AD 2020-23-11

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A300 series airplanes; and Airbus SAS Model A300 B4- 600, B4-600R, and F4-600R series airplanes, and Airbus SAS Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This AD was prompted by reports of cracking at a certain hole location on the left-hand (LH) side of a certain frame (FR). This AD requires repetitive inspections for discrepancies of certain areas in and around the fuselage, as specified in two European Union Aviation Safety Agency (EASA) ADs, which are incorporated by reference. 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.

Discussion \n\n\n\tThe EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0110R1, dated May 27, 2020; and EASA AD 2020-0111R2, dated June 16, 2020 (''EASA AD 2020-0110R1'' and ''EASA AD 2020-0111R2'') (also \n\n((Page 75839)) \n\nreferred to as ''the Mandatory Continuing Airworthiness Information,'' or ''the MCAI''); to correct an unsafe condition for all Airbus SAS Model A300 series airplanes and Airbus SAS Model A300-600 series 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 all Airbus SAS Model A300 series airplanes and Airbus SAS Model A300-600 series airplanes. The NPRM published in the Federal Register on September 1, 2020 (85 FR 54286). The NPRM was prompted by reports of cracking at hole location #10 on the LH side of FR4. The NPRM proposed to require repetitive inspections for discrepancies of certain areas in and around the fuselage, as specified in two EASA ADs. \n\tThe FAA is issuing this AD to address fatigue cracking, which could result in reduced structural integrity of the fuselage. 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 has considered the comment received. FedEx indicated its support for the NPRM. \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 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 Service Information Under 1 CFR Part 51 \n\n\n\tEASA AD 2020-0110R1 describes procedures for repetitive special detailed inspections for discrepancies (i.e., cracking) of the fuselage internal structure at certain frames, windshield frame lower section and closing panel, fuselage skin lap joint, and center wing bottom skin internal angle; and applicable corrective actions (repairing discrepancies). \n\tEASA AD 2020-0111R2 describes procedures for repetitive special detailed inspections for discrepancies of the outer wing bottom skin internal joint plate, outer wing bottom skin, fuselage internal structure at certain frames, and windshield frame lower section and closing panel; and applicable corrective actions (repairing discrepancies). \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 118 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:Estimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- \n\tCost per Cost on U.S. \n\tLabor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- 90 work-hours x $85 per hour = $7,650........................ $0 $7,650 $902,700 ---------------------------------------------------------------------------------------------------------------- \n\n\n\tThe FAA has received no definitive data that would enable the agency to provide cost estimates for the on-condition actions specified in this AD. \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.
