AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect each auxiliary emergency exit door shear pin fitting assembly by x-ray within 500 landings after the effective date and thereafter at intervals not exceeding 4,000 landings or one year, whichever comes first. Replace any cracked assembly prior to further flight. New assemblies must be initially inspected before 20,000 landings after installation and subsequent inspections at intervals not exceeding 4,000 landings or one year. Modification via Service Bulletin 52-117, R1, or FAA-approved revisions terminates repetitive inspections.
