Background
The TCCA, which is the aviation
authority for Canada, has issued TCCA
AD CF–2021–46, dated December 8,
2021 (TCCA AD CF–2021–46) (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
a report of a TRAS deploy hose failure
upon the commanded deployment of a
thrust reverser. It was found that certain
TRAS deploy hoses were made with
incomplete installation of the wire
overbraid, which created a weak point
and subsequently led to failure of the
deploy hose. The FAA is proposing this
AD to address failure of a deploy hose,
which could lead to loss of thrust
reverser function and hydraulic
systems. Losing one or both thrust
reversers during landing on a
contaminated runway could lead to a
runway excursion. See the MCAI for
additional background information.
Related Service Information Under 1
CFR Part 51
TCCA AD CF–2021–46 specifies
procedures for removing each nonconforming TRAS deploy hose, and
replacing it with a conforming TRAS
deploy hose. This material is reasonably
available because the interested parties
PO 00000
Frm 00037
Fmt 4702
Sfmt 4702
have access to it through their normal
course of business or by the means
identified in the ADDRESSES section.
Explanation of Affected Thrust
Reversers
The service information referenced in
TCCA AD CF–2021–46 specifies a list of
affected thrust reversers (the nonconforming TRAS deploy hoses are
installed on the affected thrust
reversers). Airbus Canada has notified
the FAA that the list in Airbus Canada
Limited Partnership Service Bulletin
BD500–783002, Issue 001, dated
October 22, 2020, contains incorrect
part numbers for several serial numbers.
Later revisions of the service
information contain correct part and
serial numbers. In addition, Table 1 to
paragraph (h)(3) specifies the correct
part and serial numbers for the affected
thrust reversers.
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–2021–46 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–2021–46 by
reference in the FAA final rule. This
proposed AD would, therefore, require
compliance with TCCA AD CF–2021–46
in its entirety through that
incorporation, except for any differences
identified as exceptions in the
regulatory text of this proposed AD.

AD CF–2021–46 for compliance will be
available at regulations.gov by searching
for and locating Docket No. FAA–2022–
1236 after the FAA final rule is
published.
Costs of Compliance
The FAA estimates that this proposed
AD would affect 8 airplanes of U.S.
registry. The FAA estimates the
60351
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
3 work-hours × $85 per hour = $255 ..........................................................................................
* $0
$255
$2,040
* The FAA has received no definitive data on which to base the cost estimates for the parts specified in this proposed AD.
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
jspears on DSK121TN23PROD with PROPOSALS
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,

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
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 of a
thrust reverser actuation system (TRAS) deploy hose failure upon the
commanded deployment of a thrust reverser. This proposed AD would
require removing each non-conforming TRAS deploy hose, and replacing it
with a conforming TRAS deploy hose, 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.

commentary that the FAA receives which is not specifically designated
as CBI will be placed in the public docket for this rulemaking.
Background
The TCCA, which is the aviation authority for Canada, has issued
TCCA AD CF-2021-46, dated December 8, 2021 (TCCA AD CF-2021-46) (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 a report of a TRAS deploy hose
failure upon the commanded deployment of a thrust reverser. It was
found that certain TRAS deploy hoses were made with incomplete
installation of the wire overbraid, which created a weak point and
subsequently led to failure of the deploy hose. The FAA is proposing
this AD to address failure of a deploy hose, which could lead to loss
of thrust reverser function and hydraulic systems. Losing one or both
thrust reversers during landing on a contaminated runway could lead to
a runway excursion. See the MCAI for additional background information.
Related Service Information Under 1 CFR Part 51
TCCA AD CF-2021-46 specifies procedures for removing each non-
conforming TRAS deploy hose, and replacing it with a conforming TRAS
deploy hose. 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.
Explanation of Affected Thrust Reversers
The service information referenced in TCCA AD CF-2021-46 specifies
a list of affected thrust reversers (the non-conforming TRAS deploy
hoses are installed on the affected thrust reversers). Airbus Canada
has notified the FAA that the list in Airbus Canada Limited Partnership
Service Bulletin BD500-783002, Issue 001, dated October 22, 2020,
contains incorrect part numbers for several serial numbers. Later
revisions of the service information contain correct part and serial
numbers. In addition, Table 1 to paragraph (h)(3) specifies the correct
part and serial numbers for the affected thrust reversers.
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-2021-46 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-2021-46 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
TCCA AD CF-2021-46 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
[[Page 60351]]
AD CF-2021-46 for compliance will be available at regulations.gov by
searching for and locating Docket No. FAA-2022-1236 after the FAA final
rule is published.
Costs of Compliance
The FAA estimates that this proposed AD would affect 8 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
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255........................... * $0 $255 $2,040
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost estimates for the parts specified in this
proposed AD.
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.
