AD 2025-15-01 Airworthiness Directives; The Boeing Company Airplanes
Models named: 737-600, -700, -700C, -800, -900, -900ER series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
(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.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
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.
Unsafe condition
This AD was prompted by a report of a frame web crack at fuselage station 328 between stringers S-20R and S-21R common to the frame web notch. The FAA is issuing this AD to address undetected cracks in the frame. The unsafe condition, if not addressed, could lead to the inability of the principal structural element to sustain limit loads, which could result in the subsequent loss of structural integrity of the airplane.
Affected ADs
None.
