[Docket No. FAA-2023-1403; Project Identifier MCAI-2023-00479-T]
RIN 2120-AA64


Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2020-03-19, which applies to certain Dassault Aviation Model MYSTERE-
FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. AD 2020-03-19 requires 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations. Since 
the FAA issued AD 2020-03-19, the FAA has determined that new or more 
restrictive airworthiness limitations are necessary. This proposed AD 
would continue to require the actions in AD 2020-03-19 and would 
require 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 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 August 25, 
2023.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

this proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

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, 1600 Stewart Avenue, Suite 410, 
Westbury, NY 11590; phone: 206-231-3226; email: [email protected]. 
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 2020-03-19, Amendment 39-19843 (85 FR 11280, 
February 27, 2020) (AD 2020-03-19), for certain Dassault Aviation Model 
MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. AD 2020-03-19 
was prompted by an MCAI originated by EASA, which is the Technical 
Agent for the Member States of the European Union. EASA issued AD 2019-
0200R1, dated August 29, 2019 (EASA AD 2019-0200R1) (which corresponds 
to FAA AD 2020-03-19), to correct an unsafe condition.

[[Page 44066]]

    AD 2020-03-19 requires 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. AD 2020-03-19 specifies that accomplishing the actions 
required by that AD terminates the requirements of paragraph (g)(1) of 
AD 2010-26-05, Amendment 39-16544 (75 FR 79952, December 21, 2010) (AD 
2010-26-05) only for Dassault Aviation Model MYSTERE-FALCON 20-C5, 20-
D5, 20-E5, and 20-F5 airplanes on which the Supplemental Structural 
Inspection Program has not been embodied into the airplane's existing 
maintenance or inspection program. This proposed AD would therefore 
continue to allow that terminating action.

Actions Since AD 2020-03-19 Was Issued

    Since the FAA issued AD 2020-03-19, EASA superseded AD 2019-0200R1 
and issued EASA AD 2023-0058, dated March 16, 2023 (EASA AD 2023-0058) 
(referred to after this as the MCAI), for certain Dassault Aviation 
MYSTERE-FALCON 20-( )5 series airplanes. The MCAI states that new or 
more restrictive airworthiness limitations have been developed.
    The FAA is proposing this AD to address fatigue cracking, damage, 
and corrosion in principal structural elements, which could result in 
reduced structural integrity of the airplane. You may examine the MCAI 
in the AD docket at regulations.gov under Docket No. FAA-2023-1403.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2023-0058. This service information 
describes procedures for airworthiness limitations for safe life limits 
and certification maintenance requirements.
    This proposed AD would also require 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 material is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in ADDRESSES.

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 and 
service information 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 the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would retain all of the requirements of AD 2020-
03-19. This proposed AD would also require revising the existing 
maintenance or inspection program, as applicable, to incorporate 
additional new or more restrictive airworthiness limitations, which are 
specified in EASA AD 2023-0058 already described, as proposed for 
incorporation by reference. Any differences with EASA AD 2023-0058 are 
identified as exceptions in the regulatory text of this AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance (AMOC) according to 
paragraph (m)(1) of this proposed AD.

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 2023-0058 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2023-0058 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 2023-0058 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 2023-
0058. Service information required by EASA AD 2023-0058 for compliance 
will be available at regulations.gov by searching for and locating 
Docket No. FAA-2023-1403 after the FAA final rule is published.

Airworthiness Limitation ADs Using the New Process

    The FAA's process of incorporating by reference MCAI ADs as the 
primary source of information for compliance with corresponding FAA ADs 
has been limited to certain MCAI ADs (primarily those with service 
bulletins as the primary source of information for accomplishing the 
actions required by the FAA AD). However, the FAA is now expanding the 
process to include MCAI ADs that require a change to airworthiness 
limitation documents, such as airworthiness limitation sections.
    For these ADs that incorporate by reference an MCAI AD that changes 
airworthiness limitations, the FAA requirements are unchanged. 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document. The airworthiness limitations must 
be followed according to 14 CFR 91.403(c) and 91.409(e).
    The previous format of the airworthiness limitation ADs included a 
paragraph that specified that no alternative actions (e.g., 
inspections) or intervals may be used unless the actions and intervals 
are approved as an AMOC in accordance with the procedures specified in 
the AMOCs paragraph under ``Additional AD Provisions.'' This new format 
includes a ``New Provisions for Alternative Actions and Intervals'' 
paragraph that does not specifically refer to AMOCs, but operators may 
still request an AMOC to use an alternative action or interval.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 56 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2020-03-19 to be $7,650 (90 work-hours x $85 per work-
hour).

[[Page 44067]]

    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours 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 proposed 
actions to be $7,650 (90 work-hours x $85 per work-hour).

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.
