Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This proposed AD was prompted by a determination that the baggage bay line fire extinguishing tube assembly might not have been installed with the correct torque. This proposed AD would require re-torqueing the baggage bay line fire extinguishing tube assembly to the correct torque values, and applying corrosion inhibiting compound on the discharge tubes. The FAA is proposing this AD to address the unsafe condition on these products.

FAA is proposing this AD to address the unsafe condition on these
products.

you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this NPRM. Submissions containing CBI should be sent to

Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2021-48, dated December 15,
2021 (CF-2021-48) (also referred to after this as the Mandatory
Continuing Airworthiness Information, or the MCAI), to correct an
unsafe condition for certain for certain Bombardier, Inc., Model BD-
700-2A12 airplanes. You may examine the MCAI in the AD docket at
<a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No.
FAA-2022-0687.
This proposed AD was prompted by a determination that the baggage
bay line fire extinguishing tube assembly might not have been installed
with the correct torque. Although the baggage bay is accessible to the
crew during flight with portable fire extinguishers, incorrect
torqueing of the baggage bay line fire extinguishing tube assembly
could lead to loss of the built-in fire extinguishing system for the
baggage bay. The FAA is proposing this AD to address improper
torqueing, which may lead to loss of the fire extinguishing
[[Page 36774]]
system, which could prevent extinguishing a fire and possibly result in
damage to the airplane and injury to occupants. See the MCAI for
additional background information.
Related Service Information Under 1 CFR Part 51
Bombardier Inc. has issued Service Bulletin 700-26-7503, dated
April 22, 2021. This service information describes procedures for re-
torqueing the baggage bay line fire extinguishing tube assembly to the
correct torque values, and applying corrosion inhibiting compound on
the discharge tubes. 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 the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
and service information 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
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 42 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
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............................. $5 $90 $3,780
----------------------------------------------------------------------------------------------------------------
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.

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:
Bombardier, Inc.: Docket No. FAA-2022-0687; Project Identifier MCAI-
2021-01405-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by August 5, 2022.
(b) Affected ADs
None.

70056, and 70062.
(d) Subject

protection.
(e) Unsafe Condition
This AD was prompted by a determination that the baggage bay
line fire extinguishing tube assembly might not have been installed

improper torqueing, which may lead to loss of the fire extinguishing
system, which could prevent extinguishing a fire and possibly result
in damage to the airplane and injury to occupants.

unless already done.
(g) Re-Torque Fire Extinguishing Tube Assembly
Within 28 months after the effective date of this AD: Re-torque

discharge tubes, in accordance with the Accomplishment Instructions
of Bombardier Service Bulletin 700-26-7503, dated April 22, 2021.
(h) No Reporting Requirement
Although Bombardier Service Bulletin 700-26-7503, dated April
22, 2021, specifies to submit certain information to the
manufacturer, this AD does not include that requirement.
