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 reports that the engine feed pressure switches were installed with no secondary locking mechanism and can become loose and cause a fuel leak. This AD requires initial and repetitive inspections at the engine feed pressure switch locations and installation of a flange adaptor with lockwire to terminate the repetitive inspections, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

-----------------------------------------------------------------------
SUMMARY: 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 reports that the engine feed
pressure switches were installed with no secondary locking mechanism
and can become loose and cause a fuel leak. This AD requires initial
and repetitive inspections at the engine feed pressure switch locations
and installation of a flange adaptor with lockwire to terminate the
repetitive inspections, as specified in a Transport Canada Civil
Aviation (TCCA) AD, which is incorporated by reference. The FAA is
issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective December 14, 2022.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of December 14,
2022.

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 July 29, 2022 (87 FR 45712).
The NPRM was prompted by AD CF-2021-50, dated December 21, 2021, issued
by TCCA, which is the aviation authority for Canada (referred to after
this as the MCAI). The MCAI states that certain fuel system pressure
switches have been installed on the left-hand and right-hand wings
without a secondary locking feature (lockwire). This condition may
allow the fuel pressure switches to become loose and allow fuel to leak
in the affected areas, creating a fire hazard.
In the NPRM, the FAA proposed to require initial and repetitive
inspections at the engine feed pressure switch locations and
installation of a flange adaptor with lockwire to terminate the
repetitive inspections, as specified in TCCA AD CF-2021-50. The FAA is
issuing this AD to address the unsafe condition on these products.
[[Page 67544]]
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-0982.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
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 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
TCCA AD CF-2021-50 specifies procedures for repetitive general
visual inspections of the torque identification stripes, torquing of
the fuel pressure switches, and installation of lockwire at the two
alternating current (AC) boost pump cartridges; repetitive general
visual inspections of the torque identification stripes and torquing of
the fuel pressure switches at the two engine feed pressure switches;
and installation of a new flange adaptor and lockwire, which terminates
the repetitive inspections. 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 60 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Up to 27 work-hours x $85 per hour = $811 Up to $2,295........................ $137,700
$2,295.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need these on-condition action:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
14 work-hours x $85 per hour = $1,190. $0 $1,190
------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of 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.
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.

The Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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:
2022-21-03 Airbus Canada Limited Partnership (Type Certificate
Previously Held by C Series Aircraft Limited Partnership (CSALP);
Bombardier, Inc.): Amendment 39-22202; Docket No. FAA-2022-0982;
Project Identifier MCAI-2021-00787-T.
(a) Effective Date
This airworthiness directive (AD) is effective December 14,
2022.
[[Page 67545]]
(b) Affected ADs
None.
(c) Applicability
This AD applies to Airbus Canada Limited Partnership Model BD-
500-1A10 and BD-500-1A11 airplanes, certificated in any category, as
identified in Transport Canada Civil Aviation (TCCA) AD CF-2021-50,
dated December 21, 2021 (TCCA AD CF-2021-50).
