Airworthiness Directives; Agusta S.p.A. (Type Certificate Currently Held by AgustaWestland S.p.A.) (Agusta) Helicopters
Summary
We are adopting a new airworthiness directive (AD) for Agusta AB139 and AW139 helicopters to require replacing certain single-braided flexible hydraulic hoses with double-braided flexible hydraulic hoses. This AD was prompted by occurrences of leaking flexible hydraulic hoses. The actions of this AD are intended to prevent loss of hydraulic power and subsequent loss of helicopter control.
