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 indicating that at various lavatory and galley locations within the airplane, incorrect terminal lugs were installed which are not compatible with the associated wire gauge. This AD requires removing and replacing existing lug terminals at various lavatory and galley locations, 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 May 6, 2024 (89 FR 37144).
The NPRM was prompted by AD CF-2023-67, dated October 4, 2023, issued
by Transport Canada, which is the aviation authority for Canada
(Transport Canada AD CF 2023-67) (also referred to as the MCAI). The
MCAI states that at lavatory and galley locations within the airplane,
incorrect terminal lugs have been installed which are not compatible
with the associated wire gauge.
In the NPRM, the FAA proposed to require removing and replacing
existing lug terminals at various lavatory and galley locations, as
specified in Transport Canada AD CF-2023-67. The FAA is issuing this AD
to address incorrect terminal lugs that may become loose causing a loss
of electromagnetic interference protection, which could result in false
alarms of the lavatory smoke detectors, false alarms of low crew oxygen
pressure, loss of automatic control of automatic cabin temperature
control, and loss of lavatory flush. The unsafe condition, if not
corrected, could result in an increase in crew workload, including
diversions and descent to below 10,000 feet or the lowest safe
altitude.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-1289.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from Air Line Pilots Association,
International (ALPA), who supported the NPRM without change.
The FAA received an additional comment from an individual, who
requested to be informed as to how the FAA will continue coordination
between the FAA and Transport Canada to ensure the effectiveness of the
AD, and to address any emerging issues related to the replacement of
terminal lugs.
The FAA continuously evaluates operator and manufacturer reports
and other data to promote safe type certification and production. Since
this commenter did not ask for a change to the final rule, no change
has been made to this AD in response to this request.
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.
Material Incorporated by Reference Under 1 CFR Part 51
Transport Canada AD CF-2023-67 specifies procedures for removing
existing terminal lugs and installing new terminal lugs at lavatories
A, C1, C2, C3, D2, D4, and E, and galleys G2A, G2G, and G4, including
replacing the ground wires for new terminal lugs if the ground wire
length is not sufficient; and installing the service bulletin
incorporation placards.
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 66 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 81 work-hours x $85 per hour = (*) Up to $6,885..................... Up to $454,410.
Up to $6,885.
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost estimates for the parts specified in this
AD.
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all the costs of this
AD may be covered under warranty, thereby reducing the cost impact on
affected operators.
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 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.
[[Page 73264]]
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.
