Airworthiness Directives; MHI RJ 

Aviation ULC (Type Certificate 

Previously Held by Bombardier, Inc.) 

Airplanes 

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 MHI RJ Aviation ULC Model 

CL–600–2C10 (Regional Jet Series 700, 

701 & 702); CL–600–2C11 (Regional Jet 

Series 550); CL–600–2D15 (Regional Jet 

Series 705); CL–600–2D24 (Regional Jet 

Series 900); and CL–600–2E25 (Regional 

Jet Series 1000) airplanes. This 

proposed AD was prompted by 

laboratory tests that showed that the 

oxygen tubes of the crew oxygen system 

may be contaminated with lubricants, as 

a result of the manufacturing and 

cleaning procedures used. This 

proposed AD would require cleaning 

and flushing the crew oxygen system. 

The FAA is proposing this AD to 

address the unsafe condition on these 

products.

Background 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2022–06, dated February 28, 2022 

(TCCA AD CF–2022–06) (also referred 

to after this as the Mandatory 

Continuing Airworthiness Information, 

or the MCAI), to correct an unsafe 

condition for certain MHI RJ Aviation 

ULC Model CL–600–2C10 (Regional Jet 

Series 700, 701 & 702); CL–600–2C11 

(Regional Jet Series 550); CL–600–2D15 

(Regional Jet Series 705); CL–600–2D24 

(Regional Jet Series 900); and CL–600– 

2E25 (Regional Jet Series 1000) 

airplanes. You may examine the MCAI 

in the AD docket at https:// 

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0521. 

This proposed AD was prompted by 

laboratory tests that showed that the 

oxygen tubes of the crew oxygen system 

may be contaminated with lubricants, as 

a result of the inadvertent use of a nonconforming aqueous degreasing process 

for oxygen line flushing and cleaning 

during the manufacturing process. The 

FAA is proposing this AD to address the 

contaminated oxygen tubes of the crew 

oxygen system, which could lead to a 


khammond on DSKJM1Z7X2PROD with PROPOSALS
29842 Federal Register / Vol. 87, No. 95 / Tuesday, May 17, 2022 / Proposed Rules 

fire within the oxygen tubes, or a health 

hazard related to the inhalation of 

lubricant fumes when the masks are in 

use. See the MCAI for additional 

background information. 

Related Service Information Under 1 

CFR Part 51 

MHI RJ has issued Service Bulletin 

670BA–35–016, Revision B, dated 

December 17, 2021. This service 

information describes procedures for 

low-pressure and high-pressure cleaning 

of the crew oxygen tubes. The tasks 

include cleaning the end fittings and 

threads, cleaning the inner wall of the 

tubes with solvent, and flushing the 

inner wall of the tubes with nitrogen. 

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 34 

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 

51 work-hours × $85 per hour = $4,335 ............................................................................ Up to $1,240 ..... Up to $5,575 .... Up to $189,550. 

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.
