That AD applies to certain Leonardo S.p.A. (Leonardo) Model AB139, AW139, AW169, and AW189 helicopters. As published, one service bulletin reference in the AD is incorrect. This document corrects that error. In all other respects, the original document remains the same. ## The airworthiness directive 1. The authority citation for part 39 continues to read as follows: 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): 2020-15-18 Leonardo S.p.A.: Amendment 39-21181; Docket No. FAA-2020-0215; Product Identifier 2018-SW-088-AD. ### (a) Effective Date This AD is effective September 3, 2020. ### (b) Affected ADs None. ### (c) Applicability This AD applies to the Leonardo S.p.A. helicopters identified in paragraphs (c)(1) through (3) of this AD, certificated in any category. (1) Model AB139 and AW139 helicopters, all serial numbers, equipped with an emergency flotation system (EFS) float assembly having part number (P/N) 3G9560V00332, 3G9560V00432, 3G9560V01432, or 3G9560V01532. (2) Model AW169 helicopters, all serial numbers, equipped with an EFS float assembly having any part number. (3) Model AW189 helicopters, all serial numbers, equipped with an EFS float assembly having P/N 8G9560V00331 or 8G9560V00431. ### (d) Subject Joint Aircraft Service Component (JASC) Code 3212, Emergency Flotation Section. ### (e) Reason This AD was prompted by reports of uncommanded deployment of the EFS due to improper accomplishment of the reset procedure of the shape memory alloy (SMA) inflation system actuation device. The FAA is issuing this AD to address uncommanded EFS deployment, which could result in reduced control of the helicopter. ### (f) Compliance Comply with this AD within the compliance times specified, unless already done. ### (g) Definitions (1) An “affected part” is an SMA inflation system having P/N 3G9560V01052 (Model AB139 and AW139 helicopters), P/N 6F9560V00551 (Model AW169 helicopters), or P/N 8G9560V01751 (Model AW189 helicopters), as applicable, with a serial number specified in Figure 1 to paragraph (g)(1) of this AD except those which have been corrected in accordance with the Accomplishment Instructions of Leonardo Helicopters Alert Service Bulletin (ASB) No. 139-533, dated August 30, 2018 (ASB 139-533); Leonardo Helicopters ASB No. 169-099, dated August 30, 2018 (ASB 169-099); or Leonardo Helicopters ASB No. 189-195, dated August 30, 2018 (ASB 189-195); as applicable.

It is also available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-0215. ### For further information contact Kristi Bradley, Aviation Safety Engineer, Safety Management Section, Rotorcraft Standards Branch, FAA, 10101 Hillwood Pkwy., Fort Worth, TX 76177; telephone 817-222-5485; email Kristin.Bradley@faa.gov. ### SUPPLEMENTARY INFORMATION AD 2020-15-18, Amendment 39-21181 (85 FR 45773, July 30, 2020) (AD 2020-15-18), currently requires removal of affected shape memory alloy (SMA) inflation systems and installation of serviceable SMA inflation systems. That AD applies to certain Leonardo S.p.A. (Leonardo) Model AB139, AW139, AW169, and AW189 helicopters. ### Need for the Correction As published, paragraph (g) of the regulatory text of AD 2020-15-18 contains an error in a reference to the service information. Paragraph (g) of the AD incorrectly identifies the service information “Alert Service Bulletin (ASB) No. 139-533, dated August 30, 2018 (ASB-139-153)”. The second parenthetical reference to “ASB-139-153” is incorrect. ### 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. ### Correction of Publication This document corrects an error and correctly adds the AD as an amendment to 14 CFR 39.13. Although no other part of the preamble or regulatory information has been corrected, the FAA is publishing the entire rule in the Federal Register. The effective date of this AD remains September 3, 2020. ### Good Cause for Adoption Without Prior Notice Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq.) authorizes agencies to dispense with notice and comment procedures for rules when the agency for “good cause” find that those procedures are “impracticable, unnecessary, or contrary to the public interest.” Section 553(d)(3) of the APA requires that agencies publish a rule not less than 30 days before its effective date, except as otherwise provided by the agency for good cause found and published with the rule. Since this action only corrects a typographical error in a service bulletin reference, it has no adverse economic impact and imposes no additional burden on any person. Therefore, the FAA has determined that notice and public comment procedures under 5 U.S.C. 553(b) are unnecessary. For the same reason, the FAA finds that good cause exists under 5 U.S.C. 553(d) for making this rule effective in less than 30 days. ### Adoption of the Correction Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: ## Affected data sheets (3) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS R00002RD](https://openairdocs.org/tcds/R00002RD): Leonardo S.p.a.; names 2 of 2 models: AW139, AB139 - [TCDS R00004RD](https://openairdocs.org/tcds/R00004RD): Leonardo S.p.A.; names 1 of 1 models: AW189 - [TCDS R00007RD](https://openairdocs.org/tcds/R00007RD): Leonardo S.p.a.; names 1 of 1 models: AW169 ## Registered aircraft it may apply to (OpenAirDocs) Matched by airframe and engine model; the AD's applicability may narrow it by serial number, part number or equipment. - Aircraft: 192 (192 by airframe model, 0 by engine model) - Makers: Agustawestland Philadelphia 99, Leonardo 33, Agusta 22, Agusta Aerospace 21, Leonardo Helicopters US 6, Agustawestland 5, Leonardo S P A 5, Agustawestland S P A 1 Models with the most aircraft: - [Agustawestland Philadelphia AW139](https://openairdocs.org/model/agustawestland-philadelphia-aw139): 99 aircraft (airframe model) - [Agusta Aerospace AW139](https://openairdocs.org/model/agusta-aerospace-aw139): 21 aircraft (airframe model) - [Leonardo AW169](https://openairdocs.org/model/leonardo-aw169): 20 aircraft (airframe model) - [Agusta AW139](https://openairdocs.org/model/agusta-aw139): 14 aircraft (airframe model) - [Leonardo AW139](https://openairdocs.org/model/leonardo-aw139): 13 aircraft (airframe model) - [Agusta AB139](https://openairdocs.org/model/agusta-ab139): 8 aircraft (airframe model) - [Leonardo Helicopters US AW139](https://openairdocs.org/model/leonardo-helicopters-us-aw139): 6 aircraft (airframe model) - [Leonardo S P A AW189](https://openairdocs.org/model/leonardo-s-p-a-aw189): 4 aircraft (airframe model) - [Agustawestland AW139](https://openairdocs.org/model/agustawestland-aw139): 3 aircraft (airframe model) - [Agustawestland AW189](https://openairdocs.org/model/agustawestland-aw189): 2 aircraft (airframe model) - [Agustawestland S P A AW169](https://openairdocs.org/model/agustawestland-s-p-a-aw169): 1 aircraft (airframe model) - [Leonardo S P A AB139](https://openairdocs.org/model/leonardo-s-p-a-ab139): 1 aircraft (airframe model) All 12 models: https://openairdocs.org/ad/2020-15-18/models.md Every aircraft: https://openairdocs.org/ad/2020-15-18/aircraft.md ## Related documents - [Proposed rule FAA-2020-0215](https://openairdocs.org/proposed/FAA-2020-0215): Notice of proposed rulemaking (NPRM), published Apr 14, 2020 Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
