Required Actions
Inspect the outer surface of main landing gear cylinders (P/N 528002 or P/N 528402) and fulcrum arms for cracks using magnetic particle, dye penetrant, or approved methods. If cracks are found, rework cylinders per approved method or replace with inspected/crack-free cylinders. For reworked cylinders, record rework details, limit use to aircraft below 55,000 lbs take-off weight, and reinspect every 1,000 hours time in service. If no cracks and less than 14,000 hours time in service, reinspect before 15,000 hours. If over 14,000 hours, reinspect every 1,000 hours.
