AD 2021-06-08

The FAA is superseding Airworthiness Directive (AD) 2017-19- 25, which 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. AD 2017-19-25 required repetitive inspections and operational checks of the affected fuel valves, and corrective actions if necessary. This AD continues to require repetitive inspections and operational checks of the affected fuel valves, and corrective actions if necessary, and also limits the installation of affected parts to those that are maintained in accordance with certain instructions, as specified in a European Union Aviation Safety Agency (EASA), which is incorporated by reference. This AD was prompted by 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 issuing this AD to address the unsafe condition on these products.

Final rule.

Background \n\n\n\tThe 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. \n\tThe 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 ofaffected 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. \n\tThe 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. \n\nComments \n\n\n\tThe 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. \n\nConclusion \n\n\n\tThe 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: \n\tAre consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and \n\tDo not add any additional burden upon the public than was already proposed in the NPRM. \n\nRelated Service Information Under 1 CFR Part 51 \n\n\n\tEASA 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. \n\tThis 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 \n\n\n\tThe FAA estimates that this AD affects 8 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: \n\n\n\tEstimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- \n\tCost per Cost on U.S. \n\tLabor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- 3 work-hours x $85 per hour = $255........................... $0 $255 $2,040 ---------------------------------------------------------------------------------------------------------------- \n\n\n\tThe 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 thesereplacements: \n\n((Page 17501)) \n\n\n\n\n\n\n\tEstimated Costs of On-Condition Actions * ---------------------------------------------------------------------------------------------------------------- \n\tCost per Cost on U.S. \n\tLabor cost Parts cost product operators ------------------------------------------------------------------------------------------------- ----------------- 5 work-hours x $85 per hour = $425............................. $38,448 $38,873 ---------------------------------------------------------------------------------------------------------------- \n* Table does not include estimated costs for reporting.\n\n\n\n\tThe 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. \n\tThe 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. \n\nPaperwork Reduction Act \n\n\n\tA 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. \n\nAuthority for This Rulemaking \n\n\n\tTitle 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. \n\tThe 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. \n\nRegulatory Findings \n\n\n\tThis 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. \n\tFor the reasons discussed above, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under Executive Order 12866, \n\t(2) Will not affect intrastate aviation in Alaska, and \n\t(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. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
