AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–19–20, which applies to all 

Dassault Aviation Model FALCON 7X 

airplanes. AD 2021–19–20 requires 

amending the existing airplane flight 

manual (AFM) to incorporate a check 

and an operating limitation regarding 

the O2 saver function. Since the FAA 

issued AD 2021–19–20, it has been 

determined that the AFM update may 

not be sufficient to mitigate the risk of 

failed deactivation of the O2 saver 

function. This proposed AD would 

retain the requirements of AD 2021–19– 

20 and would require physical 

deactivation of the O2 saver function, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

proposed for incorporation by reference. 

This proposed AD would also limit the 

installation of affected parts under 

certain conditions. The FAA is 

proposing this AD to address the unsafe 

condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by July 25, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Background 

The FAA issued AD 2021–19–20, 

Amendment 39–21738 (86 FR 51604, 

September 16, 2021) (AD 2021–19–20), 

which applies to all Dassault Aviation 

Model FALCON 7X airplanes. AD 2021– 

19–20 requires amending the existing 

AFM to incorporate a check and an 

operating limitation regarding the O2

saver function. The FAA issued AD 

2021–19–20 to address defects on the 

piston hole associated with the O2 saver 

feature that may prevent efficient 

deactivation of the O2 saver function, 

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. 

Actions Since AD 2021–19–20 Was 

Issued 

Since the FAA issued AD 2021–19– 

20, Safran (the mask manufacturer) and 

Dassault identified the batch of 

flightcrew oxygen masks affected by the 

manufacturing defects. Additional 

safety analysis determined that the AFM 

amendment required by AD 2021–19–20 

may not be sufficient to mitigate the risk 

of failed deactivation of the O2 saver 

function in the long term. Consequently, 

Dassault issued service information 

providing instructions for mechanically 

deactivating the O2 saver function of 

affected flightcrew oxygen masks. 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0272, 

dated December 6, 2021 (EASA AD 

2021–0272) (also referred to as the 

MCAI), to correct an unsafe condition 

for all Dassault Aviation Model 

FALCON 7X airplanes. 

This proposed AD was prompted by 

reports of defects that may prevent 

efficient deactivation of the O2 saver 

function of crew oxygen masks and a 

determination that the AFM amendment 

required by AD 2021–19–20 may not be 

sufficient to mitigate the risk. The FAA 

is proposing this AD to address defects 

on the piston hole associated with the 

O2 saver feature that may prevent 

efficient deactivation of the O2 saver 

function, which could result in an 

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. 

Explanation of Retained Requirements 

Although this proposed AD does not 

explicitly restate the requirements of AD 

2021–19–20, this proposed AD would 

retain all of the requirements of AD 

2021–19–20. Those requirements are 

referenced in EASA AD 2021–0272, 

which, in turn, is referenced in 

paragraph (g) of this proposed AD. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0272 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; 

and for mechanically deactivating the 

O2 saver function of the affected parts 

(Safran flightcrew oxygen masks having 

part number MLD40–45–005 and serial 

number B150451 through B172005 

inclusive without the letter ‘‘R’’ after the 

serial number). EASA AD 2021–0272 

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 

These products have been approved 

by the aviation authority of another 

country and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the State 

of Design Authority, it has notified the 

FAA of the unsafe condition described 

in the MCAI referenced above. The FAA 

is issuing this NPRM after determining 

that the unsafe condition described 

previously is likely to exist or develop 

in other products of these same type 

designs. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

EASA AD 2021–0272 described 

previously, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

This proposed AD would also limit the 

installation of affected parts under 

certain conditions. 

EASA AD 2021–0272 requires 

operators to ‘‘inform all flight crews’’ of 

revisions to the AFM, and thereafter to 

‘‘operate the aeroplane accordingly.’’ 

However, this proposed AD would not 

specifically require those actions as 

those actions are already required by 

FAA regulations. FAA regulations 

require operators furnish to pilots any 

changes to the AFM (for example, 14 

CFR 121.137), and to ensure the pilots 

are familiar with the AFM (for example, 

14 CFR 91.505). As with any other 

flightcrew 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 any person operating a 

civil aircraft must comply with the 

operating limitations specified in the 

AFM. Therefore, including a 

requirement in this proposed AD to 

operate the airplane according to the 

revised 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, the FAA proposes to 

incorporate EASA AD 2021–0272 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2021–0272 

in its entirety through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Using common terms that are the same 

as the heading of a particular section in 

EASA AD 2021–0272 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 2021–0272. 

Service information required by EASA 

AD 2021–0272 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2022–0604 after the FAA final 

rule is published. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 20 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this proposed AD:

New proposed actions ................... 4 work-hours × $85 per hour = $340 ........................ 0 340 $6,800. 

According to the manufacturer, some 

or all of the costs of this proposed AD 

may be covered under warranty, thereby 

reducing the cost impact on affected 

individuals. The FAA does not control 

warranty coverage for affected 

individuals. As a result, the FAA has 

included all known costs in the cost 

estimate. 

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. 

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

Amendment 39–21738 (86 FR 51604, 

September 16, 2021) (AD 2021–19–20). 

(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 reports of 

defects on the piston hole associated with the 

O2 saver function that may prevent efficient 

deactivation of the O2 saver function and a 

determination that the airplane flight manual 

(AFM) amendment required by AD 2021–19– 

20 may not be sufficient to mitigate the risk 

of failed deactivation of the O2 saver 

function. The FAA is issuing this AD to 

address defects that may prevent efficient 

deactivation of the O2 saver function, which 

could result in an 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

compliance times specified in, and in 

accordance with, European Union Aviation 

Safety Agency (EASA) AD 2021–0272, dated 

December 6, 2021 (EASA AD 2021–0272). 

(h) Exceptions to EASA AD 2021–0272 

(1) Where EASA AD 2021–0272 refers to 

September 13, 2021 (the effective date of 

EASA AD 2021–0202–E), this AD requires 

using September 16, 2021 (the effective date 

of AD 2021–19–20). 

(2) Where EASA AD 2021–0272 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(3) Where paragraph (1) of EASA AD 2021– 

0272 requires operators to ‘‘inform all flight 

crews, and thereafter operate the aeroplane 

accordingly,’’ this AD does not require those 

actions as they are already required by 

existing FAA operating regulations. 

(4) The ‘‘Remarks’’ section of EASA AD 

2021–0272 does not apply to this AD. 

(i) No Reporting Requirement 

Although the service information 

referenced in EASA AD 2021–0272 specifies 

to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(j) Additional FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Large Aircraft

Airworthiness Directives; 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 Bombardier, Inc., Model CL– 

600–1A11 (600), CL–600–2A12 (601), 

and CL–600–2B16 (601–3A, 601–3R, 

and 604 Variants) airplanes. This 

proposed AD was prompted by a report 

that some rudder power control unit 

(PCU) load limiters were found in 

service with the crimping missing from 

the end cap; therefore, the pilot 

command from the load limiter might 

not transmit correctly. This proposed 

AD would require a one-time inspection 

of the rudder PCU load limiters for 

correct crimping of the end cap, and 

replacing any defective rudder PCU load 

limiter. For certain airplanes, this 

proposed AD would also require 

repetitive testing of the rudder PCU load 

limiter for correct functioning, and 

applicable corrective actions. The FAA 

is proposing this AD to address the 

unsafe condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by July 25, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

https://www.regulations.gov. Follow the 

instructions for submitting comments.
