## Summary

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of cracks found in the main landing gear (MLG) beam forward support fitting. This proposed AD would require repetitive inspections for cracking of the MLG beam forward support fitting, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.
