Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by a report of possible chafing of a power harness at fuselage frame (FR) 65. This proposed AD would require rerouting the power harness, as specified in a Transport Canada AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

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 ADDRESSES. Include ``Docket No. FAA-2023-2146; Project Identifier
MCAI-2023-00646-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
<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

Suite 410, Westbury, NY 11590; telephone: 516-228-7301; email: <a href="/cdn-cgi/l/email-protection#c2fbefa3b4b1efacbba3a1adefa1adb182a4a3a3eca5adb4"><span class="__cf_email__" data-cfemail="427b6f2334316f2c3b23212d6f212d31022423236c252d34">[email protected]</span></a>. Any commentary that the FAA receives which is not
specifically designated as CBI will be placed in the public docket for
this rulemaking.
Background
Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD CF-2023-27, dated May 4, 2023 (Transport
Canada AD CF-2023-27) (also referred to as the MCAI), to correct an
unsafe condition for certain Airbus Canada Limited Partnership Model
BD-500-1A10 and BD-500-1A11 airplanes. The MCAI states that during
production, a possibility of chafing between a power harness and the
left side window shade at fuselage FR 65 was detected. Damage to the
power harness can result in an emergency equipment failure, including
the partial loss of the public address system and the inability to
deploy half the passenger oxygen masks when required.
The FAA is proposing this AD to address the unsafe condition on
these products. You may examine the MCAI in the AD docket at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2023-2146.
Related Service Information Under 1 CFR Part 51
Transport Canada AD CF-2023-27 specifies procedures for rerouting
the power harness, which requires the modification of an insulation
blanket and the installation of a standoff and a clamp on the left side
stringer 11 between fuselage FR 65 and FR 67 to prevent damage to the
harness.
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 section.
FAA's Determination
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI
referenced above. The FAA is issuing this NPRM after determining that
the unsafe condition described previously is likely to exist or develop
in other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in Transport Canada AD CF-2023-27 described previously, except for any
differences identified as exceptions in the regulatory text of this
proposed AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA proposes to incorporate Transport Canada AD CF-2023-27 by reference
in the FAA final rule. This proposed AD would, therefore, require
compliance with Transport Canada AD CF-2023-27 in its entirety through
that incorporation, except for any differences identified as exceptions
in the regulatory text of this proposed AD. Service information
required by Transport Canada AD CF-2023-27 for compliance will be
available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2023-2146 after the
FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 29 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
[[Page 76146]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $85 per hour = $340.................. $10 $350 $10,150
----------------------------------------------------------------------------------------------------------------
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:
