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:
<bullet> Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
<bullet> 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:
[[Page 17501]]
Estimated Costs of On-Condition Actions *
----------------------------------------------------------------------------------------------------------------
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.
