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

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Airbus Canada
Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. The
NPRM published in the Federal Register on November 6, 2023 (88 FR
76144). The NPRM was prompted by AD CF-2023-27, dated May 4, 2023,
issued by Transport Canada, which is the aviation authority for Canada
(Transport Canada AD CF-2023-27) (also referred to as the MCAI). 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.
In the NPRM, the FAA proposed to require rerouting the power
harness, as specified in Transport Canada AD CF-2023-27. The FAA is
issuing 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.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from the Air Line Pilots Association,
International (ALPA) who supported the NPRM without change.
The FAA received an additional comment from Delta Air Lines
(Delta). The following presents the comment received on the NPRM and
the FAA's response to the comment.
Request To Confirm Intent To Allow Usage of Later Service Bulletin
Revisions
Delta requested confirmation that a later service bulletin revision
could be used to comply with paragraph (g) of the proposed AD. Delta
noted that, per Transport Canada AD CF-2023-27 Corrective Actions, a
later revision of the service bulletin can be used to comply with the
required corrective actions and added that Airbus A220 Service Bulletin
BD500-352004 Issue 02, dated June 6, 2023, was recently issued.
The FAA confirms that it intends to allow the use of applicable
later-approved service information to comply with the requirements of
this AD. This AD refers to Transport Canada AD CF-2023-27 as the
appropriate source of service information for accomplishing the
required actions. Transport Canada AD CF-2023-27 includes a Corrective
Actions section, which accepts the use of later approved revisions of
the referenced service information for compliance. Therefore,
applicable later approved service information revisions are acceptable.
The FAA has not changed this AD in this regard.
Conclusion
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 reviewed the relevant data, considered the
comments received, and determined that air safety requires adopting
this AD as proposed. Accordingly, the FAA is issuing this AD to address
the unsafe condition on this product. Except for minor editorial
changes, this AD is adopted as proposed in the NPRM. None of the
changes will increase the economic burden on any operator.
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 the ADDRESSES section.
Costs of Compliance
The FAA estimates that this AD affects 29 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost 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
This AD will not have federalism implications under Executive Order
13132. This AD will not have a
[[Page 19507]]
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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
