SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 by adding an AD that would apply 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 SNPRM published in 
the Federal Register on June 21, 2017 (82 FR 28274) (``the SNPRM''). We 
preceded the SNPRM with a notice of proposed rulemaking that published 
in the Federal Register on November 25, 2016 (81 FR 85169) (``the 
NPRM''). The NPRM proposed to require an inspection of motorized cross-
feed fuel valves and, depending on findings, applicable corrective 
action(s). The NPRM was prompted by leakage of a motorized cross-feed 
fuel valve. The SNPRM proposed to require a reduced compliance time for 
the initial inspection, the addition of repetitive inspections and 
operational checks, and corrective actions if necessary. We are issuing 
this AD to detect and correct 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.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2017-0004, dated January 9, 2017 (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 task 28.007 
of the CN-235 Maintenance Review Board Report (MRB CN-235-PV01). 
Identical motorised fuel valves are installed on civilian CN-235 and 
C-295 aeroplanes, as cross-feed, shut-off and defueling valves.
    This condition, if not detected and corrected, could lead to 
failure of a motorised fuel valve and consequent improper 
functioning of the fuel system or, in case of an ignition source, 
could lead to a fire, possibly resulting in damage to the aeroplane 
and injury to occupants.
    To address this potentially unsafe condition, Airbus Defence & 
Space (D&S) issued Alert Operators Transmission (AOT)-CN235-28-0001 
and AOT-C295-28-0001 to provide inspection instructions.
    Consequently, EASA issued AD 2016-0071 to require a one-time 
inspection of the affected motorised fuel valves and, depending on 
findings, accomplishment of applicable corrective action(s).
    Since that [EASA] AD was issued, new occurrences of fuel leakage 
involving the

[[Page 44896]]

affected motorised fuel valves were reported and Airbus D&S issued 
Revision 1 of AOT-CN235-28-0001 and Revision 1 of AOT-C295-28-0001 
to introduce repetitive inspections and operational checks of the 
affected motorised fuel valves.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2016-0071, which is superseded, and 
introduces repetitive inspections and operational checks [and 
corrective actions, if necessary] of the affected fuel valves.

    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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the SNPRM or on the determination 
of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    Airbus Defense and Space has issued Alert Operators Transmission 
(AOT) AOT-C295-28-0001, Revision 1, dated September 27, 2016; and AOT-
CN235-28-0001, Revision 1, dated September 27, 2016. This service 
information describes procedures for repetitive inspections, 
replacement of the motorized fuel valves, and operational checks and 
corrective actions on affected motorized fuel valves. 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.

Costs of Compliance

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

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

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

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

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

    We have received no definitive data that will enable us to provide 
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 control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this 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 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

Regulatory Findings

    We determined that 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.

[[Page 44897]]

    For the reasons discussed above, I certify that this AD:
    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.
