the docket number referenced throughout the NPRM is incorrect. This 
document corrects that error. In all other respects, the original 
document remains the same; however, for clarity, the FAA is publishing 
the entire proposed rule in the Federal Register.

June 20, 2024) remains August 5, 2024.

SUPPLEMENTARY INFORMATION:

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2024-1689; 
Project Identifier AD-2024-00109-T'' at the beginning of your comments. 
The most helpful comments reference a specific portion of the proposal, 
explain the reason for any recommended change, and include supporting 
data. The FAA will consider all comments received by the closing date 
and may amend this proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to 
Stefanie Roesli, Aviation Safety Engineer, FAA, 2200 South 216th St., 
Des Moines, WA 98198; phone: 206-231-3964; email: 
[email protected]. Any commentary that the FAA receives that is 
not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Background

    The FAA issued an NPRM (89 FR 51856, June 20, 2024) that would 
apply to all The Boeing Company Model 767-200, -300, and -300F series 
airplanes. The NPRM 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 NPRM proposed to require 
replacing any affected outer cylinders. The FAA is proposing 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 and potential for off runway excursion.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin 767-32A0253 RB, 
dated February 6, 2024. This service information specifies procedures 
for performing a check of maintenance records or performing an 
inspection of the left and right MLG outer cylinders for any affected 
part numbers and serial numbers and replacing affected cylinders. This 
service information 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 the Correction

    As published, the docket number referenced throughout the NPRM is 
incorrect. The NPRM incorrectly references ``Docket No. FAA-2024-
1688.'' The correct docket number is ``Docket No. FAA-2024-1689.''
    Although no other part of the preamble or regulatory information 
has been corrected, for clarity the FAA is publishing the entire 
proposed rule in the Federal Register.
    The comment due date of the NPRM remains August 5, 2024.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

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 and potential for off

unless already done.
