Airworthiness Directive · Amendment 39-23088 · Fuselage
The Boeing Company Airplanes
(1) This AD applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, certificated in any category.
(2) Installation of Supplemental Type Certificate (STC) ST00830SE does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST00830SE 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 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by a report of a frame web crack at a certain fuselage station (STA) between certain stringers common to the frame web notch. This AD requires repetitive inspections for cracks of the frames and repair of cracks. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 737-53A1410 RB, dated October 11, 2023, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 737-53A1410 RB, dated October 11, 2023.
Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 737-53A1410, dated October 11, 2023, which is referred to in Boeing Alert Requirements Bulletin 737-53A1410 RB, dated October 11, 2023.
(1) Where the “Boeing Recommended Compliance Time” column in the table under the “Compliance” paragraph of Boeing Alert Requirements Bulletin 737-53A1410 RB, dated October 11, 2023, refers to “the Original Issue date of Requirements Bulletin 737-53A1410 RB,” this AD requires using the effective date of this AD.
(2) Where Boeing Alert Requirements Bulletin 737-53A1410 RB, dated October 11, 2023, specifies contacting Boeing for repair instructions, this AD requires doing the repair using a method approved in accordance with the procedures in paragraph (i) of this AD.
