Airworthiness Directives; Airbus Helicopters
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS355NP helicopters. This AD requires removing and installing the fire extinguishing system pipes. This AD is prompted by the discovery that the left-hand and right-hand fire extinguishing discharge systems were incorrectly connected. The actions of this AD are intended to correct the unsafe condition on these products.
