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) 
2017-09-03 and AD 2018-20-07, which apply to all Dassault Aviation 
Model MYSTERE-FALCON 50 airplanes. AD 2017-09-03 and AD 2018-20-07 
require revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive airworthiness 
limitations. Since the FAA issued AD 2017-09-03 and AD 2018-20-07, the 
FAA has determined that new or more restrictive airworthiness 
limitations are necessary. This proposed AD would continue to require 
the actions in AD 2018-20-07 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 February 
27, 2023.

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

    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, Aerospace Engineer, Large Aircraft Section, International 
Validation Branch, FAA, 2200 South 216th St., Des Moines, WA 98198;

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 2018-20-07, Amendment 39-19441 (83 FR 49789, 
October 3, 2018) (AD 2018-20-07), for all Dassault Aviation Model 
MYSTERE-FALCON 50 airplanes. AD 2018-20-07 was prompted by an MCAI 
originated by EASA, which is the Technical Agent for the Member States 
of the European Union. EASA issued AD 2018-0026, dated January 30, 2018 
(EASA 2018-0026) (which corresponds to FAA AD 2018-20-07), to correct 
an unsafe condition.
    AD 2018-20-07 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate new and more 
restrictive maintenance requirements and airworthiness limitations. The 
FAA issued AD 2018-20-07 to address reduced structural integrity of the 
airplane. AD 2018-20-07 specifies that accomplishing the revision 
required by that AD terminates all requirements of AD 2017-09-03, 
Amendment 39-18865 (82 FR 21467, May 9, 2017) (AD 2017-09-03). AD 2018-
20-07 also specifies that it terminates the requirements of AD 2010-26-
05, Amendment 39-16544 (75 FR 79952, December 21, 2010) (AD 2010-26-05) 
and AD 2012-02-18, Amendment 39-16941 (77 FR 12175, February 29, 2012) 
(AD 2012-02-18) for certain Dassault Aviation Model MYSTERE-FALCON 50 
airplanes. AD 2012-02-18 has since been removed (84 FR 11640, March 28, 
2019). This proposed AD would therefore supersede AD 2017-09-03 and 
terminate the requirements of AD 2010-26-05 for Dassault Aviation Model 
MYSTERE-FALCON 50 airplanes only.

Actions Since AD 2018-20-07 Was Issued

    Since the FAA issued AD 2018-20-07, EASA superseded AD 2018-0026 
and issued EASA AD 2022-0166, dated August 11, 2022 (EASA AD 2022-0166) 
(referred to after this as the MCAI), for all Dassault Aviation Model 
MYSTERE-FALCON 50 airplanes. The MCAI states that new or more 
restrictive airworthiness limitations have been developed.
    The FAA is proposing this AD to address reduced structural 
integrity of the airplane. You may examine the MCAI in the AD docket at 
regulations.gov under Docket No. FAA-2023-0013.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2022-0166. 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, Airworthiness 
Limitations, DGT 113872, Revision 24, dated July 2017, of the Dassault 
Falcon 50/50EX Maintenance Manual, which the Director of the Federal 
Register approved for incorporation by reference as of November 7, 2018 
(83 FR 49789, October 3, 2018).
    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 the State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
described 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 requirements of AD 2018-20-07. 
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 2022-0166 already described, as proposed for incorporation by 
reference. Any differences with EASA AD 2022-0166 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

[[Page 2294]]

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 2022-0166 by 
reference in the FAA final rule. This proposed AD would, therefore, 
require compliance with EASA AD 2022-0166 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 2022-0166 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 2022-
0166. Service information required by EASA AD 2022-0166 for compliance 
will be available at regulations.gov by searching for and locating 
Docket No. FAA-2023-0013 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 239 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 2018-20-07 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.
