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 a report from the supplier of a manufacturing quality escape in which some sensing elements were manufactured with insufficient salt fill. This could result in an inability to detect hot bleed air leaks. This proposed AD would require, depending on airplane serial number, reviewing the airplane maintenance records for affected bleed leak detection system sensing elements, testing the sensing elements, replacing those that fail, and witness marking those that pass, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by reference. This proposed AD would also prohibit the installation of affected parts under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.

SUMMARY: 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 a report from the
supplier of a manufacturing quality escape in which some sensing
elements were manufactured with insufficient salt fill. This could
result in an inability to detect hot bleed air leaks. This proposed AD
would require, depending on airplane serial number, reviewing the
airplane maintenance records for affected bleed leak detection system
sensing elements, testing the sensing elements, replacing those that
fail, and witness marking those that pass, as specified in a Transport
Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by
reference. This proposed AD would also prohibit the installation of
affected parts under certain conditions. The FAA is

Background
TCCA, which is the aviation authority for Canada, has issued TCCA
AD CF-2022-13, dated March 28, 2022 (TCCA AD CF-2022-13) (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.
The MCAI states that Airbus Canada Limited Partnership received
disclosure letters from the supplier that reported a manufacturing
quality escape in which some of the overheat detection sensing elements
were manufactured with insufficient salt fill. These sensing elements
are used by the bleed air leak detection system for temperature
detection in the event of a hot bleed air leak. Insufficient salt fill
can result in an inability to detect hot bleed air leaks, which can
cause damage to surrounding structures and systems that could prevent
continued safe flight and landing.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-1483.
Related Service Information Under 1 CFR Part 51
TCCA AD CF-2022-13 specifies procedures for, depending on airplane
serial number, reviewing the airplane maintenance records for affected
bleed leak detection system sensing elements, testing the sensing
elements, replacing those that fail, and witness marking those that
pass. TCCA AD CF-2022-13 also prohibits the installation of any
affected parts unless it is a serviceable part.
Kidde Aerospace & Defense Service Bulletin CFD-26-1, Revision 6,
dated February 28, 2022, specifies affected continuous fire detector
(CFD) part numbers and testing procedures.
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, 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 TCCA AD CF-2022-13 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
[[Page 72418]]
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-2022-13 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
TCCA AD CF-2022-13 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-2022-13
for compliance will be available at <a href="http://regulations.gov">regulations.gov</a> under Docket No.
FAA-2022-1483 after the FAA final rule is published.
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
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 125 work[dash]hours x $85 per 0 Up to $10,625................ Up to $552,500.
hour = $10,625 (for Group A, 52
airplanes).
Up to 1 work[dash]hours x $85 per 0 Up to $85.................... Up to $1,445.
hour = $85 (for Group B, 17
airplanes).
----------------------------------------------------------------------------------------------------------------
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 actions:
Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
Up to 58 work-hours x $85 per hour = Up to $101,045.................... Up to $105,975.
$4,930 (for Group A airplanes).
Up to 183 work-hours x $85 per hour = Up to $101,045.................... Up to $116,600.
$15,555 (for Group B airplanes).
----------------------------------------------------------------------------------------------------------------
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
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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:
Airbus Canada Limited Partnership (Type Certificate Previously Held
by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.):
Docket No. FAA-2022-1483; Project Identifier MCAI-2022-00435-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by January 9, 2023.
(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
