Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Model BD-500-1A10 and BD-500-1A11 airplanes. This AD was prompted by the potential for the flexible hose assembly of the fuel motive flow (MF), installed between the pylon and wing, to be installed twisted in the shroud, which can restrict the flow of fuel for the MF and cause fuel imbalance and damage to the shroud assembly. This AD requires inspecting for damage of the left and right MF fuel line assemblies (including the flexible-hose and shroud assemblies), and replacing damaged parts, 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.

SUPPLEMENTARY INFORMATION:
Background
TCCA, which is the aviation authority for Canada, has issued TCCA
AD CF-2021-09, dated March 11, 2021 (TCCA AD CF-2021-09) (also referred
to as the Mandatory Continuing Airworthiness Information, or the MCAI),
to correct an unsafe condition for certain Airbus Canada Limited
Partnership Model BD-500-1A10 and BD-500-1A11 airplanes.
This AD was prompted by the determination that a new configuration
of the pylon-to-wing area MF flexible fuel line assembly was introduced
without revision or modification to the installation procedure,
potentially resulting in a twisted MF flexible fuel line in the shroud.
This can restrict the flow of fuel of the MF, which can cause fuel
imbalance and possible damage including abrasion to the shroud
assembly. The FAA is issuing this AD to address this condition, which
could result in the consequent abrasion of the fuel line and a possible
fuel leak; as a result, the electrical harness connectors in the wing
area could be a potential ignition source and pose a risk of fire. See
the MCAI for additional background information.
Related Service Information Under 1 CFR Part 51
TCCA AD CF-2021-09 describes procedures for a general visual
inspection for damage (including permanent deformities) of the left and
right MF fuel line assemblies (including the flexible-hose assembly and
shroud assembly), and replacement of affected MF fuel line assemblies
(including cleaning of the ends of the flexible-hose assembly,
injecting grease at both ends of the flexible-hose assembly, and
torqueing the aft end of the flexible-hose assembly). 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
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 the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
referenced above. The FAA is issuing this AD because the FAA evaluated
all pertinent information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.
Requirements of This AD
This AD requires accomplishing the actions specified in TCCA AD CF-
2021-09 described previously, as incorporated by reference, except for
any differences identified as exceptions in the regulatory text of this
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,
TCCA AD CF-2021-09 is incorporated by reference in this AD. This AD
requires compliance with TCCA AD CF-2021-09 in its entirety through
that incorporation, except for any differences identified as exceptions
in the regulatory text of this AD. Service information required by TCCA
AD CF-2021-09 for compliance will be available at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2021-
0669 after this AD is published.
FAA's Justification and Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies waiving notice and comment prior to adoption of this rule
because a twisted MF flexible fuel line in the shroud can restrict the
flow of fuel of the MF and cause fuel imbalance and possible damage
including abrasion to the shroud assembly and fuel line, resulting in a
fuel leak; as a result, the electrical harness connectors in the wing
area are a potential ignition source and pose a risk of fire. In
addition, the compliance time for the required action is shorter than
the time necessary for the public to comment and for publication of the
final rule. Therefore, the FAA finds good cause that notice and
opportunity for prior public comment are impracticable. In addition,
for the reasons stated above, the FAA finds that good cause exists for
making this amendment effective in less than 30 days.
Comments Invited
The FAA invites you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
ADDRESSES. Include ``Docket No. FAA-
[[Page 44602]]
2021-0669; Project Identifier MCAI-2021-00314-T'' at the beginning of
your comments. The most helpful comments reference a specific portion
of the final rule, 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 final rule 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="https://www.regulations.gov">https://www.regulations.gov</a>, including any personal information you
provide. The agency will also post a report summarizing each
substantive verbal contact received about this final rule.
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 AD 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 AD, 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 AD. Submissions containing CBI should be sent to Jiwan
Karunatilake, Aerospace Engineer, Airframe and Propulsion Section, FAA,
New York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY
11590; telephone 516-228-7300; fax 516-794-5531; email <a href="/cdn-cgi/l/email-protection#3d04105c4b4e1053445c5e52105e524e7d5b5c5c135a524b"><span class="__cf_email__" data-cfemail="e9d0c4889f9ac48790888a86c48a869aa98f8888c78e869f">[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.
Regulatory Flexibility Act (RFA)
The requirements of the RFA do not apply when an agency finds good
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and
comment. Because the FAA has determined that it has good cause to adopt
this rule without notice and comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 5 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
----------------------------------------------------------------------------------------------------------------
7 work-hours x $85 per hour = $595........................... $0 $595 $2,975
----------------------------------------------------------------------------------------------------------------
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 this on-condition actions:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
0.5 work-hour x $85 per hour = $42.50. $20,260 $20,302.50
------------------------------------------------------------------------
According to the manufacturer, some or all of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected operators. The FAA does not control warranty coverage for
affected operators. As a result, the FAA has included all known costs
in the cost estimate.
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 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, and
(2) Will not affect intrastate aviation in Alaska.

2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2021-17-07 Airbus Canada Limited Partnership (Type Certificate
Previously Held by C Series Aircraft Limited Partnership (CSALP);
Bombardier, Inc.): Amendment 39-21690; Docket No. FAA-2021-0669;
Project Identifier MCAI-2021-00314-T.
(a) Effective Date
This airworthiness directive (AD) becomes effective August 30,
2021.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Airbus Canada Limited Partnership (type
certificate previously held by C Series Aircraft Limited Partnership
(CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11
airplanes, certificated in any category, as identified in Transport
Canada Civil Aviation (TCCA) AD CF-2021-09, dated March 11, 2021
(TCCA AD CF-2021-09).
(d) Subject
Air Transport Association (ATA) of America Code 28, Aircraft
fuel system.
(e) Reason
This AD was prompted by the potential for the flexible hose
assembly of the fuel motive flow (MF), installed between the pylon
and wing, to be installed twisted in the shroud, which can restrict
the flow of fuel for the MF and cause fuel imbalance and possible
damage, including abrasion, to the shroud assembly. The FAA is
issuing this AD to address this condition, which could result in
abrasion of the fuel line and a possible fuel leak; as a result, the
electrical harness connectors in the wing area could be a potential
ignition source and pose a risk of fire.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraph (h) of this AD: Comply with all
required actions and compliance times specified in, and in
accordance with, TCCA AD CF-2021-09.
(h) Exception to TCCA AD CF-2021-09
(1) Where TCCA AD CF-2021-09 refers to its effective date, this
AD requires using the effective date of this AD.
(2) Where TCCA AD CF-2021-09 specifies replacing MF fuel line
assemblies, this AD requires that replacement before further flight
after any damage (including any permanent deformity) is detected.
(i) No Return of Parts
Although the service information referenced in TCCA AD CF-2021-
09 specifies to return certain parts to the manufacturer, this AD
does not include that requirement.
