Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2018-0064, dated March 23, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Airbus SAS Model A330-200 Freighter, -200 and -300 series airplanes; and Airbus SAS Model A340-200, -300, -500, and -600 series airplanes. The MCAI states: Some events of depressurisation of hydraulic reservoirs have been reported, due to air leakage from the HR PRV [hydraulic reservoir pressure relief valve]. The results of the investigations revealed that the air leakage was due to the extrusion of the O-ring seal from the HR PRV. This may have [[Page 38089]] happened during HR maintenance, testing or during flight, if HR over-filling was performed, as a result of which hydraulic fluid could pass through the PRV, causing [the] PRV seal to migrate from its nominal position, leading to loss of HR pressurisation. This condition, if not detected and corrected, could lead to the loss of one or more hydraulic systems, possibly resulting in loss of control of the aeroplane. To address this potential unsafe condition, Airbus issued the AOT [Alert Operators Transmission (AOT) A29L005-16, dated January 28, 2016] to provide instructions to inspect the HR fluid level of each hydraulic circuit and to provide instructions for certain actions when servicing with hydraulic fluid is accomplished on an HR. Consequently, EASA published AD 2016-0107 [related FAA AD 2017- 01-08, Amendment 39-18775 (82 FR 1593, January 6, 2017) (``2017-01- 08'')] to require accomplishment of these actions for aeroplanes in service. Since that [EASA] AD was issued, it was determined that the detected air leakage was due to the extrusion of the O-ring seal from a specific batch of HR PRV. Airbus published the applicable inspection SB [service bulletin] to inspect the HR of each hydraulic circuit and to provide instructions to identify the affected parts, and the Modification SB to provide instructions for replacement of each affected part fitted on an affected HR. For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2016-0107, which is superseded, and requires the [identification and] replacement [and re-identification] of the affected parts. 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-2018- 0704. Relationship Between Proposed AD and AD 2017-01-08 This NPRM does not propose to supersede AD 2017-01-08. Rather, we have determined that a stand-alone AD is more appropriate to address the changes in the MCAI. This proposed AD would require identifying, replacing, and re-identifying affected HR PRVs. Accomplishing the proposed actions would then terminate all requirements of AD 2017-01- 08. Related Service Information Under 1 CFR Part 51 Airbus SAS has issued the following service information, which describes procedures for identifying HR part numbers. These documents are distinct since they apply to different airplane models. Service Bulletin A330-29-3134, dated August 16, 2017. Service Bulletin A340-29-4102, dated August 16, 2017. Airbus SAS has also issued the following service information, which describes procedures for replacing and re-identifying affected PRVs and HRs. These documents are distinct since they apply to different airplane models. Service Bulletin A330-29-3131, dated August 11, 2017. Service Bulletin A330-29-3132, dated August 11, 2017. Service Bulletin A330-29-3133, dated August 11, 2017. Service Bulletin A340-29-4099, dated August 11. 2017. Service Bulletin A340-29-4100, dated August 11, 2017. Service Bulletin A340-29-4101, dated August 11, 2017. Service Bulletin A340-29-5026, dated August 11, 2017. Safran has issued Vendor Service Bulletins 42-29-005, Revision 01, dated September 26, 2017, and 42-29-006, Revision 01, dated September 27, 2017. These documents are distinct since they apply to different airplane models. This service information describes procedures for replacing affected HR PRVs, and including the serial numbers of those PRVs. 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. FAA's Determination This 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 proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed Requirements of This NPRM This proposed AD would require accomplishing the actions specified in the service information described previously. Costs of Compliance We estimate that this proposed AD affects 103 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Up to 6 work-hours x $85 per hour = Up to $510.................. $3,390 Up to $3,900 Up to $401,700 ---------------------------------------------------------------------------------------------------------------- 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 proposed 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national [[Page 38090]] Government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify this proposed regulation: 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2.
