(a) EFFECTIVE DATE

    This airworthiness directive (AD) is effective April 9, 2021.

(b) AFFECTED ADS

    This  AD  replaces  AD 2018-24-03,  Amendment  39-19507  (83 FR 61523,
    November 30, 2018) (AD 2018-24-03).

(c) APPLICABILITY

    This AD applies  to  all  Dassault Aviation Model Falcon 10 airplanes,
    certificated in any category.

(d) SUBJECT

    Air Transport Association (ATA) of America Code 05,  Time Limits/Main-
    tenance Checks.

(e) REASON

    This AD was prompted by  a determination that new or  more restrictive
    airworthiness limitations are necessary. The FAA is issuing 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.

(f) COMPLIANCE

    Comply with this AD within the compliance times specified,  unless al-
    ready done.

(g) RETAINED MAINTENANCE OR INSPECTION PROGRAM REVISION, WITH NO CHANGES

    This paragraph restates the requirements of paragraph (g)  of AD 2018-
    24-03,  with no changes.  Within 90 days  after  January 4, 2019  (the
    effective date of AD 2018-24-03),  revise the existing maintenance  or
    inspection program,  as applicable,  to  incorporate  Section 5-40-00,
    Airworthiness  Limitations,  Revision  13,  dated  July 2017,  of  the
    Dassault Falcon 10 Maintenance Manual (Section 5-40-00).  The  initial
    compliance time  for  accomplishing  the  actions is at the applicable
    time specified in Section 5-40-00;  or within 90 days after January 4,
    2019; whichever occurs later.

(h) RETAINED RESTRICTIONS ON ALTERNATIVE ACTIONS AND INTERVALS  WITH A NEW
    EXCEPTION

    This paragraph restates the requirements of paragraph (h)  of AD 2018-
    24-03,  with a new exception.  Except as required  by paragraph (i) of
    this AD,  after the maintenance or inspection program has been revised
    as required by paragraph (g) of this AD, no alternative actions (e.g.,
    inspections) or intervals may be used unless the actions  or intervals
    are approved as an alternative method of compliance  (AMOC) in accord-
    ance with the procedures specified in paragraph (l)(1) of this AD.

(i) NEW MAINTENANCE OR INSPECTION PROGRAM REVISION

    Except as specified in paragraph (j) of this AD:  Comply with  all re-
    quired actions and compliance times specified in,  and  in  accordance
    with, European Union Aviation Safety Agency (EASA) AD 2020-0215, dated
    October 6, 2020 (EASA AD 2020-0215).  Accomplishing the maintenance or
    inspection program revision required  by this paragraph terminates the

(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.

(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.

SUPPLEMENTARY INFORMATION:

Background

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.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2018-24-03, Amendment 39-19507 (83 FR
61523, November 30, 2018) (AD 2018-24-03). AD 2018-24-03 applied to all
Dassault Aviation Model Falcon 10 airplanes. The NPRM published in the
Federal Register on December 7, 2020 (85 FR 78808). The NPRM was
prompted by a determination that new or more restrictive airworthiness
limitations are necessary. The NPRM proposed to require revising the
existing maintenance or inspection program, as
applicable, to incorporate new or more restrictive airworthiness
limitations, as specified in EASA AD 2020-0215.
The FAA is issuing 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.

Comments

The FAA gave the public the opportunity to participate in
developing this final rule. The FAA received no comments on the NPRM or
on the determination of the cost to the public.

Conclusion

The FAA reviewed the relevant data and determined that air safety
and the public interest require adopting this final rule as proposed,
except for minor editorial changes. The FAA has determined that these
minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

Related Service Information 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 also requires 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.

Costs of Compliance

The FAA estimates that this AD affects 60 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
The FAA estimates the total cost per operator for the retained
actions from AD 2018-24-03 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

This AD will not have federalism implications under Executive Order
13132. This AD will 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 that this AD:
(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.
