AD 2017-25-16 SUPERSEDED

We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200, A330-200 \n\n((Page 58719)) \n\nFreighter, and A330-300 series airplanes; and Airbus Model A340-200, A340-300, A340-500, and A340-600 series airplanes. This AD requires repetitive inspections of certain fuel pumps for cavitation erosion, corrective action if necessary, and revision of the minimum equipment list (MEL). This AD was prompted by a report indicating that a fuel pump showing cavitation erosion breached the fuel pump housing and exposed the fuel pump power supply wires. We are issuing this AD to address the unsafe condition on these products.

Final rule; request for comments.

Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1.

Discussion \n\n\n\tThe European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017-0224, dated November 10, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ''the MCAI''), to correct an unsafe condition for all Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes; and Airbus Model A340-200, A340-300, A340-500, and A340-600 series airplanes. The MCAI states: \n\n\n\tAn occurrence was reported of a fuel pump showing cavitation erosion which breached the fuel pump housing through the inlet webs and exposed the fuel pump power supply wires. Inspections accomplished on fuel pumps removed from other aeroplanes identified signs of erosion in varying degrees. However, no other instance of break-through due to cavitation erosion was found. A list of potentially affected fuel pump Part Numbers (P/N) was established. \n\tThis condition, if not detected and corrected, could result, in case the pump is running dry, in an ignition source in the fuel tank, which may result in a fuel tank explosion and consequent loss of the aeroplane. \n\tTo address this potential unsafe condition, Airbus issued Alert Operators Transmission (AOT) A28L006-17 to provide instructions to inspect some fuel pumps when installed at specific positions, and to update the applicable Master Minimum Equipment List (MMEL). \n\tFor the reasons described above, this (EASA) AD requires repetitive inspections of these fuel pumps and, depending on findings, replacement of damaged fuel pumps with serviceable parts. This (EASA) AD also requires an update of the applicable MMEL, and the reporting of inspection results to Airbus. \n\tThis (EASA) AD is considered to be an interim measure and further (EASA) AD action may follow. \n\nAlthough the MCAI requires updating the ''master minimum equipment list (MMEL),'' this AD requires revising the''minimum equipment list (MEL).'' The MMEL is a master list of the minimum equipment that the airplane can operate with under given circumstances. A MEL is derived from the MMEL and is tailored for individual operators. You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-1104. \n\nRelated Service Information Under 1 CFR Part 51 \n\n\n\tAirbus has issued Alert Operators Transmission A28L006-17, Rev. 00, dated November 3, 2017. The service information describes procedures for inspection of certain fuel pumps for cavitation erosion, and corrective actions. The service information also describes dispatch restrictions that affect the MEL. 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. \n\nFAA's Determination and Requirements of This AD \n\n\n\tThis 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 issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of these same type designs. \n\nFAA's Determination of the Effective Date \n\n\n\tAn unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because the unsafe condition could result in an ignition source in the fuel tank, which could result in a fuel tank explosion. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days. \n\nComments Invited \n\n\n\tThis AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant \n\n((Page 58720)) \n\ndata, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ''Docket No. FAA- 2017-1104; Product Identifier 2017-NM-153-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD based on those comments. \n\tWe will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. \n\nCosts of Compliance \n\n\n\tWe estimate that this AD affects 107 airplanes of U.S. registry. We estimate the following costs to comply with this AD: \n\n\n\tEstimated Costs ---------------------------------------------------------------------------------------------------------------- \n\tCost on U.S. \n\tAction Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspection................. 4 work-hours x $85 per $0 $340 per inspection $36,380 per \n\thour = $340 per cycle. inspection cycle. \n\tinspection cycle. Reporting.................. 1 work-hour x $85 per 0 $85 per inspection $9,095 per \n\thour = $85 per cycle. inspection cycle. \n\tinspection cycle. MEL revision............... 1 work-hour x $85 per 0 $85................ $9,095. \n\thour = $85. ---------------------------------------------------------------------------------------------------------------- \n\n\n\tWe estimate the following costs to do any necessary replacements that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these replacements: \n\n\n\tOn-Condition Costs ---------------------------------------------------------------------------------------------------------------- \n\tCost per \n\tAction Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replacement................................ 2 work-hours x $85 per hour = $170. $8,000 $8,170 ---------------------------------------------------------------------------------------------------------------- \n\nPaperwork Reduction Act \n\n\n\tA federal agency may not conduct orsponsor, 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. \n\nAuthority for This Rulemaking \n\n\n\tTitle 49 of the United States Code specifies the FAA's authorityto 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\tWe 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. \n\tThis 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 theCompliance 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. \n\nRegulatory Findings \n\n\n\tWe 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. \n\tFor the reasons discussed above, I certify that this AD: \n\t1. Is not a ''significant regulatory action'' under Executive Order 12866; \n\t2. Is not a ''significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); \n\t3. Will not affect intrastate aviation in Alaska; and \n\t4. 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.
