Airworthiness Directive · Amendment 39-22657 · Fuselage
The Boeing Company Airplanes
This AD applies to The Boeing Company Model 737-600, 737-700, and 737-800 series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 737-53A1217, Revision 1, dated September 8, 2022.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, 737-700, and 737-800 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating the fuselage skin repairs at the double row of fasteners centered on certain stringers have inadequate inspection requirements for continuing airworthiness following repair accomplishment. This AD is intended to complete certain programs to support the airplane reaching its limit of validity (LOV). This AD requires repetitive inspections for cracks of skin repairs at Stringer S-17, and corrective actions if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: For Group 1 through 3, Configuration 3 airplanes as identified in Boeing Alert Service Bulletin 737-53A1217, Revision 1, dated September 8, 2022, at the applicable times specified in Tables 3 through 6 of paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 737-53A1217, Revision 1, dated September 8, 2022, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin 737-53A1217, Revision 1, dated September 8, 2022.
(1) Where Boeing Alert Service Bulletin 737-53A1217, Revision 1, dated September 8, 2022, specifies contacting Boeing for repair instructions or for alternative inspections: This AD requires doing the repair, or doing the alternative inspections and applicable on-condition actions, using a method approved in accordance with the procedures specified in paragraph (i) of this AD.
(2) Where Boeing Alert Service Bulletin 737-53A1217, Revision 1, dated September 8, 2022, specifies using corrosion inhibiting compound (CIC) compound BMS 3-23, this AD also allows use of CIC compound BMS 3-35.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
