AD 2021-05-15

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD was prompted by a report that the cabin lateral sliding plug door failed its emergency jettisoning test; subsequent investigation revealed that the jettison handle cable interfered with the cable clamps. This AD requires modifying the release system of each cabin lateral sliding plug door, or modifying the design of the jettison system of each cabin lateral sliding plug door, as specified in a European Union Aviation Safety Agency (EASA) AD, which is 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. 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. The FAA amends Sec. 39.13 by adding the following new airworthiness directive: \n\n2021-05-15 Airbus Helicopters: Amendment 39-21458; Docket No. FAA- 2020-0909; Project Identifier 2019-SW-118-AD. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) is effective May 7, 2021. \n\n(b) Affected ADs \n\n\n\tThis AD affects AD 2019-09-03, Amendment 39-19637 (84 FR 22693, May 20, 2019) (AD 2019-09-03). \n\n(c) Applicability \n\n\n\tThis AD applies to Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2019- 0064R1, dated December 19, 2019 (EASA AD 2019-0064R1). \n\n(d) Subject \n\n\n\tJoint Aircraft System Component (JASC) Code 5200, Doors. \n\n(e) Reason \n\n\n\tThis AD was prompted by a report that the cabin lateral sliding plug door failed its emergency jettisoning test; subsequent investigation revealed that the jettison handle cable interfered with the cable clamps.

Discussion \n\n\n\tThe EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0064R1, dated December 19, 2019 (EASA AD 2019-0064R1) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. \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 Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. The NPRM published in the Federal Register on October 7, 2020 (85 FR 63238). The NPRM was prompted by a report that the cabin lateral sliding plug door failed its emergency jettisoning test; subsequent investigation revealed that the jettison handle cable interfered with the cable clamps. The NPRM proposed to require modifying the release system of each cabin lateral sliding plug door, or modifying the design of the jettison system of each cabin lateral sliding plug door, as specified in EASA AD 2019-0064R1, which is incorporated by reference. \n\tThe FAA is issuing this AD to address this condition, which could lead to jamming of the door jettisoning mechanism, preventing the jettisoning of the affected door in an emergency situation, and possibly obstructing occupant evacuation. 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. The commenter indicated support for the NPRM. \n\n((Page 17291)) \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 IBR Material Under 1 CFR Part 51 \n\n\n\tEASA AD 2019-0064R1 describes, among other things, procedures for modifying the release system of each cabin lateral sliding plug door, or modifying the design of the jettison system of each cabin lateral sliding plug door. \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\nDifferences Between This AD and the MCAI \n\n\n\tEASA AD 2019-0064R1 specifies inspections of the jettisoning mechanism of the cabin lateral sliding plug doors and corrective actions. This AD does not include those actions. AD 2019-09-03, Amendment 39-19637 (84 FR 22693, May 20, 2019) (AD 2019-09-03) already requires those actions. The FAA has determined that this AD will only require the modification specified in EASA AD 2019-0064R1, which would then terminate the requirements of AD 2019-09-03. \n\nCosts of Compliance \n\n\n\tThe FAA estimates that this AD affects 19 helicopters 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 214 work-hours x $85 per hour = $ * Up to $18,190............. Up to $345,610. \n\tUp to $18,190. ---------------------------------------------------------------------------------------------------------------- \n* The FAA has received no definitive data that would enable the agency to provide parts cost estimates for the\n\n\tactions 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.
