Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters

Resumen

We are superseding airworthiness directive (AD) 2010-21-07 for Eurocopter France (now Airbus Helicopters) Model AS350B3 and EC130B4 helicopters. AD 2010-21-07 required inspecting the pilot's and co- pilot's throttle twist for proper operation of the contactors. This new AD retains the requirements of AD 2010-21-07, includes additional inspection procedures, and revises the inspection interval. These actions are intended to address the unsafe condition on these products.
