Background Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF–2022– 39, dated July 18, 2022 (Transport Canada AD CF–2022–39) (also referred to after this as the MCAI), to correct an unsafe condition on certain Bombardier, Inc., Model BD–700–2A12 airplanes. The MCAI states that a disclosure letter from the supplier advised that certain pre-cooler clamp assemblies securing the ducting connection on the ECS precooler inlet assembly may not conform to drawing. If left uncorrected, the clamp may fail and cause excessive leakage at that connection. This could lead to increased operating temperatures in climate-controlled zones, or, in combination with other failures, a complete loss of the ECS. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–0170. 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 this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information described above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in the service information already described. Costs of Compliance Related Service Information Under 1 CFR Part 51 The FAA estimates that this AD, if adopted as proposed, would affect 12 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: The FAA reviewed Bombardier Service Bulletin 700–36–7504, dated June 27, 2022. This service information specifies procedures for inspecting the ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost ddrumheller on DSK120RN23PROD with PROPOSALS1 2 work-hours × $85 per hour = $170 ........................................................ The FAA has received no definitive data on which to base the cost estimates for the on-condition repairs 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 VerDate Sep<11>2014 17:29 Feb 23, 2023 Jkt 259001 Cost per product $60 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.

for this rulemaking.

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada AD CF-2022-39, dated July 18, 2022 (Transport 
Canada AD CF-2022-39) (also referred to after this as the MCAI), to 
correct an unsafe condition on certain Bombardier, Inc., Model BD-700-
2A12 airplanes. The MCAI states that a disclosure letter from the 
supplier advised that certain pre-cooler clamp assemblies securing the 
ducting connection on the ECS pre-cooler inlet assembly may not conform 
to drawing. If left uncorrected, the clamp may fail and cause excessive 
leakage at that connection. This could lead to increased operating 
temperatures in climate-controlled zones, or, in combination with other 
failures, a complete loss of the ECS.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-0170.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Bombardier Service Bulletin 700-36-7504, dated 
June 27, 2022. This service information specifies procedures for 
inspecting the pre-cooler clamps for non-conformance to the drawing and 
replacing non-conforming pre-cooler clamps. The clamp replacement 
includes a general visual inspection of non-conforming pre-cooler 
clamps around the silicone bellow for signs of damage, and corrective 
action including repair. This service information 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 this State of Design Authority, 
it has notified the FAA of the unsafe condition described in the MCAI 
and service information described above. The FAA is issuing this NPRM 
after determining that the unsafe condition described previously is 
likely to exist or develop on other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information already described.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 12 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                   Cost per
                  Labor cost                      Parts cost        product          Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170............             $60            $230  Up to $2,760.
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition repairs 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:

[[Page 11827]]

    (1) Is not a ``significant regulatory action'' under Executive

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]

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Bombardier, Inc.: Docket No. FAA-2023-0170; Project Identifier MCAI-
2022-00974-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by April 10, 2023.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc., Model BD-700-2A12 
airplanes, certificated in any category, serial numbers 70032, 70047 
through 70056 inclusive, 70058 through 70061 inclusive, and 70063 
through 70075 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 36, Pneumatic.

(e) Unsafe Condition

    This AD was prompted by a report that certain environmental 
control system (ECS) pre-cooler clamp assemblies may not conform to 
specifications. The FAA is issuing this AD to address possible 
excessive leakage caused by clamp failure. The unsafe condition, if 
not addressed, could result in increased operating temperatures in 
climate-controlled zones, or, in combination with other failures, a 
complete loss of the ECS.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Within 36 months after the effective date of this AD: Identify 
and replace, as applicable, the ECS pre-cooler clamps in accordance 
with the Accomplishment Instructions of Bombardier Service Bulletin 
700-36-7504, dated June 27, 2022.

(h) No Reporting Requirement

    Although Bombardier Service Bulletin 700-36-7504, dated June 27, 
2022, specifies to submit certain information to the manufacturer or 
discard affected clamps, this AD does not include that requirement.

(i) Additional AD Provisions

    The following provisions also apply to this AD:

York ACO Branch, FAA, has the authority to approve AMOCs for this
