Airworthiness Directives; Airbus Defense and Space S.A. (Formerly 
Known as Construcciones Aeronauticas, S.A.) Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2017-19-
25, which applied to all Airbus Defense and Space S.A. Model CN-235, 
CN-235-100, CN-235-200, and CN-235-300 airplanes; and Model C-295 
airplanes. AD 2017-19-25 required repetitive inspections and 
operational

[[Page 17500]]

checks of the affected fuel valves, and corrective actions if 
necessary. This AD continues to require repetitive inspections and 
operational checks of the affected fuel valves, and corrective actions 
if necessary, and also limits the installation of affected parts to 
those that are maintained in accordance with certain instructions, as 
specified in a European Union Aviation Safety Agency (EASA), which is 
incorporated by reference. This AD was prompted by a determination that 
it is necessary to limit the installation of affected parts specified 
in AD 2017-19-25 to those parts that are maintained in accordance with 
certain instructions. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective May 10, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 10, 
2021.

SUPPLEMENTARY INFORMATION:

Background

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0212, dated August 27, 2019 
(EASA AD 2019-0212) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-
200, and CN-235-300 airplanes; and Model C-295 airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2017-19-25, Amendment 39-19055 (82 FR 
44895, September 27, 2017) (AD 2017-19-25). AD 2017-19-25 applied to 
all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, 
and CN-235-300 airplanes; and Model C-295 airplanes. The NPRM published 
in the Federal Register on December 17, 2020 (85 FR 81851). The NPRM 
was prompted by leakage of a motorized cross-feed fuel valve and a 
determination that it is necessary to limit the installation of 
affected parts specified in AD 2017-19-25 to those parts that are 
maintained in accordance with certain instructions. The NPRM proposed 
to continue to require repetitive inspections and operational checks of 
the affected fuel valves, and corrective actions if necessary, as 
specified in EASA AD 2019-0212. The NPRM also proposed to limit the 
installation of affected parts to those that are maintained in 
accordance with certain instructions, as specified in EASA AD 2019-
0212.
    The FAA is issuing this AD to address leaks in a motorized fuel 
valve, which could lead to failure of the fuel valve and consequent 
improper fuel system functioning or, in case of the presence of an 
ignition source, an airplane fire. 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 2019-0212 describes procedures for repetitive inspections 
and operational checks of the affected fuel valves (cycling procedures 
and reapplication of grease or overhaul as applicable), and corrective 
actions if necessary. Corrective actions include replacement. EASA AD 
2019-0212 also describes procedures for reporting inspection results.
    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 8 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255...........................              $0             $255           $2,040
----------------------------------------------------------------------------------------------------------------

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

                                                                                      Cost per       Cost on U.S.
                           Labor cost                               Parts cost        product         operators
------------------------------------------------------------------------------------------------- -----------------
5 work-hours x $85 per hour = $425.............................         $38,448          $38,873
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting.

    The FAA estimates that it would take about 1 work-hour per product 
to comply with the on-condition reporting requirement in this AD. The 
average labor rate is $85 per hour. Based on these figures, the FAA 
estimates the cost of reporting the inspection results on U.S. 
operators to be $85 per product.
    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition corrective actions for the operational 
check specified in this AD.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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.
