2024-25-08: Landing Gear

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2024-25-08 The Boeing Company: Amendment 39-22910; Docket No. FAA-2024-1689; Project Identifier AD-2024-00109-T. (a) Effective Date This airworthiness directive (AD) is effective February 12, 2025. (b) Affected ADs None. (c) Applicability (1) This AD applies to all The Boeing Company Model 767-200, -300, and -300F series airplanes, certificated in any category. (2) Installation of Supplemental Type Certificate (STC) ST01920SE does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01920SE 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. (d) Subject Air Transport Association (ATA) of America Code 32, Landing Gear. (e) Unsafe Condition This AD was prompted by a report of a main landing gear (MLG) collapse event following maintenance where a grinder was operating outside of its input parameters, resulting in possible heat damage to the outer cylinder of the MLG. The FAA is issuing this AD to address any heat damage to the outer cylinder of the landing gear. The unsafe condition, if not addressed, could result in the inability of a principal structural element to sustain limit load, gear collapse resulting in loss of control of the airplane, and potential for off-runway excursion. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) 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 767-32A0253 RB, dated February 6, 2024, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 767-32A0253 RB, dated February 6, 2024.

(h) Exceptions to Service Information Specifications Where the Boeing Recommended Compliance Time column of the table in the "Compliance" paragraph of Boeing Alert Requirements Bulletin 767-32A0253 RB, dated February 6, 2024, uses the phrase "the Original Issue date of Requirements Bulletin 767-32A0253 RB," this AD requires using the effective date of this AD.
