Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: The FAA is correcting an airworthiness directive (AD) that was 
published in the Federal Register. 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.

DATES: This correction is effective July 2, 2025. The effective date of 
AD 2025-06-13 remains July 2, 2025.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 2, 2025 
(90 FR 22442, May 28, 2025).

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov by 
searching for and locating Docket No. FAA-2024-1301; or in person at 
Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The AD docket contains this final rule, any 
comments received, and other information. The street address for Docket 
Operations is listed above.

SUPPLEMENTARY INFORMATION:

Background

    AD 2025-06-13, Amendment 39-23001 (90 FR 22442, May 28, 2025) (AD 
2025-06-13), requires replacing the incorrectly manufactured floor beam 
side-of-body fittings, inspecting the fuselage frame and fastener holes 
for damage, and repairing any damage for certain The Boeing Company 
Model 787-9 and 787-10 airplanes. 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

[[Page 24063]]

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.

reference, Safety.

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:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Corrected]

0
2. The FAA amends Sec.  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)

FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14

(k)(1) of this AD. Information may be emailed to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the responsible Flight Standards Office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by The Boeing Company Organization Designation 
Authorization (ODA) that has been authorized by the Manager, AIR-
520, Continued Operational Safety Branch, FAA, to make those 
findings. To be approved, the repair method, modification deviation, 
or alteration deviation must meet the certification basis of
