## 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 a report indicating that cracks were found on the fuselage frame webs at stations forward and aft of the overwing emergency exits between stringers S-7 and S-8. This proposed AD would require repetitive high frequency eddy current (HFEC) inspections for cracking of the fuselage frame webs at certain stations between stringers S-7 and S-8 and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.
