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 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 retorqueing 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. 

DATES: The FAA must receive comments 

on this proposed AD by August 5, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

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 https://www.regulations.gov 

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 


jspears on DSK121TN23PROD with PROPOSALS1
36774 Federal Register / Vol. 87, No. 118 / Tuesday, June 21, 2022 / Proposed Rules 

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

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

1 work-hour × $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 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701.
