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
<a href="http://regulations.gov">regulations.gov</a>, 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

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 has received a report that certain No. 1 flight compartment
windows may not meet type design requirements for withstanding a bird
impact due to the elimination of a witness test specimen and process
changes that affect main bondline strength. A number of these windows
were delivered to operators of Boeing Model 787-8, 787-9, and 787-10
airplanes.
In the event of a high-energy bird impact, these windows may spall.
This condition, if not addressed, could result in injuries to crew that
may affect continued safe flight and landing.
FAA's Determination
The FAA is issuing this NPRM after determining that the unsafe
condition described previously is likely to exist or develop on other
products of the same type design.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Alert Requirements Bulletin B787-81205-
SB560010-00 RB, Issue 001, dated December 13, 2023. This service
information specifies procedures for determining whether a left or
right No. 1 flight compartment window with certain part numbers and
serial numbers is installed and for replacing any window that has an
affected part number and serial number.
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.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described, except for any
differences identified as exceptions in the regulatory text of this
proposed AD. This proposed AD would also prohibit the installation of
affected parts. For information on the procedures, see this service
information at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2024-1303.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 152 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost airplane operators
----------------------------------------------------------------------------------------------------------------
Inspect right and left No. 1 windows.. 0.25 work-hour x $85 per $0 $21.25 $3,230
hour = $21.25.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any replacements that
would be required based on the results of the proposed inspection. The
agency has no way of determining the number of airplanes that might
need these replacements or how many replacements each airplane may
require:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per airplane
----------------------------------------------------------------------------------------------------------------
Replace No. 1 window.................... 16 work-hours x $85 per $104,060 $105,420 per window.
hour = $1,360.
----------------------------------------------------------------------------------------------------------------

Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.
Regulatory Findings
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
The Boeing Company: Docket No. FAA-2024-1303; Project Identifier AD-
2023-01252-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by July 5, 2024.
