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) 
2018-24-03 which applies to all Dassault Aviation Model Falcon 10 
airplanes. AD 2018-24-03 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive maintenance requirements and airworthiness limitations. 
Since the FAA issued AD 2018-24-03, the FAA has determined that new or 
more restrictive airworthiness limitations are necessary. This proposed 
AD 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. 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 January 21, 
2021.

Discussion

    The FAA issued AD 2018-24-03, Amendment 39-19507 (83 FR 61523, 
November 30, 2018) (``AD 2018-24-03''), for all Dassault Aviation Model 
Falcon 10 airplanes. AD 2018-24-03 requires revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive maintenance requirements and airworthiness 
limitations. The FAA issued AD 2018-24-03 to address, among other 
things, fatigue cracking and damage in principal structural elements; 
such fatigue cracking and damage could result in reduced structural 
integrity of the airplane.

Actions Since AD 2018-24-03 Was Issued

    Since the FAA issued AD 2018-24-03, the FAA has determined that new 
or more restrictive airworthiness limitations are necessary.
    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0215, dated October 6, 2020 
(EASA AD 2020-0215) (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Dassault Aviation Model Falcon 10 airplanes.
    This proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
proposing this AD to address, among other things, fatigue cracking and 
damage in principal structural elements; such fatigue cracking and 
damage could result in reduced structural integrity of the airplane. 
See the MCAI for additional background information.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2020-0215 describes new or more restrictive airworthiness 
limitations for airplane structures and safe life limits.
    This AD would also require Section 5-40-00, Airworthiness 
Limitations, Revision 13, dated July 2017, of the Dassault Falcon 10 
Maintenance Manual, which the Director of the Federal Register approved 
for incorporation by reference as of January 4, 2019 (83 FR 61523, 
November 30, 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 the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    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, 
the FAA has been notified of the unsafe condition described in the MCAI 
and service information referenced above. The FAA is proposing this AD 
because the FAA has evaluated all pertinent information and determined 
an unsafe condition exists and is likely to exist or develop on other 
products of the same type design.

Proposed AD Requirements

    This proposed AD would retain the requirements of AD 2018-24-03. 
This proposed AD would also require revising the existing maintenance 
or inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations, which are specified in EASA AD 
2020-0215 described previously, as incorporated by reference. Any 
differences with EASA AD 2020-0215 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 according to paragraph 
(l)(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 initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2020-0215 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2020-0215 in its 
entirety, 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 the EASA AD 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 the EASA AD.
    Service information specified in EASA AD 2020-0215 that is required 
for compliance with EASA AD 2020-0215 will be available on the internet 
at https://www.regulations.gov by searching for and locating Docket No. 
FAA-2020-1111 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

[[Page 78810]]

and intervals are approved as an alternative method of compliance 
(AMOC) in accordance with the procedures specified in the AMOCs 
paragraph under ``Other FAA 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 proposed AD affects 60 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 2019-07-01 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. In the past, the agency has estimated that this action 
takes 1 work-hour per airplane. 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) 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.

    (1) The requirements specified in paragraphs (1) and (2) of EASA 
AD 2020-0215 do not apply to this AD.
    (2) Paragraph (3) of EASA AD 2020-0215 specifies revising ``the 
approved AMP'' within 12 months after its effective date, but this 
AD requires revising the existing maintenance or inspection program, 
as applicable, to incorporate the ``limitations, tasks and 
associated thresholds and intervals'' specified in paragraph (3) of 
EASA AD 2020-0215 within 90 days after the effective date of this 
AD.
    (3) The initial compliance time for doing the tasks specified in 
paragraph (3) of EASA AD 2020-0215 is at the applicable ``associated 
thresholds'' specified in paragraph (3) of EASA AD 2020-0215, or 
within 90 days after the effective date of this AD, whichever occurs 
later.

[[Page 78811]]

    (4) The provisions specified in paragraphs (4) and (5) of EASA 
AD 2020-0215 do not apply to this AD.
    (5) The ``Remarks'' section of EASA AD 2020-0215 does not apply 
to this AD.

(k) New Provisions for Alternative Actions and Intervals

    After the maintenance or inspection program has been revised as 
required by paragraph (i) of this AD, no alternative actions (e.g., 
inspections) or intervals are allowed unless they are approved as 
specified in the provisions of the ``Ref. Publications'' section of 
EASA AD 2020-0215.

(l) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Large Aircraft Section, International Validation Branch, FAA, has 
the authority to approve AMOCs for this AD, if requested using the
