## Abstract

We are superseding Airworthiness Directive (AD) 2016-25-19 for Airbus Helicopters (previously Eurocopter France) Model AS350B3 and EC130B4 helicopters. AD 2016-25-19 required inspecting the pilot's and co-pilot's throttle twist for proper operation. This new AD retains the requirements of AD 2016-25-19 and adds certain model helicopters to the applicability. The actions of this AD are intended to address an unsafe condition on these products.
