[Docket No. FAA-2020-1111; Product Identifier MCAI-2020-01374-T]
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
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.

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
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-
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-
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.
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
(1) Is not a "significant regulatory action" under Executive
(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.
