## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-300, -400, and -500 series airplanes. This proposed AD was prompted by a report of fatigue cracking found in a certain fuselage frame common to the water tank support intercostal clip located between certain stringers. This proposed AD would require inspections for any cracking of a certain fuselage frame, and repair if necessary. We are proposing this AD to address the unsafe condition on these products.
