The AD applies to certain The Boeing Company Model 787-9 and 787-10 airplanes. As published, a reference to the Alternative Methods of Compliance (AMOCs) paragraph in the regulatory text is incorrect. This document corrects that error. In all other respects, the original document remains the same. ## The airworthiness directive 1. The authority citation for part 39 continues to read as follows: 2. The FAA amends § 39.13 by adding the following new airworthiness directive: 2025-06-13 The Boeing Company: Amendment 39-23001; Docket No. FAA-2024-1301; Project Identifier AD-2024-00035-T. ### (a) Effective Date This airworthiness directive (AD) is effective July 2, 2025. ### (b) Affected ADs None. ### (c) Applicability This AD applies to The Boeing Company Model 787-9 and 787-10 airplanes, certificated in any category, as identified in Boeing Alert Requirements Bulletin B787-81205-SB530084-00 RB, Issue 002, dated September 5, 2024. ### (d) Subject Air Transport Association (ATA) of America Code 53, Fuselage. ### (e) Unsafe Condition This AD was prompted by reports that some floor beam side-of-body fittings have been manufactured with an incorrect material type between station 1233 and station 1593. The FAA is issuing this AD to address the floor beam side-of-body fittings that do not meet type design and prevent failure of the fittings. The unsafe condition, if not addressed, could result in the inability of the surrounding principal structure elements to sustain limit loads and damage to critical systems under the floor; these conditions could cause loss of control of the airplane. Additionally, in the event of an emergency landing or full certified rapid decompression, failure of multiple adjacent fittings could result in the inability of the passenger floor grid to maintain the loads and could result in serious injury or impeded egress for passengers. ### (f) Compliance Comply with this AD within the compliance times specified, unless already done. ### (g) Required Actions Except as specified in paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin B787-81205-SB530084-00 RB, Issue 002, dated September 5, 2024, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin B787-81205-SB530084-00 RB, Issue 002, dated September 5, 2024. Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin B787-81205-SB530084-00, Issue 002, dated September 5, 2024, which is referred to in Boeing Alert Requirements Bulletin B787-81205-SB530084-00 RB, Issue 002, dated September 5, 2024. ### (h) Exceptions to Service Information Specifications (1) Where the “Boeing Recommended Compliance Time” column in the tables under the “Compliance” paragraph of Boeing Alert Requirements Bulletin B787-81205-SB530084-00 RB, Issue 002, dated September 5, 2024, refers to “the Issue 001 date of Requirements Bulletin B787-81205-SB530084-00 RB,” this AD requires using the effective date of this AD. (2) Where Boeing Alert Requirements Bulletin B787-81205-SB530084-00 RB, Issue 002, dated September 5, 2024, specifies contacting Boeing for repair instructions, this AD requires doing the repair before further flight using a method approved in accordance with the procedures in paragraph (j) of this AD. (3) Where footnote [2] in Tasks 3, 5, 8, 10, 13, 15, 18, 20, 23, 25, 28, 31, 33, 36, 38, 41, 43, 46, 48, 51, 53, and 56 of Boeing Alert Requirements Bulletin B787-81205-SB530084-00 RB, Issue 002, dated September 5, 2024, uses the phrase “Chamfer edges of fastener holes common to the SOB fitting,” for this AD, replace that phrase with “Chamfer edges of fastener holes common to the fuselage frame, once installed.” ### (i) Credit for Previous Actions This paragraph provides credit for the actions specified in paragraph (g) of this AD, if those actions were performed before the effective date of this AD using Boeing Alert Requirements Bulletin B787-81205-SB530084-00 RB, Issue 001, dated December 8, 2023. ### (j) Alternative Methods of Compliance (AMOCs) (1) The Manager, AIR-520, Continued Operational Safety Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

For some repairs, AD 2025-06-13 requires using a method approved in accordance with the FAA's AMOC procedures. ### Need for Correction As published, a reference to the AMOC paragraph in the regulatory text of AD 2025-06-13 is incorrect. Paragraph (h)(2) of AD 2025-06-13 inadvertently referred to paragraph (i) of the AD (“Credit for Previous Actions”) instead of paragraph (j) of the AD (“Alternative Methods of Compliance (AMOCs)”). ### Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Boeing Alert Requirements Bulletin B787-81205-SB530084-00 RB, Issue 002, dated September 5, 2024. This material specifies performing an X-ray fluorescence spectrometer inspection or a high frequency eddy current inspection of the floor beam side-of-body fittings between station 1233 and station 1593 to determine whether the fitting was manufactured with type design grade 5 Ti-6AI-4V material. Alternatively, operators may replace all floor beam side-of-body fittings between station 1233 and station 1593 with fittings made of the correct material without performing an inspection. For any floor beam side-of-body fitting that needs replacement, this material specifies inspecting the fuselage frame and fuselage fastener holes for damage, repairing any damage, and installing a floor beam side-of-body fitting made of the correct material. This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. ### Correction of Publication This document corrects an error and correctly adds the AD as an amendment to 14 CFR 39.13. Although no other part of the preamble or regulatory information has been corrected, the FAA is publishing the entire rule in the Federal Register. The effective date of this AD remains July 2, 2025. Since this action only corrects a reference to the AMOC paragraph, it has no adverse economic impact and imposes no additional burden on any person. Therefore, the FAA has determined that notice and public comment procedures are unnecessary. ### Adoption of the Amendment Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: ## Affected data sheets (1) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS T00021SE](https://openairdocs.org/tcds/T00021SE): The Boeing Company; names 2 of 3 models: 787-10, 787-9 ## Registered aircraft it may apply to (OpenAirDocs) Matched by airframe and engine model; the AD's applicability may narrow it by serial number, part number or equipment. - Aircraft: 139 (139 by airframe model, 0 by engine model) - Makers: Boeing 139 Models with the most aircraft: - [Boeing 787-9](https://openairdocs.org/model/boeing-787-9): 118 aircraft (airframe model) - [Boeing 787-10](https://openairdocs.org/model/boeing-787-10): 21 aircraft (airframe model) All 2 models: https://openairdocs.org/ad/2025-06-13/models.md Every aircraft: https://openairdocs.org/ad/2025-06-13/aircraft.md ## Related documents - [Proposed rule FAA-2024-1301](https://openairdocs.org/proposed/FAA-2024-1301): Notice of proposed rulemaking (NPRM), published May 17, 2024 Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
