 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2021-0796; Project Identifier MCAI-2021-00098-R]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS355NP helicopters. This proposed AD was prompted by a report of mechanical deformation found on the protective cover (also referred to as switch guard) of the “SHEAR” control pushbutton installed on a co-pilot collective stick of a Model EC225LP helicopter, caused by incorrect handling; due to having an identical design switch guard installed on the pilot collective stick, Model AS355NP helicopters are also affected. This proposed AD would require replacement of the protective cover of the “SHEAR” control pushbutton, and re-identification of the pilot collective stick, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). 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 November 8, 2021.

Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0027R1, dated January 22, 2021 (EASA AD 2021-0027R1), to correct an unsafe condition for all Airbus Helicopters (formerly Eurocopter) Model AS355NP helicopters. This proposed AD was prompted by a report of mechanical deformation found on the protective cover of the “SHEAR” control pushbutton installed on a co-pilot collective stick of a Model EC225LP helicopter, caused by incorrect handling; due to having an identical design switch guard installed on the pilot collective stick, Model AS355NP helicopters are also affected. The FAA is proposing this AD to address mechanical deformation on the protective cover of the “SHEAR” control pushbutton installed on the pilot collective stick. The unsafe condition, if not addressed, could result in unintended shearing of the hoist cable, possibly resulting in injury to hoisted person(s). See EASA AD 2021-0027R1 for additional background information. FAA AD 2020-15-15, Amendment 39-21178 (85 FR 45765, July 30, 2020), which was prompted by EASA AD 2018-0106, dated May 10, 2018, addresses the unsafe condition for Airbus Helicopters (formerly Eurocopter, Eurocopter France, and Aerospatiale) Model EC225LP helicopters. Related Service Information Under 1 CFR Part 51 EASA AD 2021-0027R1 requires replacement of the protective cover of the “SHEAR” control pushbutton, and re-identification of the pilot collective stick. This 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. FAA's Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA's bilateral agreement with the 
                    ( print page 52855)
                    European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in EASA AD 2021-0027R1, 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 2021-0027R1 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2021-0027R1 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 2021-0027R1 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 2021-0027R1. Service information required by EASA AD 2021-0027R1 for compliance will be available at 
                    *https://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2021-0796 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 2 helicopters of U.S. registry. Based on these numbers, the FAA estimates the following costs to comply with this proposed AD: Estimated Costs for Required Actions
Labor cost
Parts cost
Cost per
                             product
Cost on U.S.
                             operators2 work-hours × $85 per hour = $170
$360
$530
$1,060
 According to the manufacturer, some or all of the costs of this proposed 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. 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) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
