SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0181, 

dated July 30, 2021 (EASA AD 2021– 

0181) (also referred to as the MCAI), to 

correct an unsafe condition for all 

Airbus SAS Model A300 B2–1C, B2K– 

3C, B2–203, B4–2C, B4–103, and B4– 

203 airplanes. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Airbus SAS Model A300 

B2–1C, B2K–3C, B2–203, B4–2C, B4– 

103, and B4–203 airplanes. The NPRM 

published in the Federal Register on 

December 17, 2021 (86 FR 71592). The 

NPRM was prompted by a 

determination that new or more 

restrictive airworthiness limitations 

related to pylon maintenance are 

necessary. The NPRM proposed to 

require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations for 

pylon maintenance, as specified in 

EASA AD 2021–0181. 

The FAA is issuing this AD to address 

fatigue cracking, damage, and corrosion 

in principal structural elements; such 

fatigue cracking, damage, and corrosion 

could result in reduced structural 

integrity of the airplane. 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 

EASA AD 2021–0181 specifies new or 

more restrictive airworthiness 

limitations for pylon maintenance. This 

material 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 1 airplane of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workhours per operator, although the agency 

recognizes that this number may vary 

from operator to operator. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. Therefore, the agency 

estimates the average total cost per 

operator to be $7,650 (90 work-hours × 

$85 per work-hour). 

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: 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 87, No. 39 / Monday, February 28, 2022 / Rules and Regulations 10957 

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.

Airworthiness Directives; AVOX 

System Inc. (Formerly Scott Aviation) 

Oxygen Cylinder and Valve 

Assemblies and Oxygen Valve 

Assemblies 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

AVOX System Inc. (formerly Scott 

Aviation) oxygen cylinder and valve 

assemblies, and oxygen valve 

assemblies, installed on but not limited 

to various transport airplanes. This AD 

was prompted by reports of cylinder 

and valve assemblies having oxygen 

leakage from the valve assembly vent 

hole, caused by the absence of a guide 

that maintains appropriate spacing 

between certain parts. This AD requires 

an inspection of the oxygen valve 

assemblies, and oxygen cylinder and 

valve assemblies, to determine the serial 

number of the valve, cylinder, and 

entire assembly. For assemblies and 

parts with certain serial numbers, this 

AD requires a detailed inspection for 

correct spacing of the gap between the 

bottom of the packing retainer and top 

of the valve body on the assemblies, and 

replacement of assemblies having 

unacceptable gaps. The FAA is issuing 

this AD to address the unsafe condition 

on these products. 

DATES: This AD is effective April 4, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of April 4, 2022.

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 AVOX System Inc. 

(formerly Scott Aviation) oxygen 

cylinder and valve assemblies, and 

oxygen valve assemblies, installed on 

but not limited to various transport 

airplanes. The NPRM published in the 

Federal Register on May 1, 2020 (85 FR 

25353). The NPRM was prompted by 

reports of cylinder and valve assemblies 

having oxygen leakage from the valve 

assembly vent hole, caused by the 

absence of a guide that maintains 

appropriate spacing between certain 

parts. In the NPRM, the FAA proposed 

to require an inspection of the oxygen 

valve assemblies, and oxygen cylinder 

and valve assemblies, to determine the 

serial number of the valve, cylinder, and 

entire assembly. For assemblies and 

parts with certain serial numbers, the 

NPRM proposed to require a detailed 

inspection for correct spacing of the gap 

between the bottom of the packing 

retainer and top of the valve body on the 

assemblies, and replacement of 

assemblies having unacceptable gaps 

(removing affected assemblies and 

installing serviceable assemblies). The 

NPRM also proposed to require 

reporting and returning of affected parts 

to the manufacturer. The FAA is issuing 

this AD to address oxygen leakage from 

the cylinder, which could result in 

decreased or insufficient oxygen supply 

during a depressurization event; and 

heating or flow friction, which could 

cause an ignition event in the valve 

assembly. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

one commenter, Air Line Pilots 

Association, International (ALPA), who 

supported the NPRM without change. 

The FAA received additional 

comments from five commenters, 

including American Airlines (AAL), 

Delta Air Lines (DAL), FedEx Express 

(FedEx), United Airlines (UAL), and an 

individual. The following presents the 

comments received on the NPRM and 

the FAA’s response to each comment. 

Request To Revise Applicability 

AAL and UAL suggested revising the 

applicability statement to include more 

aircraft manufacturers and models. AAL 

suggested adding all airplane models 

that affected assemblies could be 

installed on, in particular, Boeing Model 

737–NG (Next Generation models are 

737–600, –700, –700C, –800, –900, and 

–900ER series), 737–MAX, 777–200, and 

777–300 series airplanes. UAL also 

suggested adding Model 737–NG 

airplanes. AAL stated that the 

applicability statement as proposed in 

the NPRM could mislead operators into 

believing that the AD would apply only 

to the airplanes identified in paragraphs 

(c)(1) through (12) of the AD. UAL 

believed the suggested change will be 

beneficial and assist operators in 

determining if their fleets are affected.
