AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to remove 

Airworthiness Directive (AD) 2010–26– 

05, which applies to certain Dassault 

Aviation Model Falcon 10 airplanes; 

Model FAN JET FALCON, FAN JET 

FALCON SERIES C, D, E, F, and G 

airplanes; Model MYSTERE–FALCON 

20–C5, 20–D5, 20–E5, and 20–F5 

airplanes; and all Model MYSTERE– 

FALCON 200 airplanes; Model FALCON 

2000 and FALCON 2000EX airplanes; 

Model MYSTERE–FALCON 50 and 

MYSTERE–FALCON 900 airplanes; and 

Model FALCON 900EX airplanes. AD 

2010–26–05 requires repetitive 

inspections for overpressure tightness 

on the pressurization control regulating 

valves and, if necessary, replacing the 

affected valve with a serviceable unit. 

AD 2010–26–05 is no longer necessary 

because the FAA has since issued ADs 

2021–04–20, 2020–02–13, 2020–03–24, 

2020–03–19, 2020–01–13, 2023–05–15, 

2023–04–10, 2023–02–13, 2023–04–18, 

and 2023–04–13 to address the unsafe 

condition. Accordingly, the FAA 

proposes to remove AD 2010–26–05. 

DATES: The FAA must receive comments 

on this proposed AD by October 13, 

2023.

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Tom Rodriguez, 

Aviation Safety Engineer, FAA, 1600 

Stewart Avenue, Suite 410, Westbury, 

NY 11590; telephone: 206–231–3226; 

email: tom.rodriguez@faa.gov. Any 

commentary that the FAA receives that 

is not specifically designated as CBI will 

be placed in the public docket for this 

rulemaking. 

Background 

The FAA issued AD 2010–26–05, 

Amendment 39–16544 (75 FR 79952, 

December 21, 2010) (AD 2010–26–05), 

for certain Dassault Aviation Model 

Falcon 10 airplanes; Model FAN JET 

FALCON, FAN JET FALCON SERIES C, 

D, E, F, and G airplanes; Model 

MYSTERE–FALCON 20–C5, 20–D5, 20– 

E5, and 20–F5 airplanes; and all Model 

FALCON 2000 and FALCON 2000EX

airplanes; Model MYSTERE–FALCON 

200 airplanes; Model MYSTERE– 

FALCON 50 and MYSTERE–FALCON 

900 airplanes, and Model FALCON 

900EX airplanes. AD 2010–26–05 was 

prompted by an MCAI originated by the 

European Union Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union. EASA issued AD 2008–0072, 

dated April 18, 2008 (EASA AD 2008– 

0072) (also referred to as the MCAI), to 

identify and correct an unsafe 

condition. 

AD 2010–26–05 requires repetitive 

inspections for overpressure tightness 

on the pressurization control regulating 

valves and, if necessary, replacing the 

affected valve with a serviceable unit. 

The FAA issued AD 2010–26–05 to 

address failure of the pressurization 

control regulating valve (overpressure 

capsule), which will affect the aircraft’s 

overpressure protection. 

Overpressurization can result in injury 

to the occupants and possible structural 

failure leading to loss of control of the 

airplane. 

Actions Since AD 2010–26–05 Was 

Issued 

Since the FAA issued AD 2010–26– 

05, the actions specified in the MCAI 

have been included in the airworthiness 

limitations section of the existing 

maintenance manual. EASA issued 

EASA AD 2008–0072–CN, dated 

October 5, 2020, which cancels EASA 

AD 2008–0072. The FAA issued the 

following ADs to address the unsafe 

condition by revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive maintenance requirements 

and airworthiness limitations, including 

the actions specified in AD 2010–26–05: 

• AD 2021–04–20, Amendment 39– 

21442 (86 FR 12802, March 5, 2021), 

which addresses the unsafe condition 

for Model Falcon 10 airplanes. 

• AD 2020–02–13, Amendment 39– 

19827 (85 FR 6744, February 6, 2020), 

which addresses the unsafe condition 

for Model FAN JET FALCON, FAN JET 

FALCON SERIES C, D, E, F, and G 

airplanes on which the supplemental 

structural inspection program (SSIP) has 

been incorporated into the airplane’s 

maintenance program. 

• AD 2020–03–24, Amendment 39– 

19848 (85 FR 11289, February 27, 2020), 

which addresses the unsafe condition 

for Model MYSTERE–FALCON 20–C5, 

20–D5, 20–E5, and 20–F5 airplanes on 

which the SSIP (Dassault Service 

Bulletin 730) has been embodied into 

the airplane’s existing maintenance or 

inspection program. 

•AD 2020–03–19, Amendment 39– 

19843 (85 FR 11280, February 27, 2020), 

which address the unsafe condition for 

Model MYSTERE–FALCON 20–C5, 20– 

D5, 20–E5, and 20–F5 airplanes, except 

those on which the SSIP (Dassault 

Service Bulletin 730) has been 

embodied into the airplane’s existing 

maintenance or inspection program. 

• AD 2020–01–13, Amendment 39– 

19819 (85 FR 5313, January 30, 2020), 

which addresses the unsafe condition 

for Model MYSTERE–FALCON 200 

airplanes. 

• AD 2023–05–15, Amendment 39– 

22384 (88 FR 22374, April 13, 2023), 

which addresses the unsafe condition 

for Model MYSTERE–FALCON 50 

airplanes. 

• AD 2023–04–10, Amendment 39– 

22357 (88 FR 20743, April 7, 2023), 

which addresses the unsafe condition 

for Model MYSTERE–FALCON 900 

airplanes. 

• AD 2023–02–13, Amendment 39– 

22320 (88 FR 8740, February 10, 2023), 

which addresses the unsafe condition 

for Model FALCON 900EX airplanes. 

• AD 2023–04–18, Amendment 39– 

22365 (88 FR 15607, March 14, 2023), 

which addresses the unsafe condition 

for Model FALCON 2000 airplanes. 

• AD 2023–04–13, Amendment 39– 

22360 (88 FR 20741, April 7, 2023), 

which addresses the unsafe condition 

for Model FALCON 2000EX airplanes. 

FAA’s Conclusions 

Upon further consideration, the FAA 

has determined that AD 2010–26–05 is 

no longer necessary. Accordingly, this 

proposed AD would remove AD 2010– 

26–05. Removal of AD 2010–26–05 

would not preclude the FAA from 

issuing another related action or commit 

the FAA to any course of action in the 

future. This proposed AD would remove 

all actions of AD 2010–26–05. 

Therefore, this proposed AD would 

terminate all requirements of AD 2010– 

26–05. 

Related Costs of Compliance 

This proposed AD would add no cost. 

This proposed AD would remove AD 

2010–26–05 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 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2023–04–15, which applies to certain 

Dassault Aviation Model FALCON 7X 

airplanes. AD 2023–04–15 requires 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations. Since the 

FAA issued AD 2023–04–15, the FAA 

has determined that new or more 

restrictive airworthiness limitations are 

necessary. This proposed AD would 

continue to require the actions in AD 

2023–04–15 and would require revising 

the existing maintenance or inspection 

program, as applicable, to incorporate 

new or more restrictive airworthiness 

limitations, as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is proposed for incorporation 

by reference (IBR). 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 October 13, 

2023. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR
