SUPPLEMENTARY INFORMATION: 

Background 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2021–30, dated September 7, 2021 

(TCCA AD CF–2021–30) (also referred 

to after this as the Mandatory 

Continuing Airworthiness Information, 

or the MCAI), to correct an unsafe 

condition for all Bombardier, Inc., 

Model BD–700–1A10 and BD–700– 

1A11 airplanes. You may examine the 

MCAI in the AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0470. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Bombardier, Inc., Model 

BD–700–1A10 and BD–700–1A11 

airplanes. The NPRM published in the 

Federal Register on April 26, 2022 (87 

FR 24476). The NPRM was prompted by 

reports that some oxygen box assemblies 

had their piston ejected during the mask 

deployment test. The NPRM proposed 

to require a one-time inspection of each 

passenger oxygen box dual manifold 

assembly to find and replace affected 

parts. The NPRM also proposed to 

prohibit installing affected parts. The 

FAA is issuing this AD to address a 

possible in-service piston ejection when 

used for emergency descent, smoke, or 

fire that may result in a high rate of 

oxygen leakage, which could 

prematurely deplete the oxygen for all 

passengers. See the MCAI for additional 

background information. 

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 

The FAA reviewed the relevant data 

and determined that air safety requires 

adopting this AD as proposed. 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. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. 

Related Service Information Under 1 

CFR Part 51 

Bombardier, Inc., has issued the 

following service information. 

• Service Bulletin 700–35–5004, 

Revision 02, dated August 27, 2021. 

• Service Bulletin 700–35–5502, 

dated August 27, 2021. 

• Service Bulletin 700–35–6004, 

Revision 05, dated August 27, 2021. 

• Service Bulletin 700–35–6502, 

dated August 27, 2021. 

This service information describes 

procedures for inspecting each 

passenger oxygen box dual manifold 

assembly to find affected parts, and 

replacing affected parts. These 

documents are distinct because they 


jspears on DSK121TN23PROD with RULES1
Federal Register / Vol. 87, No. 135 / Friday, July 15, 2022 / Rules and Regulations 42313 

apply to different airplane 

configurations. 

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 308 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this 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 .............................................................................................. $0 $85 $26,180 

The FAA estimates the following 

costs to do any necessary on-condition 

actions that would be required based on 

the results of any required actions. The 

FAA has no way of determining the 

number of aircraft that might need this 

on-condition action: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

Up to 34 work-hours × $85 per hour = $2,890 ....................................................................................................... Up to $1,700 Up to $4,590 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this 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 

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.

A321–111, –112, –131, –211, –212, 

–213, –231, and –232 airplanes. AD 

2018–13–08 required repetitive 

inspections for cracking of the radius of 

the front spar vertical stringers and the 

horizontal floor beam on frame (FR) 36, 

repetitive inspections for cracking of the 

fastener holes of the front spar vertical 

stringers on FR 36, and repair if 

necessary, and, for certain airplanes, a 

potential terminating action 

modification of the center wing box 

area. This AD was prompted by a 

determination that additional airplanes 

are subject to the unsafe condition. This 

AD revises the applicability by adding 

airplanes and retains the requirements 

of AD 2018–13–08; as specified in a 

European Union Aviation Safety Agency

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0241, 

dated November 8, 2021 (EASA AD 

2021–0241) (also referred to as the 

MCAI), to correct an unsafe condition 

for certain Airbus SAS Model A318 

series airplanes; Model A319–111, –112, 

–113, –114, –115, –131, –132, and –133 

airplanes; Model A320–211, –212, –214, 

–215, –216, –231, –232, and –233 

airplanes; and Model A321–111, –112, 

–131, –211, –212, –213, –231, and –232 

airplanes. Model A320–215 airplanes 

are not certificated by the FAA and are 

not included on the U.S. type certificate 

data sheet; this AD therefore does not 

include those airplanes in the 

applicability. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2018–13–08,
