## Abstract

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by a report of cracks in a certain body station (STA) frame web and doubler at fastener holes common to the stop fitting at a certain stringer. This AD requires repetitive surface high frequency eddy current (HFEC) inspections for cracking of the frame web and doubler at the stop fitting at a certain stringer, and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.
