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

Background
The TCCA, which is the aviation authority for Canada, has issued
TCCA AD CF-2021-50, dated December 21, 2021 (TCCA AD CF-2021-50) (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.
This proposed AD was prompted by reports that certain fuel system
pressure switches have been installed without a secondary locking
feature (lockwire). The fuel pressure switches are installed on the
alternating current (AC) boost pump cartridge located in the wing dry
bay (outboard of rib 6) and near the engine feed pressure switch, on
the rear spar (between ribs 8 and 9). Both installations exist on the
left-hand and right-hand wings for a total of four affected locations
on the airplane. The FAA is proposing this AD to address the absence of
a secondary locking feature (lockwire) on the fuel pressure switches,
which may allow them to become loose and allow fuel to leak in the
affected areas, creating a fire hazard. See the MCAI for additional
background information.
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 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.
FAA's Determination
These products have been approved by the aviation authority of
another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with the 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 these same type designs.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in TCCA AD CF-2021-50 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 TCCA AD CF-2021-50 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
TCCA AD CF-2021-50 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 TCCA AD CF-2021-50
for compliance will be available at <a href="http://www.regulations.gov">www.regulations.gov</a> by searching
for and locating Docket No. FAA-2022-0982 after the FAA final rule is
published.
Costs of Compliance
The FAA estimates that this proposed AD would affect 60 airplanes
of U.S. registry. The FAA estimates the following costs to comply with
this proposed 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 = $2,295. $811 Up to $2,295...................... $137,700
----------------------------------------------------------------------------------------------------------------
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 proposed AD may be covered under warranty, thereby reducing the
cost impact on affected operators.
[[Page 45714]]
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
