Background
Transport Canada, which is the aviation authority for Canada, has
issued Transport Canada AD CF-2022-08, dated March 3, 2022 (Transport
Canada AD CF-2022-08) (also referred to as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for all 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. The MCAI states
there have been several in-service findings of mechanical wear damage
on the engine fuel feed system tubes and fuel tube connections on
airplanes that are ``post-SB BD500-282004'' or that have the production
equivalent. Transport Canada AD CF-2019-19R1, dated November 1, 2019
(Transport Canada AD CF-2019-19R1), among other actions, mandates
modifying the fuel feed line installations in the fuel collector tanks
using ACLP Service Bulletin BD500-282004, Issue 1, dated August 30,
2019. Transport Canada AD CF-2019-19R1 corresponds to FAA AD 2022-02-
07, Amendment 39-21904 (87 FR 7027, February 8, 2022).
This proposed AD would require repetitive inspections of the fuel
feed system for damage and replacement if necessary, as specified in
Transport Canada AD CF-2022-08, which is proposed for incorporation by
reference. The FAA is proposing this AD to address mechanical wear
damage on the engine fuel feed system tubes and fuel tube connections.
The unsafe condition, if not addressed, could result in failure of the
affected fuel tubes and subsequent failure of the gravity transfer
system, which could lead to a fuel imbalance resulting in a reduction
in aircraft functional capabilities and increased crew workload. See
the MCAI for additional background information.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-1566.
Related Service Information Under 1 CFR Part 51
Transport Canada AD CF-2022-08 specifies procedures for repetitive
general visual inspections for mechanical wear damage (damage includes
cracks, scores, scratches, nicks, and gouges) of the fuel feed system
(the fuel feed tubes, related attaching hardware, and the area where
the saddle clamp was installed), and rectification, such as replacement
if any discrepancy is found after measuring any damage found during any
inspection.
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 ADDRESSES.
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, it
has notified the FAA of the unsafe condition described in the MCAI
described 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 the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in Transport Canada AD CF-2022-08 described previously, as incorporated
by reference, except for any group 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 Transport Canada AD CF-2022-08 by reference
in the FAA final rule. This proposed AD would, therefore, require
compliance with Transport Canada AD CF-2022-08 in its entirety through
that incorporation,
[[Page 74529]]
except for any differences identified as exceptions in the regulatory
text of this proposed AD. Service information required by Transport
Canada AD CF-2022-08 for compliance will be available at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2022-1566 after the FAA final rule
is published.
Interim Action
The FAA considers that this proposed AD would be an interim action.
This AD is considered interim action and further AD action may follow.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 69 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
74 work-hours x $85 per hour = $6,290........................ $0 $6,290 $434,010
----------------------------------------------------------------------------------------------------------------
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
7 work-hours x $85 per hour = $57,284 Up to $57,879.
$595.
------------------------------------------------------------------------
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.
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
