Airworthiness Directives; The Boeing Company Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757-200, 757-200CB, and 757-300 airplanes. This AD was prompted by cracks on both sides of the airplane in the station (STA) 1640 frame web between S-14 and S-15. This AD requires an inspection or maintenance records check for existing liner holes in the STA 1640 frame web between S-14 and S-15, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
