Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Emergency AD 

2021–0202–E, dated September 9, 2021 

(EASA Emergency AD 2021–0202–E) 

(also referred to as the MCAI), to correct 

an unsafe condition for all Dassault 

Aviation Model FALCON 7X airplanes. 

EASA subsequently issued EASA AD 

2021–0202R1, dated September 10, 2021 

(EASA AD 2021–0202R1) to address an 

incorrect reference to a non-existing part 

number within the definition of the 

affected part. 

This AD was prompted by a report of 

plastic molding burrs and defects found 

on the piston hole associated with the 

O2 saver feature during production of 

certain SAFRAN flightcrew oxygen 

masks. The O2 saver function allows the 

flightcrew to wear the oxygen mask with 

limited oxygen consumption to save 

oxygen by delivering it only when 

needed, either automatically in case of 

depressurization, or manually by 

switching the 100% or EMERG mode 

button. Defects on the piston hole may 

prevent efficient deactivation of the O2

saver function. The FAA is issuing this 

AD to address this condition, which 

could lead to inadequate oxygen supply 

to the flightcrew in case of 

decompression of the airplane or smoke 

or fire in the flight deck. See the MCAI 

for additional background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0202R1 specifies 

procedures for amending the existing 

AFM to incorporate a specific check to 

ensure that the O2 saver function is not 

activated and an operating limitation to 

prevent use of the O2 saver function. 

EASA AD 2021–0202R1 also limits the 

installation of affected parts under 

certain conditions. 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. 

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 this State of 

Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI described above. The FAA 

is issuing this AD after determining that 

the unsafe condition described 

previously is likely to exist or develop 

on other products of the same type 

design. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in EASA AD 2021– 

0202R1 described previously, except for 

any differences identified as exceptions 

in the regulatory text of this AD. 

EASA AD 2021–0202R1 requires 

operators to ‘‘inform all flight crews’’ of 

amendments to the AFM, and thereafter 

to ‘‘operate the aeroplane accordingly.’’ 

However, this AD does not specifically 

require those actions as they are already 

required by FAA regulations. FAA 

regulations require operators furnish to 

pilots any changes to the AFM (e.g., 14 

CFR 121.137), and to ensure that pilots 

are familiar with the AFM (e.g., 14 CFR 

91.505). As with any other training 

requirement, training on the updated 

AFM content is tracked by the operators 

and recorded in each pilot’s training 

record, which is available for the FAA 

to review. FAA regulations also require 

pilots to follow the procedures in the 

existing AFM including all updates. 14 

CFR 91.9 requires that no person may 

operate a civil aircraft without 

complying with the operating 

limitations specified in the AFM. 

Therefore, including a requirement in 

this AD to operate the airplane 

according to the amended AFM would 

be redundant and unnecessary. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, EASA AD 2021– 

0202R1 is incorporated by reference in 

this AD. This AD requires compliance 

with EASA AD 2021–0202R1 in its 

entirety through that incorporation, 

except for any differences identified as 

exceptions in the regulatory text of this 

AD. Using common terms that are the 

same as the heading of a particular 

section in EASA AD 2021–0202R1 does 

not mean that operators need comply 

only with that section. For example, 

where the AD requirement refers to ‘‘all 

required actions and compliance times,’’ 

compliance with this AD requirement is 

not limited to the section titled 

‘‘Required Action(s) and Compliance 

Time(s)’’ in EASA AD 2021–0202R1. 

Service information required by EASA 

AD 2021–0202R1 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2021–0790 after this AD is 

published. 

Interim Action 

The FAA considers this AD interim 

action. If final action is later identified, 

the FAA might consider further 

rulemaking then. 

FAA’s Justification and Determination 

of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) (5 

U.S.C. 551 et seq.) authorizes agencies 

to dispense with notice and comment 

procedures for rules when the agency, 

for ‘‘good cause,’’ finds that those 

procedures are ‘‘impracticable, 

unnecessary, or contrary to the public 

interest.’’ Under this section, an agency, 

upon finding good cause, may issue a 

final rule without providing notice and 

seeking comment prior to issuance. 

Further, section 553(d) of the APA 

authorizes agencies to make rules 

effective in less than thirty days, upon 

a finding of good cause. 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies foregoing notice 

and comment prior to adoption of this 

rule because failure to deactivate the O2

51606 Federal Register / Vol. 86, No. 177 / Thursday, September 16, 2021 / Rules and Regulations 

saver function could lead to inadequate 

oxygen supply to the flightcrew in case 

of decompression of the airplane or 

smoke or fire in the flight deck. 

Accordingly, notice and opportunity for 

prior public comment are impracticable 

and contrary to the public interest 

pursuant to 5 U.S.C. 553(b)(3)(B). 

In addition, the FAA finds that good 

cause exists pursuant to 5 U.S.C. 553(d) 

for making this amendment effective in 

less than 30 days, for the same reasons 

the FAA found good cause to forego 

notice and comment. 

Regulatory Flexibility Act (RFA) 

The requirements of the RFA do not 

apply when an agency finds good cause 

pursuant to 5 U.S.C. 553 to adopt a rule 

without prior notice and comment. 

Because the FAA has determined that it 

has good cause to adopt this rule 

without notice and comment, RFA 

analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 20 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 Up to $1,700. 

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, 

and 

(2) Will not affect intrastate aviation 

in Alaska. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation

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: 

2021–19–20 Dassault Aviation: 

Amendment 39–21738; Docket No. 

FAA–2021–0790; Project Identifier 

MCAI–2021–01007–T. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective September 16, 2021. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Dassault Aviation 

Model FALCON 7X airplanes, certificated in 

any category. 

Note 1 to paragraph (c): Model FALCON 

7X airplanes with Dassault modification 

M1000 incorporated are commonly referred 

to as ‘‘Model FALCON 8X’’ as a marketing 

designation. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 35, Oxygen. 

(e) Unsafe Condition 

This AD was prompted by report of defects 

on the piston hole associated with the O2

saver feature that may prevent efficient 

deactivation of the O2 saver function. The 

FAA is issuing this AD to address this 

condition, which could lead to inadequate 

oxygen supply to the flightcrew in case of 

decompression of the airplane or smoke or 

fire in the flight deck. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, EASA AD 2021–0202R1, 

dated September 10, 2021 (EASA AD 2021– 

0202R1). 

(h) Exceptions to EASA AD 2021–0202R1 

(1) Where EASA AD 2021–0202R1 refers to 

its effective date, this AD requires using the 

effective date of this AD. 

(2) Paragraph (1) of EASA AD 2021– 

0202R1 specifies amending ‘‘the applicable 

AFM [airplane flight manual],’’ but this AD 

requires amending the applicable existing

(3) Whereas paragraph (1) of EASA AD 

2021–0202R1 requires operators to ‘‘inform 

all flight crews’’ of the AFM amendments, 

and thereafter to ‘‘operate the aeroplane 

accordingly,’’ this AD does not specifically 

require those actions as they are already 

required by FAA regulations. 

(4) This AD does not mandate compliance 

with the ‘‘Remarks’’ section of EASA AD 

2021–0202R1. 

(i) Special Flight Permit 

Special flight permits may be issued in 

accordance with 14 CFR 21.197 and 21.199 

to operate the airplane to a location where 

the actions can be performed, provided the 

flight is nonpressurized.

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it amends the 

Class D airspace, the Class E airspace 

area designated as an extension to Class 

D airspace, and the Class E airspace 

extending upward from 700 feet above 

the surface at Scott AFB/MidAmerica 

St. Louis Airport, Belleville, IL, to 

support instrument flight rule 

operations at this airport. 

History 

The FAA published a notice of 

proposed rulemaking (NPRM) in the 

Federal Register (86 FR 33586; June 25, 

2021) for Docket No. FAA–2021–0477 to 

amend the Class D and Class E airspace 

at Scott AFB/MidAmerica St. Louis 

Airport, Belleville, IL. Interested parties 

were invited to participate in this 

rulemaking effort by submitting written 

comments on the proposal to the FAA. 

No comments were received. 

Class D and E airspace designations 

are published in paragraph 5000, 6004, 

and 6005, respectively, of FAA Order JO 

7400.11F, dated August 10, 2021, and 

effective September 15, 2021, which is 

incorporated by reference in 14 CFR 

71.1. The Class D and E airspace 

designations listed in this document 

will be published subsequently in the 

order. 

Availability and Summary of 

Documents for Incorporation by 

Reference 

This document amends FAA Order JO 

7400.11F, Airspace Designations and

Differences From the NPRM 

Subsequent to the publication of the 

NPRM, the FAA discovered a 

typographic error in the Class E airspace 

extending upward from 700 feet above 

the surface to at Scott AFB/MidAmerica 

St. Louis Airport airspace legal 

description. In the northeast extension, 

the extension should extend from the 

7.4-mile radius vice 4.9-mile. 

Additionally, it was discovered that the 

extension proposed to be added 

southeast of the airport is captured by 

another extension and is therefore not 

required. As these changes do not affect
