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 
                        ( print 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

 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.
                    ( print 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.
