36274 Federal Register / Vol. 87, No. 116 / Thursday, June 16, 2022 / Proposed Rules 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

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. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

Bombardier, Inc.: Docket No. FAA–2022– 

0681; Project Identifier MCAI–2021– 

01292–T. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by August 1, 

2022. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Bombardier, Inc., 

Model BD–700–2A12 airplanes, certificated

dated January 13, 2021. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 35, Oxygen. 

(e) Unsafe Condition 

This AD was prompted by reports that 

significant water accumulation was 

discovered in the oxygen service 

compartment of multiple airplanes. The FAA 

is issuing this AD to address water ingress 

through oxygen service compartment access 

panels. If not addressed, the freeze/thaw 

cycle of accumulated water may damage 

oxygen connections inside the compartment, 

leading to oxygen leakage and risk of fire in 

the presence of an ignition source. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

Within 25 months after the effective date 

of this AD: Modify the oxygen service 

compartment door in accordance with Part A 

of the Accomplishment Instructions of 

Bombardier Service Bulletin 700–52–7508, 

Revision 1, dated January 13, 2021. 

(h) Credit for Previous Actions 

This paragraph provides credit for actions 

required by paragraph (g) of this AD, if those 

actions were performed before the effective 

date of this AD using Bombardier Service 

Bulletin 700–52–7508, dated September 4, 

2020.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to remove 

Airworthiness Directive (AD) 2020–25– 

03, which applies to all Airbus SAS 

Model A318, A319, A320, and A321 

series airplanes. AD 2020–25–03 

requires repetitive checks of the 

pressure gauges on the inflation 

reservoir of each emergency escape 

slide/raft to determine the amount of 

pressure, and applicable corrective 

actions. AD 2020–25–03 also provides 

optional terminating action for the 

repetitive checks. AD 2020–25–03 is no 

longer necessary because the unsafe 

condition no longer exists. Accordingly, 

the FAA proposes to remove AD 2020– 

25–03. 

DATES: The FAA must receive comments 

on this proposed AD by August 1, 2022.

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, previously issued AD 2020– 

0236, dated October 27, 2020 (EASA AD 

2020–0236) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or the MCAI), to correct an 

unsafe condition for all Airbus SAS 

Model A318 series airplanes; Model 

A319–111, –112, –113, –114, –115, 

–131, –132, –133, –151N, –153N, and 

–171N airplanes; Model A320–211, 

–212, –214, –215, –216, –231, –232, 

–233, –251N, –252N, –253N, –271N, 

–272N, and –273N airplanes; and Model 

A321 series airplanes. 

The FAA issued corresponding AD 

2020–25–03, Amendment 39–21345 (85 

FR 79415, December 10, 2020) (AD 

2020–25–03), for those airplanes except 

for Model A319–153N and A320–215 

airplanes, which are not included on the 

U.S. type certificate data sheet. AD 

2020–25–03 requires repetitive checks 

of the pressure gauges on the inflation 

reservoir of each emergency escape 

slide/raft to determine the amount of 

pressure, and applicable corrective 

actions. AD 2020–25–03 also provides 

optional terminating action for the 

repetitive checks. AD 2020–25–03 was 

prompted by a report of a loud bang 

heard during airplane boarding. A 

subsequent inspection revealed that one 

emergency escape slide/raft was found 

with zero reservoir pressure due to a 

burst rupture disk assembly in the 

inflation reservoir, which was probably 

caused by a manufacturing defect. The 

FAA issued AD 2020–25–03 to address 

insufficient reservoir pressure in an 

emergency escape slide/raft, which 

would prevent the deployment of the 

emergency escape slide/raft during an 

emergency, possibly resulting in injury 

to the occupants. 

Actions Since AD 2020–25–03 Was 

Issued 

Since the FAA issued AD 2020–25– 

03, EASA issued AD 2020–0236–CN, 

dated May 16, 2022, to cancel EASA AD 

2020–0236. EASA has advised the FAA 

that SAFRAN Aerosystems, the 

manufacturer of the affected parts, 

produced service information with 

instructions for replacement of the 

rupture disk during overhaul of the 

affected parts. EASA reports that no 

rupture disk failures have occurred in 

service or during overhaul. 

Consequently, new risk analysis 

determined that an unsafe condition no 

longer exists that would warrant AD 

action. 

On March 16, 2022, the FAA issued 

Special Airworthiness Information 

Bulletin (SAIB) 2022–06 to recommend 

replacement of the affected parts during 

overhaul. 

FAA’s Conclusions 

Upon further consideration, the FAA 

has determined that AD 2020–25–03 is 

no longer appropriate. Accordingly, this 

proposed AD would remove AD 2020– 

25–03. Removal of AD 2020–25–03 

would not preclude the FAA from 

issuing another related action or commit 

the FAA to any course of action in the 

future. 

Related Costs of Compliance 

This proposed AD would add no cost. 

This proposed AD would remove AD 

2020–25–03 from 14 CFR part 39; 

therefore, operators would no longer be 

required to show compliance with that 

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 


khammond on DSKJM1Z7X2PROD with PROPOSALS
36276 Federal Register / Vol. 87, No. 116 / Thursday, June 16, 2022 / Proposed Rules 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority. 

Regulatory Findings 

The FAA has 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 that the 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.

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–16–03, which applies to certain 

Airbus SAS Model A350–941 and –1041 

airplanes. AD 2021–16–03 requires an 

inspection for missing or incorrect 

application of the lightning strike edge 

glow sealant protection at certain 

locations in the wing tanks, and 

corrective action. Since the FAA issued 

AD 2021–16–03, a modification was 

developed to restore two independent 

layers of lightning strike protection on 

the wing upper cover. This proposed 

AD would continue to require the 

actions of AD 2021–16–03 and would 

require a modification to restore two 

independent layers of lightning strike 

protection, as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is proposed for incorporation 

by reference. The FAA is proposing this 

AD to address the unsafe condition on 

these products.
