Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

[[Page 56579]]

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model BD-700-2A12 airplanes. This 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 AD requires 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 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective October 20, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 20, 
2022.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2022-0687; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains this final rule, the mandatory continuing airworthiness 
information (MCAI), any comments received, and other information. The

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Bombardier, 
Inc., Model BD-700-2A12 airplanes. The NPRM published in the Federal 
Register on June 21, 2022 (87 FR 36773). The NPRM was prompted by TCCA 
AD CF-2021-48, dated December 15, 2021, issued by Transport Canada 
Civil Aviation (TCCA), which is the aviation authority for Canada 
(referred to after this as the MCAI). The MCAI states that the baggage 
bay line fire extinguishing tube assembly may not have been installed 
in production 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.
    In the NPRM, the FAA proposed to 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 issuing this AD to address the unsafe condition on these 
products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-0687.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    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 
referenced above. The FAA reviewed the relevant data and determined 
that air safety requires adopting this AD as proposed. Accordingly, the 
FAA is issuing this AD to address the unsafe condition on this product. 
Except for minor editorial changes, this AD is adopted as proposed in 
the NPRM. None of the changes will increase the economic burden on any 
operator.

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.

Costs of Compliance

    The FAA estimates that this AD affects 42 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will 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 Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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:

2022-18-10 Bombardier, Inc.: Amendment 39-22161; Docket No. FAA-
2022-0687; Project Identifier MCAI-2021-01405-T.

(a) Effective Date

    This airworthiness directive (AD) is effective October 20, 2022.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc., Model BD-700-2A12 
airplanes, certificated in any category, serial numbers (S/Ns) 70006 
through 70044 inclusive, S/Ns 70046 through 70052 inclusive, and S/
Ns 70055, 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 
with the correct torque. The FAA is issuing this AD to address 
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 
the baggage bay line fire extinguishing tube assembly to the correct 
torque values, and apply corrosion inhibiting compound on the 
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.

(i) Other AD Provisions

    The following provisions also apply to this AD:
