FAA is proposing this AD to address the unsafe condition on these products.
