AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2020–03– 

19, which applied to certain Dassault 

Aviation Model MYSTERE–FALCON 

20–C5, 20–D5, 20–E5, and 20–F5 

airplanes. AD 2020–03–19 required 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations. This AD 

continues to require the actions in AD 

2020–03–19 and requires revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

additional new or more restrictive 

airworthiness limitations; as specified 

in a European Union Aviation Safety 

Agency (EASA) AD, which is 

incorporated by reference. This AD was 

prompted by a determination that new 

or more restrictive airworthiness 

limitations are necessary. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective November 2, 

2023. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2020–03–19, 

Amendment 39–19843 (85 FR 11280, 

February 27, 2020) (AD 2020–03–19). 

AD 2020–03–19 applied to certain 

Dassault Aviation Model MYSTERE– 

FALCON 20–C5, 20–D5, 20–E5, and 20– 

F5 airplanes. AD 2020–03–19 required 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations. The FAA 

issued AD 2020–03–19 to address 

fatigue cracking, damage, and corrosion 

in principal structural elements, which 

could result in reduced structural 

integrity of the airplane. 

The NPRM published in the Federal 

Register on July 11, 2023 (88 FR 44065). 

The NPRM was prompted by EASA AD 

2023–0058, dated March 16, 2023, 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union (referred to after this as 

the MCAI). The MCAI states that new or 

more restrictive airworthiness 

limitations have been developed. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2023–1403. 

In the NPRM, the FAA proposed to 

continue to require the actions in AD 

2020–03–19. In the NPRM, the FAA also 

proposed to require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate additional 

new or more restrictive airworthiness 

limitations, as specified in an EASA AD. 

The FAA is issuing this AD to address 

fatigue cracking, damage, and corrosion 

in principal structural elements. The 

unsafe condition, if not addressed, 

could result in reduced structural 

integrity of the airplane. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the cost to the public. 

Conclusion 

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 referenced above. The FAA 

reviewed the relevant data and 

determined that air safety requires 

adopting this AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on this 

product. Except for minor editorial 

changes, this AD is adopted as proposed 

in the NPRM. None of the changes will 

increase the economic burden on any 

operator.

66682 Federal Register / Vol. 88, No. 187 / Thursday, September 28, 2023 / Rules and Regulations 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed EASA AD 2023– 

0058. This service information specifies 

procedures for airworthiness limitations 

for safe life limits and certification 

maintenance requirements. 

This AD also requires Chapter 5–40– 

00, Airworthiness Limitations, of the 

Dassault Falcon 20 Retrofit 731 

Maintenance Manual, Revision 13, 

dated January 1, 2019, which the 

Director of the Federal Register 

approved for incorporation by reference 

as of April 2, 2020 (85 FR 11280, 

February 27, 2020). 

This service information 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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 56 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2020–03–19 to be $7,650 (90 workhours × $85 per work-hour). 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workhours per operator, although the agency 

recognizes that this number may vary 

from operator to operator. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. 

The FAA estimates the total cost per 

operator for the new actions to be 

$7,650 (90 work-hours × $85 per workhour). 

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 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, 

(2) Will not affect intrastate aviation 

in Alaska, and 

(3) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

this AD to address fatigue cracking, damage, 

and corrosion in principal structural 

elements. The unsafe condition, if not 

addressed, could result in reduced structural
