FAA 2024-03-06

Supersedes but retains requirements of AD 2021–20–13, which mandated repetitive lubrication and repetitive detailed visual inspections and non-destructive test inspections of the main landing gear shock strut lower pins and, if necessary, replacement. Updated AD introduces a terminating action for these repetitive tasks by replacing the main landing gear trailing arm bushing and installing new dynamic joint components. Prompted by a new design solution for this potential failure of the shock strut lower pin.
