Airworthiness Directive · Amendment 39-21181 · Emergency flotation section
Leonardo S.p.A. Helicopters
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.
The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. 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.
(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.
(2) A “serviceable part” is an affected part that has been corrected in accordance with the Accomplishment Instructions of ASB 139-533; ASB 169-099; or ASB 189-195; as applicable; or a part that is not affected.
At the applicable compliance time specified in Figure 2 to paragraph (h) of this AD, remove each affected part from the helicopter and install a serviceable part. This may be done in accordance with the Accomplishment Instructions of ASB 139-533; ASB 169-099; or ASB 189-195; as applicable.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
