                AGENCY: Federal Aviation Administration (FAA), DOT.
                ACTION: Notice of proposed rulemaking (NPRM).
                -----------------------------------------------------------------------
                SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
                for certain Leonardo S.p.A. (Leonardo) Model AB139, AW139, AW169, and
                AW189 helicopters. This proposed AD was prompted by reports of
                uncommanded deployment of the emergency flotation system (EFS) due to
                improper accomplishment of the reset procedure of the shape memory
                alloy (SMA) inflation system actuation device. This proposed AD would
                require removal of affected SMA inflation systems and installation of
                serviceable SMA inflation systems. 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 May 29,
                2020.
                ADDRESSES: You may send comments, using the procedures found in 14 CFR

                SUPPLEMENTARY INFORMATION:
                Comments Invited
                 The FAA invites you to send any written relevant data, views, or
                arguments about this proposal. Send your comments to an address listed
                under the ADDRESSES section. Include ``Docket No. FAA-2020-0215;
                Product Identifier 2018-SW-088-AD'' at the beginning of your comments.
                The FAA specifically invites comments on the overall regulatory,
                economic, environmental, and energy aspects of this NPRM. The FAA will
                consider all comments received by the closing date and may amend this
                NPRM because of those comments.
                 The FAA will post all comments received, without change, to https://www.regulations.gov, including any personal information you provide.
                The FAA will also post a report summarizing each substantive verbal
                contact received about this NPRM.
                Discussion
                 EASA, which is the Technical Agent for the Member States of the
                European Union, has issued EASA AD 2018-0208, dated September 20, 2018
                (referred to after this as the Mandatory Continuing Airworthiness
                Information, or ``the MCAI''), to correct an unsafe condition for
                certain Leonardo Model AB139, AW139, AW169, and AW189 helicopters. EASA
                advises that reports were received of uncommanded EFS deployment on
                Model AW139, AW169, and AW189 helicopters. Results of the subsequent
                technical investigation revealed that these events may have been caused
                by the improper accomplishment of the reset procedure of the SMA
                inflation system actuation device. EASA added that these events may
                lead to an unstable condition of the SMA inflation system. This
                condition, if not addressed, could lead to further events of
                uncommanded EFS deployment, possibly resulting in reduced control of
                the helicopter.
                 You may examine the MCAI in the AD docket on the internet at
                https://www.regulations.gov by searching for and locating Docket No.
                FAA-2020-0215.
                Related Service Information Under 1 CFR Part 51
                 Leonardo Helicopters has issued Alert Service Bulletin (ASB) No.
                139-533, dated August 30, 2018; ASB No. 169-099, dated August 30, 2018;
                and ASB No. 189-195, dated August 30, 2018. This service information
                describes procedures for removal of affected SMA inflation systems and
                installation of serviceable SMA inflation systems (including correcting
                the SMA inflation system by performing a reset procedure). These
                documents are distinct since they apply to different helicopter models.
                 This service information 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
                 This product has been approved by the aviation authority of another
                country, and is approved for operation in the United States. Pursuant
                to the FAA's bilateral agreement with the State of Design Authority,
                the FAA has been notified of the unsafe condition described in the MCAI
                and service information referenced above. The FAA is proposing this AD
                after evaluating all the relevant information and determining the
                unsafe condition described previously is likely to exist or develop on
                other products of the same type design.
                Proposed Requirements of This NPRM
                 This proposed AD would require accomplishing the actions specified
                in the service information described previously.
                Costs of Compliance
                 The FAA estimates that this proposed AD affects 138 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. operators
                ----------------------------------------------------------------------------------------------------------------
                Up to 7 work-hours x $85 per hour = $ *.................... Up to $595 *........... Up to $82,110 *
                 Up to $595.
                ----------------------------------------------------------------------------------------------------------------
                * The FAA has received no definitive data that would enable the FAA to provide parts cost estimates for the
                 actions specified in this proposed AD.
                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
                [[Page 20620]]
                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.
