AD 2020-21-05

The FAA is superseding Airworthiness Directive (AD) 2017-25- 16, which applied to all Airbus SAS Model A330-200 Freighter, A330-200, A330-300, A340-200, A340-300, A340-500, and A340-600 series airplanes. AD 2017-25-16 required repetitive inspections of certain fuel pumps for cavitation erosion, corrective action if necessary, and revision of the minimum equipment list (MEL). This AD continues to require those actions, and also requires expanding the inspection area, adding certain maintenance actions, and expanding the applicability, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by reports of a fuel pump showing cavitation erosion that exposed the fuel pump power supply wires, and by new findings that suggest the need to expand the inspection area and the applicability. The FAA is issuing this AD to address the unsafe condition on these products.

Final rule.

Discussion \n\n\n\tThe EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0291R1, dated March 4, 2020 (''EASA AD 2019-0291R1'') (also referred to as the Mandatory Continuing Airworthiness Information, or ''the MCAI''), to correct an unsafe condition for all Airbus SAS Model A330-200 Freighter, A330-200, A330- 300, A330-900, A340-200, and A340-300 series airplanes; and Model A340- 541, -542, -642, and -643 airplanes. EASA AD 2019-0291R1 supersedes EASA AD 2017-0224, dated November 10, 2017 (which corresponds to FAA AD 2017-25-16, Amendment 39-19130 (82 FR 58718, December 14, 2017) (''AD 2017-25-16'')). Model A340-542 and -643 airplanes are not certified by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability. \n\tThe FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2017-25-16. AD 2017-25-16 applied to 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 NPRM published in the Federal Register on March 9, 2020 (85 FR 13578). The NPRM was prompted by reports of a fuel pump showing cavitation erosion that exposed the fuel pump power supply wires, and by new findings that suggest the need to expand \n\n((Page 64964)) \n\nthe inspection area and the applicability. The NPRM proposed to continue to require repetitive inspections of certain fuel pumps for cavitation erosion, corrective action if necessary, and revision of the MEL, as specified in an EASA AD. The NPRM also proposed to require expanding the inspection area, adding certain maintenance actions, and expanding the applicability, as specified in an EASA AD. \n\tThe FAA is issuing this AD to address fuel pump erosion caused by cavitation. If this condition is not addressed, a pump running dry could resultin a fuel tank explosion and consequent loss of the airplane. 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 following presents the comments received on the NPRM and the FAA's response to each comment. \n\nSupport for the NPRM \n\n\n\tThe Air Line Pilots Association, International (ALPA) expressed support for the proposed AD. \n\nRequest To Require Revised EASA AD \n\n\n\tDelta Air Lines (DAL) requested that the FAA revise paragraph (g) of the proposed AD to require compliance with EASA AD 2019-0291R1, dated March 4, 2020, rather than EASA AD 2019-0291, dated November 29, 2019. DAL observed that while the NPRM was being prepared, EASA published the revised AD. \n\tThe FAA agrees with the commenter's request. Since the NPRM was issued, EASA issued EASA AD 2019-0291R1, which corrects and clarifies some aspects, particularly repair (not overhaul) of affected parts using the instructions of Eaton Aerospace CMM 28-21-55 (housing replaced). The FAA has determined that no additional work is required for airplanes that have accomplished the actions specified in EASA AD 2019-0291. Therefore, the FAA has revised this final rule to specify EASA AD 2019-0291R1. \n\nConclusion \n\n\n\tThe FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the changes described previously and 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\tThe FAA also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule. \n\nRelated IBR Material Under 1 CFR Part 51 \n\n\n\tEASA AD 2019-0291R1 describes procedures for repetitive inspections of all affected parts, replacement if necessary, updating the applicable Master Minimum Equipment List (MMEL), and certain maintenance actions related to defueling and ground fuel transfer operations This 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. \n\nInterim Action \n\n\n\tThe FAA considers this AD interim action. The manufacturer is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, the FAA might consider additional rulemaking. \n\nCosts of Compliance \n\n\n\tThe FAA estimates that this AD affects 107 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\tAction Labor cost Parts cost Cost per product Cost on U.S. operators ---------------------------------------------------------------------------------------------------------------- Retained actions from AD 2017- Up to 4 work- $0 Up to $340....... Up to $36,380. \n\t25-16. hours x $85 per \n\thour = Up to \n\t$340. New actions.................... Up to 68 work- 0 Up to $5,780..... Up to $618,460. \n\thours x $85 per \n\thour = Up to \n\t$5,780. MEL revision................... 1 workhour x $85 0 $85.............. $9,095. \n\t= $85. ---------------------------------------------------------------------------------------------------------------- \n\n\n\tThe FAA estimates the following costs to do any necessary on- condition action that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need this on-condition action: \n\n\n\tEstimated Costs of On-Condition Actions ------------------------------------------------------------------------ \n\tLabor cost Parts cost Cost per product ------------------------------------------------------------------------ Up to 126 work-hours x $85 Up to $173,680.. Up to $184,390. \n\tper hour = Up to $10,710. ------------------------------------------------------------------------ \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\n((Page 64965)) \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 entitiesunder 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.
