 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2020-1119; Project Identifier 2019-SW-089-AD]
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 EC 155B and EC155B1 helicopters. This proposed AD was prompted by a report of mechanical deformation of the protective cover of the “SHEAR” control pushbutton on the copilot collective stick. This proposed AD would require replacement of the protective cover of the “SHEAR” control pushbutton on the pilot and copilot collective sticks and re-identification of the pilot and copilot collective sticks, 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 March 1, 2021.

Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0246, dated October 1, 2019 (EASA AD 2019-0246) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus Helicopters Model EC 155B and EC155B1 helicopters. This proposed AD was prompted by a report of mechanical deformation of the protective cover of the “SHEAR” control pushbutton on the copilot collective stick of an EC 225 LP helicopter from incorrect handling. The FAA has determined that Model EC 
                    ( print page 3884)
                    155B and EC155B1 helicopters are also affected due to an identical switch guard design. The FAA is proposing this AD to address mechanical deformation of the protective cover of the “SHEAR” control pushbutton on the copilot collective stick, which could lead to un-commanded shearing of the hoist cable and possible injury to hoisted person(s). See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2019-0246 describes procedures for replacement of the protective cover of the “SHEAR” control pushbutton on the pilot and copilot collective sticks and re-identification of the pilot and copilot collective sticks. 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 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 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 the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 2019-0246, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD and except as discussed under “Differences Between this Proposed AD and the MCAI.” Explanation of Required Compliance Information In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, EASA AD 2019-0246 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2019-0246 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 the EASA AD 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 the EASA AD. Service information specified in EASA AD 2019-0246 that is required for compliance with EASA AD 2019-0246 will be available on the internet at 
                    *https://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2020-1119 after the FAA final rule is published. Differences Between This Proposed AD and the MCAI Where paragraph (1) of EASA AD 2019-0246 refers to a table for the compliance time for the modification, for this proposed AD, the compliance time for the modification is before any hoist operations after the effective date of this AD but no later than 3 months after the effective date of this AD. Costs of Compliance The FAA estimates that this proposed AD affects 17 helicopters of U.S. registry. 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
$2,446
$2,616
$44,472
 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 operators. The FAA does not control warranty coverage for affected operators. 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) 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.

 The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, 
                    ( print page 3885)
                    the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES
 1.The authority citation for part 39 continues to read as follows: Authority:
                    49 U.S.C. 106(g), 40113, 44701. § 39.13
 2.The FAA amends § 39.13 by adding the following new airworthiness directive: **Airbus Helicopters:**
                         Docket No. FAA-2020-1119; Project Identifier 2019-SW-089-AD. (a) Comments Due Date The FAA must receive comments by March 1, 2021. (b) Affected Airworthiness Directives (ADs) None. (c) Applicability This AD applies to all Airbus Helicopters Model EC 155B and EC155B1 helicopters, certificated in any category. (d) Subject Joint Aircraft System Component (JASC) Code 6700, Rotorcraft flight control. (e) Reason This AD was prompted by a report of mechanical deformation of the protective cover of the “SHEAR” control pushbutton on the copilot collective stick. The FAA is issuing this AD to address mechanical deformation of the protective cover of the “SHEAR” control pushbutton on the copilot collective stick, which could lead to un-commanded shearing of the hoist cable and possible injury to hoisted person(s). (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2019-0246, dated October 1, 2019 (EASA AD 2019-0246). (h) Exceptions to EASA AD 2019-0246 (1) Where EASA AD 2019-0246 refers to its effective date, this AD requires using the effective date of this AD. (2) The “Remarks” section of EASA AD 2019-0246 does not apply to this AD. (3) Where the service information referenced in EASA AD 2019-0246 specifies to use tooling, equivalent tooling may be used. (4) Where paragraph (1) of EASA AD 2019-0246 refers to a table for the compliance time for the modification, for this AD, the compliance time for the modification is before the first hoist operation done after the effective date of this AD but no later than 3 months after the effective date of this AD. (5) Although the service information referenced in EASA 2019-0246 specifies to discard certain parts, this AD does not include that requirement. (i) Special Flight Permit Special flight permits may be issued in accordance with 14 CFR 21.197 and 21.199 to operate the helicopter to a location where the helicopter can be modified (if the operator elects to do so), provided the helicopter is not used for hoist operations and no passengers are onboard. (j) Alternative Methods of Compliance (AMOCs): The Manager, Rotorcraft Standards Branch, FAA, may approve AMOCs for this AD.
