RIN 2120-AA64


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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2017-19-25, which applies 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 requires repetitive inspections and 
operational checks of the affected fuel valves, and corrective actions 
if necessary. Since the FAA issued AD 2017-19-25, it has been 
determined 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. This proposed AD would continue 
to require repetitive inspections and operational checks of the 
affected fuel valves, and corrective actions if necessary. This 
proposed AD would also limit the installation of affected parts to 
those that that are maintained in accordance with certain instructions, 
as specified in a European Union Aviation Safety Agency (EASA), 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 February 1, 
2021.

Discussion

    The FAA issued AD 2017-19-25, Amendment 39-19055 (82 FR 44895, 
September 27, 2017) (AD 2017-19-25), which applies 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 requires 
repetitive inspections and operational checks of the affected fuel 
valves, and corrective actions if necessary. The FAA issued AD 2017-19-
25 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.

Actions Since AD 2017-19-25 Was Issued

    Since the FAA issued AD 2017-19-25, it has been determined 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 EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0212, dated August 27, 2019

[[Page 81852]]

(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. EASA AD 2019-
0212 supersedes EASA AD 2017-0004 (which corresponds to FAA AD 2017-19-
25).
    This proposed AD 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 
FAA is proposing 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.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2017-19-25, this proposed AD would retain all of the 
requirements of AD 2017-19-25. Those requirements are referenced in 
EASA AD 2019-0212, which, in turn, is referenced in paragraph (g) of 
this proposed AD.

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.

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 the FAA's 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 pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2019-0212 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 2019-0212 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2019-0212 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 2019-0212 that is required for compliance with EASA AD 2019-
0212 will be available on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2020-1134 after the FAA 
final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 8 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
----------------------------------------------------------------------------------------------------------------
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 
proposed inspection. The FAA has no way of determining the number of 
aircraft that might need these replacements:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
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 proposed on-condition reporting requirement in this 
proposed 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 proposed 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 control 
number for the collection of information required by this proposed AD 
is 2120-0056. The paperwork cost associated with this proposed AD has 
been detailed in the Costs of Compliance section of this document and 
includes time for reviewing instructions, as well as completing and 
reviewing the collection of information. Therefore, all reporting 
associated with this proposed AD is mandatory. Comments concerning the 
accuracy of this burden and suggestions for reducing the burden should 
be directed 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

    The FAA 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.
