ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2019-23-
05, which applied to all Dassault Aviation Model MYSTERE-FALCON 900 
airplanes. AD 2019-23-05 required revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. This AD continues to require 
revising the existing maintenance or inspection program, as applicable, 
to incorporate those new or more restrictive airworthiness limitations, 
and also requires revising the existing maintenance or inspection 
program, as applicable, to incorporate additional new or more 
restrictive airworthiness limitations; as specified in a European Union 
Aviation Safety Agency (EASA) AD, which is incorporated by reference. 
This AD was prompted by a determination that new or more restrictive 
airworthiness limitations are necessary. The FAA is issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective January 25, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 25, 
2021.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0115, dated May 20, 2020 (EASA 
AD 2020-0115) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Dassault Aviation Model MYSTERE-FALCON 900 airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2019-23-05, Amendment 39-19799 (84 FR 
67169, December 9, 2019) (AD 2019-23-05). AD 2019-23-05 applied to all 
Dassault Aviation Model MYSTERE-FALCON 900 airplanes. The NPRM 
published in the Federal Register on August 19, 2020 (85 FR 50970). The 
NPRM was prompted by a determination that new or more restrictive 
airworthiness limitations are necessary. The NPRM proposed to continue 
to require revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive airworthiness 
limitations. The NPRM also proposed to require revising the existing 
maintenance or inspection program, as applicable, to incorporate 
additional new or more restrictive airworthiness limitations, as 
specified in a EASA AD.
    The FAA is issuing this AD to address 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 has considered the comments 
received.

Support for the NPRM

    Ian Reineck indicated support for the NPRM.

Request To Include Actions in the Cost Estimate

    Ian Reineck requested that the cost estimate be revised to include 
structural upkeep per flight hours, rather than solely maintenance work 
hours. The commenter stated this is what determines the core functions 
inside aviation maintenance schedules. The commenter also stated this 
would be inclusive, regardless of operator, but still reflect the cost 
of an average operator's inspection through the quantity of accumulated 
flight time on the airplane. The commenter concluded that, if flight 
time is not presented in the inspection cost, it presents another 
problem: These aircraft may change ownership or operator-ship as they 
age.
    The FAA infers that the commenter is requesting that the FAA 
include the costs in this AD for complying with the actions (e.g., 
inspections) that are specified in the airworthiness limitations 
document referenced in EASA AD 2020-0115. The FAA disagrees because 
those actions are not directly required by this AD. Additionally, the 
FAA does not distribute the costs over time because the cost estimates 
have been

[[Page 82902]]

standardized to include the larger whole cost of the requirement, not 
the more uniform cost per flight hour, which the FAA has determined is 
best to inform the broadest user base. The cost information provided in 
this AD describes only the direct costs of the specific actions 
required by this AD. This AD requires only 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 2020-0115, and provides a 
compliance time to phase in the initial actions. Section 91.403(c) of 
the Federal Aviation Regulations (14 CFR 91.403(c)) requires the 
actions once the maintenance or inspection program is changed. 
Therefore, we have not changed this final rule in this regard.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, 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 2020-0115 describes new or more restrictive airworthiness 
limitations for airplane structures and safe life limits.
    This AD also requires Chapter 5-40, Airworthiness Limitations, 
Revision 24, dated September 2018, of the Dassault Aviation Falcon 900 
Maintenance Manual, which the Director of the Federal Register approved 
for incorporation by reference as of January 13, 2020 (84 FR 67169, 
December 9, 2019).
    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 105 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 2019-23-05 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 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.
