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: We propose to adopt a new airworthiness directive (AD) 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. This proposed AD was 
prompted by leakage of a motorized cross-feed fuel valve. This proposed 
AD would require an inspection of the affected fuel valves and, 
depending on findings, applicable corrective action(s). We are 
proposing this AD to detect and correct leaks in a motorized cross-feed 
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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued 
Airworthiness Directive 2016-0071, dated April 11, 2016 (referred to 
after this 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 MCAI states:

    Leakage of a motorised cross-feed fuel valve Part Number (P/N) 
7923227F was reported on a CN-235-100M aeroplane. The leakage was 
observed through the valve electrical connectors and detected during 
accomplishment of a functional check in accordance with the CN-235 
aeroplane Maintenance Review Board Report (MRB-PV01M), task 28.007. 
Identical motorised fuel valves are installed on CN-235 and C-295 
aeroplanes, corresponding to civil type design, as cross-feed, shut-
off and defueling valves, as applicable to aeroplane model and 
configuration.
    This condition, if not detected and corrected, could lead to 
failure of a motorised fuel valve and consequent improper fuel 
system functioning or, in case of the presence of an ignition 
source, possibly resulting in an aeroplane fire.
    To address this potentially unsafe condition, Airbus Defense & 
Space (D&S) issued Alert Operators Transmission (AOT)-CN235-28-0001 
and AOT-C295-28-0001 to provide inspection instructions.
    For the reasons described above, this [EASA] AD requires an 
inspection of the affected motorised fuel valves and, depending on 
findings, accomplishment of applicable corrective action(s) [(valve 
replacement)].

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9386.

Related Service Information Under 1 CFR Part 51

    Airbus Defense and Space S.A. has issued AOT-CN235-28-0001, dated 
February 19, 2016; and AOT-C295-28-0001, dated February 19, 2016. The 
service information describes procedures for inspecting and replacing 
the motorized fuel valves. The service information also describes 
procedures for reporting inspection findings. These documents are 
distinct since they apply to different airplane models. This service 
information 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, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this

[[Page 85170]]

AD because we evaluated all pertinent information and determined an 
unsafe condition exists and is likely to exist or develop on other 
products of these same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 14 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

                                      = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of airplanes that might need 
these replacements:

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 the FAA at 800 Independence Ave. SW., Washington, DC 
20591, ATTN: Information Collection Clearance Officer, AES-200.

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.
    We are 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

    We 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. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
