    SUPPLEMENTARY INFORMATION:

    Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus SAS Model A318 series; Model A319 series; Model A320 series; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. The NPRM published in the Federal Register on June 20, 2018 (83 FR 28555). The NPRM was prompted by reports of multiple AoA probe blockages. The NPRM proposed to require all ELAC units to be upgraded with new software, or replaced with upgraded units.

    We are issuing this AD to address the blockage of AoA probes. This condition, if not corrected, could lead to undue activation of the AoA protection, reverting to manual control of the airplane, which, under specific circumstances, could result in reduced control of the airplane.

    The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018-0007R1, dated January 19, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Airbus SAS Model A318 series; Model A319 series; Model A320 series; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. The MCAI states:

    Occurrences were reported on multiple Angle of Attack (AoA) probes blockages. Investigation results indicated the need for improved AoA monitoring in order to detect cases of AoA probe blockage.

    This condition, if not corrected, could lead to undue activation of the AoA protection, reverting to manual control of the aeroplane, which, under specific circumstances, could result in reduced control of the aeroplane.

    To address this potential unsafe condition, Airbus developed several Elevator Aileron Computer (ELAC) standards, i.e. ELAC units loaded with a specific software Part Number (P/N), and EASA issued AD 2017-0008, retaining part of the requirements of EASA AD 2015-0088R1 [which corresponds to FAA AD 2016-17-03, Amendment 39-18616 (81 FR 55358, August 19, 2016) (“AD 2016-17-03”)], which was superseded, and requiring an upgrade of all ELAC units with ELAC L99 standard, which introduces improvements in the AoA probe monitoring for Current Engine Option (CEO) aeroplanes, and also incorporates flight control aspects for New Engine Option (NEO) aeroplanes.

    Since that [EASA] AD was issued, it was determined that clarification is necessary for the Parts Installation requirements, and some typographical (P/N) errors were detected. This [EASA] AD is revised accordingly.

    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-2018-0556.

    Comments

    We 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. United Airlines had no objection to the NPRM.

    Request To Reduce the Compliance Time for Model A320 Airplanes

    Air Line Pilots Association, International (ALPA), requested that the compliance time for the Model A320 series airplanes be reduced from 36 to 24 months, the same as for the other models. ALPA contended that 36 months is not an appropriate compliance time for the A320 because the severity of risk for the A320 is not less than for the other models.

    We disagree with the request to reduce the compliance time for Model A320 series airplanes. We concur with the compliance time established by EASA, the state of design authority, which is based on the overall risk to the fleet, including the severity of the failure and the likelihood of the failure's occurrence. In conjunction with the manufacturer, we have determined that the compliance time for each airplane model will accommodate the time necessary to ensure the availability of required parts and maintain an adequate level of safety. However, if additional data are presented that would justify a shorter compliance time, we may consider further rulemaking on this issue. We have not changed this AD regarding this request.

    Request To Modify Paragraphs (h)(3) and (j)(2)(iii) of the Proposed AD

    Airbus SAS requested that we modify paragraphs (h)(3) and (j)(2)(iii) of the proposed AD to read: “The data-loadable ELAC unit is checked by two different means: by the line replaceable unit (LRU) identification and either the label call up or the Alpha Call Up ELA 1 and ELA 2 (if available).” We infer that this change was requested to clarify the meaning of those paragraphs.

    We agree to clarify the specified paragraphs. We have changed paragraphs (h)(3) and (j)(2)(iii) of this AD accordingly.

    Request To Clarify Paragraph (h)(3) of the Proposed AD

    Delta Air Lines (DAL) asked whether paragraph (h)(3) of the proposed AD, as written, actually requires two separate methods of identification for the same unit. DAL explained that not all ELAC units are labeled with the software load, that the labels were added later by Thales, and that there is no guarantee they will be present on the LRU.

    We agree to clarify that there are two methods of checking the data-loadable ELAC unit. As stated previously, we have revised paragraph (h)(3) of this AD and paragraph (j)(2)(iii) of this AD to make this more clear.Start Printed Page 4688

    Request To Clarify Paragraphs (h) and (j)(2) of the Proposed AD

    Alaska Airlines asked whether the four conditions given in paragraphs (h)(1) through (h)(4) and (j)(2)(i) through (j)(2)(iv) of the proposed AD apply only to the “modification instructions approved by an EASA Design Organization Approval (DOA) (other than Airbus SAS's EASA DOA),” or also to the modification instructions approved by other authorities, as mentioned earlier in the paragraph.

    We agree to clarify this aspect of the specified paragraphs. We have revised the language regarding the applicability of the four conditions given in paragraphs (h)(1) through (h)(4) and (j)(2)(i) through (j)(2)(iv) of this AD to clarify that these paragraphs are applicable only to the modification instructions that are part of an FAA-accepted maintenance or inspection program, as applicable. We have revised the language in paragraphs (h) and (j)(2) of this AD accordingly.

    Request To Address Onboard Data Loading of ELAC Units

    Alaska Airlines requested that we modify paragraph (j) of the proposed AD to address onboard loading of ELAC units with later software. Alaska Airlines also requested that we revise paragraphs (j)(2) and (j)(4) of the proposed AD to specify that those paragraphs are not applicable to onboard data loading, since they refer to removing and re-installing the data-loadable ELAC units. We infer that Alaska Airlines wants us to revise paragraphs (j)(2)(ii) and (j)(2)(iv) of the proposed AD because those paragraphs refer to the removal and re-installation of the data-loadable ELAC units.

    We agree. We have modified paragraph (j) of this AD to include onboard loading of ELAC software and revised paragraphs (j)(2)(ii) and (j)(2)(iv) of this AD as requested.

    Request To Remove DOA Signature Requirement

    DAL requested that the DOA signature requirement be removed from the proposed AD and that the previously established statement “The technical content of this document is approved under the authority of Design Organization Approval No. EASA 21J.031” used by the DOA in Airbus SAS service bulletins be deemed sufficient. DAL observed that if this document requires a signature, it is deviating from the previously established standard and will generate unnecessary alternative method of compliance (AMOC) requests from the administrator and/or unnecessary revisions of service bulletins by the manufacturer. DAL also stated that requiring a signature does not enhance or affect the safety of the aircraft.

    We disagree with DAL's request to remove the DOA signature requirement. The FAA specifies the DOA signature requirement in the “contacting the manufacturer” paragraph (such as paragraph (m)(2) of this AD) because in the past some U.S. operators misinterpreted that any document, including an email message, received from a manufacturer or the manufacturer's customer support organization was considered DOA approved. Under the EASA DOA system, the only documents officially recognized as EASA-approved are those accompanied by the DOA-authorized signature. For the purpose of compliance with the “contacting the manufacturer” paragraph in FAA ADs, the FAA can only recognize the documents approved by the FAA, or EASA, or those authorized to make an EASA approval under the DOA system.

    We also disagree with the request to use the statement “The technical content of this document is approved under the authority of Design Organization Approval No. EASA 21J.031.” This statement only recognizes that the service bulletin was originally approved under the authority of the DOA system as approved by EASA, and does not provide any process for an operator to receive other approved instructions from either EASA or the authorized DOA as a means of compliance to the FAA AD. The current “contacting the manufacturer” paragraph and the requirement for the DOA-authorized signature actually results in fewer AMOCs because of the FAA's recognition of both EASA and specific EASA DOA approvals under the “contacting the manufacturer” paragraph in this and other FAA ADs. We have not changed this AD in this regard.

    Request To Clarify Paragraph (h)(1) of the Proposed AD

    DAL questioned the purpose of the condition stated in paragraph (h)(1) of the proposed AD, i.e., that there should be no warning or maintenance message before the ELAC unit is removed. DAL stated that if an electronic centralized aircraft monitor (ECAM) has a maintenance message or ECAM warning that is not airworthy, as a standard procedure the aircraft will be repaired and put back in an airworthy condition prior to return to service.

    We agree that clarification is necessary. The intent of the condition stated in paragraph (h)(1) of this AD is to ensure that all pre-existing conditions have been fixed before uploading new software to an ELAC unit or installing a unit with updated software. We have not changed this AD regarding this question.

    Request To Clarify Whether Certain Steps Are Required for Compliance

    DAL questioned whether all of the steps in Airbus SAS Aircraft Maintenance Manual (AMM) Tasks 27-93-34-000-001-A and 27-93-34-400-001-A, such as accessing the access doors using an adjustable platform, are required for compliance.

    We agree to clarify. The conditions in paragraphs (h)(2), (h)(4), (j)(2)(ii), and (j)(2)(iv) of this AD specified that actions must be done as specified in the AMM tasks. We did not intend the accessing and closing instructions of the AMM tasks to be required for compliance. We have revised paragraphs (h)(2), (h)(4), (j)(2)(ii), and (j)(2)(iv) of this AD accordingly.

    Conclusion

    We 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. We have determined that these minor changes:

    • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
    • Do not add any additional burden upon the public than was already proposed in the NPRM.

    We also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule.

    Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-27-1263, dated April 28, 2017; and Service Bulletin A320-27-1264, dated April 28, 2017. The service information describes the software upgrade or replacement of ELAC units. These documents are distinct because they apply to different airplane configurations.

    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.

    Costs of Compliance

    We estimate that this AD affects 1,250 airplanes of U.S. registry.Start Printed Page 4689

    We estimate the following costs to comply with this AD:

    Estimated Costs

    ActionLabor costParts costCost per productCost on U.S. operators
    ModificationUp to 3 work-hours × $85 per hour = $255Up to $7,970Up to $8,225Up to $10,281,250.

    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 and associated appliances to the Director of the System Oversight Division.

    Regulatory Findings

    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.

    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.
