## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by a report indicating that during a fleet survey on a retired Model 737 airplane, cracking was found common to the windshield and aft sill web. This proposed AD would require, at certain locations, repetitive high frequency eddy current (HFEC) inspections of the windshield and aft sill web, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.
