AD 2021-09-13

The FAA is superseding Airworthiness Directives (AD) 2000-23- 04 R1 and AD 2018-20-14, which applied to certain ATR-GIE Avions de Transport Regional Model ATR42-500 airplanes. AD 2000-23-04 R1 and AD 2018-20-14 required revising the maintenance or inspection program, as applicable, to incorporate new and/or more restrictive maintenance requirements and airworthiness limitations. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by the FAA's determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products.

Final rule.

Background \n\n\n\tEASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0263, dated December 1, 2020 (EASA AD 2020-0263) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Model ATR 42-400 and ATR 42-500 airplanes. Model ATR 42-400 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. Airplanes with an original airworthiness certificate or original export certificate of airworthiness issued after July 7, 2020 must comply with the airworthiness limitations specified as part of the approved type design and referenced on the type certificate data sheet; this AD therefore does not include those airplanes in the applicability. \n\tThe FAA issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part39 to supersede AD 2000-23-04 R1, Amendment 39- 12174 (66 FR 19381, April 16, 2001) (AD 2000-23-04 R1) and AD 2018-20- 14, Amendment 39-19448 (83 FR 52123, October 16, 2018) (AD 2018-20-14). ADs 2000-23-04 R1 and 2018-20-14 applied to certain ATR-GIE Avions de Transport Regional Model ATR42-500 airplanes. The SNPRM published in the Federal Register on February 24, 2021 (86 FR 11169). The FAA preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on October 29, 2020 (85 FR 68503). The NPRM was prompted by the FAA's determination that new or more restrictive airworthiness limitations are necessary. The NPRM proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The SNPRM proposed to require revising the existing \n\n((Page 27032)) \n\nmaintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in EASA AD 2020-0263. \n\tThe FAA is issuing this AD to address reduced structural integrity of the airplane. 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 FAA received no comments on the SNPRM or on the determination of the cost to the public. \n\nConclusion \n\n\n\tThe FAA reviewed the relevant data 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 SNPRM for addressing the unsafe condition; and \n\tDo not add any additional burden upon the public than was already proposed in the SNPRM. \n\tThe FAA also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule. \n\nRelated Service Information Under 1 CFR Part 51 \n\n\n\tEASA AD 2020-0263 describes new or more restrictive airworthiness limitations for airplane structures and safe life limits. \n\tThis AD also requires the following service information, which the Director of the Federal Register approved for incorporation by reference as of November 20, 2018 (83 FR 52123, October 16, 2018). \n\tATR ATR42-400/-500, Time Limits Document (TL), Revision 11, dated May 5, 2015. \n\tATR ATR42-400/-500 Time Limits Temporary Revision TR01/17, dated May 3, 2017. \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 9 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: \n\tThe FAA estimates the total cost per operator for the retained actions from AD 2018-20-14 to be $7,650 (90 work-hours x $85 per work- hour).The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 work-hours per operator, although the agency recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. \n\tThe FAA estimates the total cost per operator for the new actions to be $7,650 (90 work-hours x $85 per work-hour). \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. \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.
