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. That AD applies to all The Boeing 
Company Model 757 airplanes. As published, the AD number referenced 
throughout the final rule is incorrect. This document corrects that 
error. In all other respects, the original document remains the same.

DATES: This correction is effective August 22, 2024. The effective date 
of AD 2024-12-09 remains August 22, 2024.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 22, 
2024 (89 FR 58257, July 18, 2024).

SUPPLEMENTARY INFORMATION:

Background

    AD 2024-12-09, Amendment 39-22773 (89 FR 58257, July 18, 2024), 
requires an inspection or records check of the wing upper skin at the 
drag fitting attachment holes for any existing repair; repetitive 
inspections for loose fasteners, skin cracking, and shim migration at 
the upper link drag fittings, and for cracking in the diagonal brace 
and diagonal brace fittings; repetitive inspections for cracking of the 
fastener holes and loose bolt holes; and applicable on-condition 
actions for all The Boeing Company Model 757 airplanes.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin 757-57A0073 RB, 
Revision 3, dated May 5, 2023. This material specifies procedures for a 
general visual inspection or records check of the wing upper skin at 
the drag fitting attachment holes for any existing repair; repetitive 
general visual and detailed inspections for loose fasteners, skin 
cracking, and shim migration at the upper link drag fittings, and for 
cracking in the diagonal brace and diagonal brace fittings; repetitive 
open-hole high frequency eddy current (HFEC) inspections for cracking 
of the fastener holes and loose bolt holes; and applicable on-condition 
actions. On-condition actions include performing an ultrasonic 
inspection for cracks at any repaired upper wing skin location; 
installing the upper link and upper link pins; replacing drag fittings; 
installing bolts, washers, and nuts; performing a torque check of 
fasteners on the affected shims; trimming affected shims and applying 
chemical conversion coating on the shims, fillet seal, and drag 
fittings; and repairing cracks, migrated shims, mistorqued bolts, and 
loose fasteners. 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 ADDRESSES.

Need for Correction

    As published, the AD number referenced throughout the final rule is 
incorrect. The final rule incorrectly references ``AD 2023-12-09.'' The 
correct AD number is ``AD 2024-12-09.''

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 August 22, 2024.
    Since this action only corrects an incorrect AD number, 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 FAA 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:
0
a. Removing Airworthiness Directive (AD) 2022-08-12, Amendment 39-22015 
(87 FR 26964, May 6, 2022); and
0
b. Adding the following new AD:

2024-12-09 The Boeing Company: Amendment 39-22773; Docket No. FAA-
2023-2395; Project Identifier AD-2023-00767-T.

(a) Effective Date

    This airworthiness directive (AD) is effective August 22, 2024.

(b) Affected ADs

    This AD replaces AD 2022-08-12, Amendment 39-22015 (87 FR 26964, 
May 6, 2022) (AD 2022-08-12).

(c) Applicability

    This AD applies to all The Boeing Company Model 757-200, PF, -
200CB, and -300 series airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 57, Wings.

(e) Unsafe Condition

    This AD was prompted by reports of bolt rotation in the engine 
drag fitting joint and fastener heads and cracks found in the skin 
of the fastener holes, a determination that certain drag fittings 
may be made of alternate materials, which could result in reduced 
structural integrity of the engine strut, and a determination that 
additional inspections and revised compliance times are needed. The 
FAA is issuing this AD to address cracking in the wing upper skin 
and forward drag fittings, which could lead to a compromised upper 
link and reduced structural integrity of the engine strut, and 
possible separation of a strut and engine from the airplane during 
flight.

(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
