Airworthiness Directive · Amendment 39-22935 · Fuselage
The Boeing Company Airplanes
(1) This AD applies to all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes, certificated in any category.
(2) Installation of Supplemental Type Certificate (STC) ST01219SE does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01219SE is installed, a “change in product” alternative method of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17.
The FAA is 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 indicating cracks in the frame inner chord and web at station (STA) 727. This AD requires an inspection for any repair installed, repetitive inspections of the frame inner chord and web at STA 727 for any crack, and applicable on- condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
For airplanes identified as Group 1 in Boeing Alert Requirements Bulletin 737-53A1416 RB, dated July 21, 2023: Within 120 days after the effective date of this AD, inspect for existing repairs and cracking of the frame inner chord and web at STA 727, between S-11 and S-13, left and right sides, using a method approved in accordance with the procedures specified in paragraph (j) of this AD.
For airplanes identified as Group 2 in Boeing Alert Requirements Bulletin 737-53A1416 RB, dated July 21, 2023: Except as specified by paragraph (i) of this AD, at the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 737-53A1416 RB, dated July 21, 2023, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 737-53A1416 RB, dated July 21, 2023.
Note 1 to paragraph (h): Guidance for accomplishing the actions required by this AD can be found in Boeing Service Bulletin 737-53A1416, dated July 21, 2023, which is referred to in Boeing Alert Requirements Bulletin 737-53A1416 RB, dated July 21, 2023.
(1) Where the Compliance Time columns of the tables in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 737-53A1416 RB, dated July 21, 2023, refers to the original issue date of Boeing Alert Requirements Bulletin 737-53A1416 RB, this AD requires using the effective date of this AD.
(2) Where Boeing Alert Requirements Bulletin 737-53A1416 RB, dated July 21, 2023, 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, before further flight using a method approved in accordance with the procedures specified in paragraph (j) of this AD.
