AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Dassault Aviation Model FALCON 2000 

and FALCON 2000EX airplanes. This 

AD was prompted by brake system 

failures during landing due to a brake 

servo-valve failure resulting from 

application of an inappropriate oil type 

during production and maintenance. 

This AD requires relocating affected 

servo-valves and revising the existing 

airplane flight manual (AFM) to provide 

temporary information necessary to 

operate airplanes fitted with at least one 

affected brake servo-valve, as specified 

in a European Union Aviation Safety 

Agency (EASA) AD, which is 

incorporated by reference. This AD also 

limits or prohibits the installation of 

affected brake servo-valves. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD becomes effective May 

31, 2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of May 31, 2022. 

The FAA must receive comments on 

this AD by June 27, 2022.

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Emergency AD 

2022–0068–E, dated April 14, 2022 

(EASA Emergency AD 2022–0068–E) 

(also referred to as the MCAI), to correct 

an unsafe condition for all Model 


lotter on DSK11XQN23PROD with RULES1
29218 Federal Register / Vol. 87, No. 93 / Friday, May 13, 2022 / Rules and Regulations 

FALCON 2000 and FALCON 2000EX 

airplanes. 

This AD was prompted by brake 

system failures during landing. 

Subsequent investigation determined 

the root cause to be a brake servo-valve 

failure. A batch of brake servo-valves 

has been identified during airplane 

production and maintenance with an 

internal oil type that does not meet the 

manufacturer’s cold temperature 

specifications, which can lead to their 

failure. The FAA is issuing this AD to 

prevent temporary failure of the brake 

servo-valves, which could lead to 

reduced braking performance during 

landing including degraded or 

dissymmetric braking, possibly resulting 

in reduced control of the airplane, 

lateral excursion of the runway, and 

consequent damage to the airplane. See 

the MCAI for additional background 

information. 

Related Service Information Under 1 

CFR Part 51 

EASA Emergency AD 2022–0068–E 

specifies procedures for, among other 

actions, relocating affected brake servovalves between the left-hand and righthand brake control systems to ensure 

that at least one of the two independent 

brake systems has no affected parts. 

EASA Emergency AD 2022–0068–E also 

specifies revising the existing AFM to 

provide temporary information 

necessary to operate airplanes fitted 

with at least one affected brake servovalve. EASA Emergency AD 2022– 

0068–E also limits or prohibits the 

future installation of affected brake 

servo-valves. 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 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 these same 

type designs. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in EASA Emergency 

AD 2022–0068–E described previously, 

except for any differences identified as 

exceptions in the regulatory text of this 

AD, and except as discussed under 

‘‘Differences Between this AD and the 

MCAI.’’ 

EASA Emergency AD 2022–0068–E 

requires operators to ‘‘inform all flight 

crews’’ of revisions to 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 

that operators furnish to pilots any 

changes to the AFM (for example, 14 

CFR 135.81(c)), and to ensure that pilots 

are familiar with the AFM (for example, 

14 CFR 91.505(a)). 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 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, EASA Emergency AD 

2022–0068–E is incorporated by 

reference in this AD. This AD requires 

compliance with EASA Emergency AD 

2022–0068–E 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 

Emergency AD 2022–0068–E 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 Emergency AD 2022– 

0068–E. Service information required by 

EASA Emergency AD 2022–0068–E for 

compliance will be available at https:// 

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0504 after this AD is published. 

Difference Between This AD and the 

MCAI 

The MCAI specifies to replace each 

affected brake servo-valve within 12 

months. The FAA is considering 

requiring that action, but the planned 

compliance time would allow enough 

time to provide notice and opportunity 

for prior public comment on the merits 

of the replacement. The FAA considers 

that this AD is interim action. The FAA 

may consider additional rulemaking 

that would require the replacement of 

affected brake servo-valves. 

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 forgoing notice 

and comment prior to adoption of this 

rule because a brake servo-valve failure 

due to application of an inappropriate 

oil could lead to reduced braking 

performance during landing including 

degraded or dissymmetric braking, 

possibly resulting in reduced control of 

the airplane, lateral excursion of the 

runway, and consequent damage to the 

airplane. Given the significance of the 

risk presented by this unsafe condition, 

it must be immediately addressed. 

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 forgo 

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 441 airplanes of U.S. registry. 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 87, No. 93 / Friday, May 13, 2022 / Rules and Regulations 29219 

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 

Up to 10 work-hours × $85 per hour = $850 ...................................................................... $11,690 $12,540 Up to $5,530,140. 

According to the manufacturer, some 

or all of the costs of this 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 

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.

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 the 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 modifies the 

route structure as necessary to preserve 

the safe and efficient flow of air traffic 

within the NAS. 

History 

The FAA published a notice of 

proposed rulemaking for Docket No. 

FAA–2021–0919, in the Federal 

Register (86 FR 61722; November 8, 

2021), amending T–215. Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal. One 

comment was received that did not 

pertain to the proposal. 

United States RNAV T-routes are 

published in paragraph 6011 of FAA 

Order JO 7400.11F, dated August 10, 

2021, and effective September 15, 2021, 

which is incorporated by reference in 14

Difference From the NPRM 

The FAA is adding the establishment 

of a new route, designated T–408, to this 

docket action. The establishment of T– 

408 was proposed in the Federal 

Register under Docket No. FAA–2021– 

0991 (86 FR 67373; November 26, 2021). 

No comments were received in response 

to the NPRM. However, the required 

documentation for T–408 was delayed 

and could not be completed in time to 

meet the planned chart date for Docket 

No. FAA–2021–0991. Therefore, T–408 

is being added to this final rule. 

The Rule 

This action amends 14 CFR part 71 by 

amending RNAV route T–215 by 

extending the route further to the north 

and southeast in the central United 


lotter on DSK11XQN23PROD with RULES1
