AD 2020-07-18

The FAA is superseding Airworthiness Directive (AD) 2017-05- 12, which applied to certain Airbus SAS Model A318-112 airplanes; Model A319-111, -112, -115, -132, and -133 airplanes; Model A320-214, -232, and -233 airplanes; and Model A321-211, -212, -213, -231, and -232 airplanes. AD 2017-05-12 required a one-time eddy current conductivity measurement of certain cabin, cargo compartment, and frame structural parts to determine if aluminum alloy with inadequate heat treatment was used, and replacement if necessary. This AD retains the requirements of AD 2017-05-12, and for certain airplanes, requires additional work, as specified in a European Union \n\n((Page 21760)) \n\nAviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a determination that aluminum alloy with inadequate heat treatment had been used for additional structural parts. The FAA is issuing this AD to address the unsafe condition on these products.

Final rule.

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. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2.

Discussion \n\n\n\tThe EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0196, dated August 14, 2019 (''EASA AD 2019-0196'') (also referred to as the Mandatory Continuing Airworthiness Information, or ''the MCAI''), to correct an unsafe condition for certain Airbus SAS Model A318-112 airplanes; Model A319- 111, -112, -115, -132, and -133 airplanes; Model A320-214, -216, -232, and -233 airplanes; and Model A321-211, -212, -213, -231, and -232 airplanes. \n\tThe FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2017-05-12, Amendment 39-18823 (82 FR 13382, March 13, 2017) (''AD 2017-05-12''), which applied to certain Airbus SAS Model A318-112 airplanes; Model A319-111, -112, -115, -132, and -133 airplanes; Model A320-214, -232, and -233 airplanes; and Model A321-211, -212, -213, -231, and -232 airplanes. The NPRM published in the Federal Register on December 16, 2019(84 FR 68376). The NPRM was prompted by a determination that aluminum alloy with inadequate heat treatment had been used for additional structural parts. The NPRM proposed to retain the requirements of AD 2017-05-12, and for certain airplanes, would require additional work. The FAA is issuing this AD to address structural parts made of aluminum alloy with inadequate heat treatment, which could result in reduced structural integrity of the airplane. \n\nComments \n\n\n\tThe FAA gave the public the opportunity to participate in developing this final rule. The following presents the comment received on the NPRM and the FAA's response. \n\nRequest To Extend Compliance Time \n\n\n\tAmerican Airlines (AAL) asked that the FAA extend the compliance time for the additional work required by paragraph (2) of EASA AD 2019- 0196. AAL asked that the compliance time be changed from within 108 months to within 120 months (10 years) from the date of aircraft manufacture due to the nature of the work, andin order for affected airplanes to do the work at the next scheduled heavy maintenance check opportunity. \n\tThe FAA does not agree with the commenter's request to extend the compliance time. AAL did not provide information showing that the revised compliance time would provide an adequate level of safety. The FAA has determined that the 108-month compliance time in EASA AD 2019- 0196 addresses the identified unsafe condition in a timely manner. In developing an appropriate compliance time, EASA considered the degree of urgency associated with addressing the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the additional work. The FAA has determined that the compliance time specified in EASA AD 2019-0196 represents an appropriate interval of time for affected airplanes to continue to operate without compromising safety. However, under the provisions of paragraph (i)(1) of this AD, the FAA will consider requests for approval ofan extension of the compliance time if sufficient data are submitted to substantiate that the new compliance time would provide an acceptable level of safety. The AD has not been changed in this regard. \n\nConclusion \n\n\n\tThe FAA has reviewed the relevant data, considered the comment received, 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 IBR Material Under 1 CFR Part 51 \n\n\n\tEASA AD 2019-0196 describes procedures for a one-time eddy current conductivity measurement of certain cabin, cargo compartment, and frame structural parts to determine if aluminum alloy with inadequate heat treatment was used, and replacement if necessary. EASA AD 2019-0196 also describes, for certain airplanes, additional work (a one-time eddy current conductivity measurement of certain other structural parts, and replacement if necessary). 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\nCosts of Compliance \n\n\n\tThe FAA estimates that this AD affects 63 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: \n\n((Page 21761)) \n\n\n\n\n\n\n\tEstimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- \n\tCost on U.S. \n\tAction Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Retained actions from AD 2017-05- 6 work-hours x $85$0 $510............... $32,130. \n\t12. per hour = $510. New actions...................... Up to 7 work-hours $0 Up to $595......... Up to $37,485. \n\tx $85 per hour = \n\tUp to $595. ---------------------------------------------------------------------------------------------------------------- \n\n\n\tThe FAA has received no definitive data that enables the agency to provide cost estimates for the on-condition actions specified in this AD. \n\tAccording to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate. \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.For 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.
