What the agency says
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by a report of cracks found in the fuselage skin underneath the aft drain mast. This AD requires repetitive inspections of the fuselage skin and structure common to the aft drain mast for any crack or corrosion and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
