Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Dassault Aviation Model Falcon 10 airplanes. This proposed AD 
was prompted by a report of hydraulic fluid on the ground near the main 
landing gear (MLG) brake assembly. The hydraulic leakage started in a 
cracked hydraulic pipe, with the crack likely due to chafing between 
two hydraulic pipes or between hydraulic pipes and structure. This 
proposed AD would require an inspection for chafing or interference of 
certain hydraulic pipes and certain rib passage holes, and, depending 
on findings, modification or repair, as specified in a European Union 
Aviation Safety Agency (EASA) AD, which will be incorporated 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 June 22, 
2020.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0072, dated March 26, 2020 
(``EASA AD 2020-0072'') (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 report of hydraulic fluid on the 
ground near the MLG brake assembly. The hydraulic leakage started in a 
cracked System #2 hydraulic pipe, with the crack likely due to chafing 
between two hydraulic pipes or between hydraulic pipes and structure. 
The FAA is proposing this AD to address chafed or cracked hydraulic 
pipes, which could lead to hydraulic fluid leakage near an ignition 
source and possibly result in an uncontained fire. See the MCAI for 
additional background information.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2020-0072 describes procedures for an inspection for 
chafing or interference of the System #2 hydraulic pipes and rib 1 to 
rib 2a passage holes, and, depending on findings, modification to 
prevent interference or chafing at rib passage holes or repair. 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 our bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD because the FAA 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop in other 
products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2020-0072 described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this 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 2020-0072 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2020-0072 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 2020-0072 that is required for compliance with EASA AD 2020-
0072 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2020-0448 after the FAA 
final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 85 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                  Labor cost                               Parts cost                 product        operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170............  None............................            $170         $14,450
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
            Labor cost                   Parts cost           product
------------------------------------------------------------------------
Up to 24 work-hours x $85 per hour  Up to $5,500........          $7,540
 = $2,040.
------------------------------------------------------------------------

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

[[Page 27172]]

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 has 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.

unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, European Union Aviation Safety Agency (EASA) AD 
2020-0072, dated March 26, 2020 (``EASA AD 2020-0072'').

(h) Exceptions to EASA AD 2020-0072

    (1) Where EASA AD 2020-0072 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2020-0072 does not apply 
to this AD.
