AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
For certain airplanes, perform repetitive inspections of the clevis bushings on the inboard and outboard sequence carriages of the wing foreflap for bushing migration, and take corrective action if necessary. Replace existing bushings with new bushings to terminate repetitive inspections. Replace bushing markers with new markers, if necessary, to indicate correct bushing orientation. For other airplanes, perform a one-time inspection to determine bushing orientation and take follow-on actions as required.
