 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2022-0503; Project Identifier MCAI-2021-01244-T]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2018-03-12, which applies to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2018-03-12 requires repetitive rototest inspections for cracking of the fastener holes in certain door stop fittings, and repair if necessary. Since the FAA issued AD 2018-03-12, new analysis by the manufacturer resulted in optimized compliance times for the inspections. This proposed AD would require repetitive rototest inspections for cracking of the fastener holes in certain door stop fittings at revised compliance times, and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
 DATES: The FAA must receive comments on this proposed AD by June 21, 2022.

Discussion The FAA issued AD 2018-03-12, Amendment 39-19185 (83 FR 5906, February 12, 2018) (AD 2018-03-12), which applies to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2018-03-12 requires repetitive rototest inspections for cracking of the fastener holes in certain door stop fittings, and repair if necessary. The FAA issued AD 2018-03-12 to address cracking at the door stop fitting holes of fuselage frame (FR) 66 and FR68. Such cracking could result in reduced structural integrity of the airplane due to the failure of structural components. Actions Since AD 2018-03-12 Was Issued Since the FAA issued AD 2018-03-12, Airbus has revised the compliance times to accomplish the rototest inspections based on reports from operators and new analysis. EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0242, dated November 8, 2021 (EASA AD 2021-0242) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -215, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. EASA AD 2021-0242 supersedes EASA AD 2016-0238 (which corresponds to FAA AD 2018-03-12). Model A320-215 airplanes are not certificated 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. This proposed AD was prompted by reports of fatigue damage in the structure for the door stop fittings on certain fuselage frames. The FAA is proposing this AD to address cracking at the door stop fitting holes of fuselage FR66 and FR68 which could result in reduced structural integrity of the airplane. See the MCAI for additional background information. Model A320-216 Airplanes The Airbus SAS Model A320-216 was U.S. type certificated on December 19, 2016. Before that date, any EASA ADs that affected Model A320-216 airplanes were included in the U.S. type certificate as part of the Required Airworthiness Actions List (RAAL). One or more Model A320-216 airplanes have subsequently been placed on the U.S. Register, and will now be included in FAA AD actions. For Model A320-216 airplanes, the requirements that correspond to AD 2018-03-12 were mandated by the MCAI via the RAAL. Although that RAAL requirement is still in effect, for continuity and clarity the FAA has identified Model A320-216 airplanes in paragraph (c) of this proposed AD; the MCAI that is specified in paragraph (g) in this proposed AD includes retained requirements, which would therefore apply to those airplanes. Explanation of Retained Requirements Although this proposed AD does not explicitly restate the requirements of AD 2018-03-12, this proposed AD would retain all of the requirements of  AD 2018-03-12. Those requirements are referenced in EASA AD 2021-0242, which, in turn, is referenced in paragraph (g) of this proposed AD. Related Service Information Under 1 CFR Part 51 EASA AD 2021-0242 describes procedures for rototest inspections for cracking of the fastener holes in the airframe structure for the door stop fittings installation in FR66 and FR68, and corrective actions. Corrective actions include repair or modification of fastener holes at door stop locations.

                    **ADDRESSES**
                     section. FAA's Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is proposing this AD because the FAA evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 2021-0242 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD. Explanation of Required Compliance Information In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate EASA AD 2021-0242 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2021-0242 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2021-0242 does not mean that operators need comply only with that section. For example, where the AD requirement refers to “all required actions and compliance times,” compliance with this AD requirement is not limited to the section titled “Required Action(s) and Compliance Time(s)” in EASA AD 2021-0242. Service information required by EASA AD 2021-0242 for compliance will be available at 
                    *https://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2022-0503 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 1,084 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD:

 The FAA has received no definitive data on which to base the cost estimates for the on-condition repairs specified in this proposed AD. 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. The 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. Regulatory Findings The FAA 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 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) Will not affect intrastate aviation in Alaska, and (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.
