Background
TCCA, which is the aviation authority for Canada, has issued TCCA
AD CF-2021-01, dated January 8, 2021 (TCCA AD CF-2021-01) (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 proposed AD was prompted by reports of loose powerplant FIREX
interconnection hoses, and in one instance a hose was found
disconnected. An investigation by the manufacturer determined that if
the instructions for connecting the FIREX hose are not followed
properly, hoses can become loose or disconnected. The FAA is proposing
this AD to address the possibility that fire extinguishing agent may
not be effectively applied should a fire occur within a powerplant
assembly that has a partially or completely disconnected FIREX hose,
which could result in the inability to put out a fire in the engine.
See the MCAI for additional background information.
Related Service Information Under 1 CFR Part 51
TCCA AD CF-2021-01 describes procedures for replacing certain
existing FIREX hose assemblies on each powerplant with a newly designed
FIREX hose assembly with provisions for the installation of safety
cables at each end, in order to prevent the hose from becoming loose or
disconnected.
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 and Requirements of This Proposed AD
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 proposing this AD because the FAA
evaluated all the relevant information and determined the unsafe
condition described previously is likely to exist or develop in other
products of the same type design.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in TCCA AD CF-2021-01 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 initially worked with Airbus and the European Union
Aviation Safety Agency (EASA) to develop a process to use certain EASA
ADs as the primary source of information for compliance with
requirements for corresponding FAA ADs. The FAA has since coordinated
with other manufacturers and civil aviation authorities (CAAs) to use
this process. As a result, TCCA AD CF-2021-01 will be incorporated by
reference in the FAA final rule. This proposed AD would, therefore,
require compliance with TCCA AD CF-2021-01 in its entirety, through
that incorporation, except for any differences identified as exceptions
in the regulatory text of this proposed AD. Service information
specified in TCCA AD CF-2021-01 that is required for compliance with
TCCA AD CF-2021-01 will be available on the internet at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2021-
0696 after the FAA final rule is published.
[[Page 47426]]
Costs of Compliance
The FAA estimates that this proposed AD affects 36 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
----------------------------------------------------------------------------------------------------------------
5 work-hours x $85 per hour = $425........................... $13,012 $13,437 $483,732
----------------------------------------------------------------------------------------------------------------
According to the manufacturer, some or all of the costs of this
proposed 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 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
