## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, and -300 series airplanes. This proposed AD would require repetitive detailed inspections to detect discrepancies of the retaining pin lugs on the support fitting of the main landing gear (MLG) beam, and rework of the support fitting, or replacement of the fitting if necessary. This proposed AD is prompted by reports of discrepancies of the lugs. We are proposing this AD to prevent separation of the support beam of the MLG from the rear spar, which could cause cracking of the MLG support fitting and a consequent leak in the wing fuel tank or collapse of the MLG.
