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) 
2020-03-24, which applies certain Dassault Aviation Model MYSTERE-
FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. AD 2020-03-24 requires 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations. Since 
the FAA issued AD 2020-03-24, the FAA has determined that new or more 
restrictive airworthiness limitations are necessary. This proposed AD 
would continue to require the actions in AD 2020-03-24 and 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 September 
5, 2023.

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

specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Background

    The FAA issued AD 2020-03-24, Amendment 39-19848 (85 FR 11289, 
February 27, 2020) (AD 2020-03-24), for certain Dassault Aviation Model 
MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. AD 2020-03-24 
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-
0201, dated August 20, 2019 (EASA 2019-0201) (which corresponds to FAA 
AD 2020-03-24), to correct an unsafe condition.
    AD 2020-03-24 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. The FAA issued AD 2020-03-24 to 
address fatigue cracking, damage, and corrosion in principal structural 
elements, which could result in reduced structural integrity of the 
airplane. AD 2020-03-24 specifies that accomplishing the revision 
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), for 
Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes on which 
the SSIP [Supplemental Structural Inspection Program (Dassault Service 
Bulletin 730)] has been embodied into the airplane's existing 
maintenance or inspection program only. This proposed AD would 
therefore continue to allow that terminating action.

Actions Since AD 2020-03-04 Was Issued

    Since the FAA issued AD 2020-03-04, EASA superseded AD 2019-0201 
and issued EASA AD 2023-0062, dated March 20, 2023 (EASA AD 2023-0062) 
(referred to after this as the MCAI), for certain Dassault Aviation 
Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 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-2023-1495.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2023-0062. This service information 
specifies new or more restrictive airworthiness limitations for 
airplane structures and safe life limits.
    This proposed AD would also require Chapter 5-40-01, Airworthiness 
Limitations, of the Dassault Falcon 20 Retrofit 731 Maintenance Manual, 
Revision 10, dated January 1, 2019, which the Director of the Federal 
Register approved for incorporation by reference as of April 2, 2020 
(85 FR 11289, 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 section.

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 the requirements of AD 2020-03-04. 
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 2023-0062 already described, as proposed for incorporation by 
reference. Any differences with EASA AD 2023-0062 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 2023-0062 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2023-0062 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 2023-0062 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-
0062.

[[Page 46117]]

Service information required by EASA AD 2023-0062 for compliance will 
be available at regulations.gov by searching for and locating Docket 
No. FAA-2023-1495 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 57 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 2020-03-24 to be $7,650 (90 work-hours x $85 per work-
hour).
    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.
