Discussion \n\n\n\tThe EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0106, dated May 15, 2019 (''EASA AD 2019-0106'') (also referred to as the Mandatory Continuing Airworthiness Information, or ''the MCAI''), to correct an unsafe condition for certain Airbus SAS Model A319-112, A319-115, A319-132, A320-214, A320-216, A320-232, A320-233, A320-251N, A320-271N, A321-211, A321-231, A321-232, A321-251N, and A321-253N airplanes. \n\tThe FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus SAS Model A319-112, A319-115, A319-132, A320-214, A320-216, A320-232, A320- 233, A320-251N, A320-271N, A321-211, A321-231, A321-232, A321-251N, and A321-253N airplanes. The NPRM published in the Federal Register on August 30, 2019 (84 FR 45692). The NPRM was prompted by reports of finding container/galley end stop bumpers damaged in service. The NPRMproposed to require replacement of the affected bumpers with serviceable bumpers. \n\tThe FAA is issuing this AD to address deformed end stops, which could break or lose their function to maintain the container/galley in position on the airplane. This condition, if not corrected, could lead to container/galley detachment under certain forward loading conditions, possibly resulting in injury to airplane occupants. 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 comment received on the NPRM and the FAA's response to the comment. \n\nRequest To Change the Service Information \n\n\n\tAmerican Airlines (AAL) requested that certain service information be changed to restrict installation of the containers in related compartments only during the adhesive cure time, rather than the specified 168 hours (7 days) after completion of certain tasks and to provide analternative adhesive compound with a faster cure time that does not require heat. AAL stated that requirements related to the specified adhesive cure time would necessitate an unacceptable amount of aircraft downtime, which could jeopardize its ability to comply within the proposed compliance time. \n\tThe FAA disagrees. The FAA and EASA both have concluded that 48 months after the effective date of the AD is sufficient time for operators to plan and execute compliance requirements to mitigate the unsafe condition. Regarding the requirement to wait 168 hours before installing containers, the FAA notes that only certain compartments are affected. Operators who wish to install containers in those affected compartments in less than 168 hours may request an alternative method of compliance (AMOC) in accordance with paragraph (i)(1) of this AD, including providing sufficient data to substantiate that installing the containers in less than 168 hours would provide an acceptable level of safety. In addition, Safran is reportedly in the process of certifying an alternative adhesive with accelerated cure time, followed by changes to their service bulletin. However, to delay this AD action while Safran works toward certification of an alternative adhesive and releases revised service information would be inappropriate, since the FAA has determined that an unsafe condition exists and that sufficient technology currently exists to accomplish the required actions within the required compliance time. Once the alternative adhesive and revised service information are approved, operators may request to use the alternative adhesive and revised service information by using the AMOC provision provided in paragraph (i)(1) of this AD and submitting sufficient data to substantiate that the alternative adhesive would provide an acceptable level of safety. The FAA has not changed this AD in this regard. \n\nConclusion \n\n\n\tThe FAA reviewed the relevant data, considered the comment received,and determined that air safety and the public interest require adopting this \n\n((Page 6756)) \n\nfinal 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 2019-0106 describes procedures for modification of the affected galleys by replacement of the affected bumpers with serviceable bumpers. \n\tThis 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 274 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\tLabor cost Parts cost Cost per product Cost on U.S. operators ---------------------------------------------------------------------------------------------------------------- Up to 54 work-hours x $85 per hour = $0 Up to $4,590........... Up to $1,257,660. \n\tUp to $4,590. ---------------------------------------------------------------------------------------------------------------- \n\n\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\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 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. \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 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.
