Leonardo S.p.a. Helicopters
This Airworthiness Directive (AD) applies to Leonardo S.p.a. (Leonardo) Model AB139 and AW139 helicopters, serial number (S/N) 31400 through 31882 inclusive, and S/N 41300 through 41570 inclusive, certificated in any category, with one or two forward facing first row center seat/seats (seat) and a cabin floor composed of 3 panels, and identified by configuration in Figures 1 through 13 of Leonardo Alert Service Bulletin No. 139-633, Rev. A, dated September 2, 2020 (ASB 139-633) installed.
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. (Leonardo) Model AB139 and AW139 helicopters. This AD requires removing certain forward facing center seats (seats). This AD was prompted by a design deficiency that affects seats on certain main cabin floor installations. The actions of this AD are intended to address an unsafe condition on these products.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Remove each seat within 50 hours time-in-service.
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.
