AD FAA-2015-3969

Airworthiness Directives; Agusta S.p.A. Helicopters

Summary

We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB412 helicopters. This AD requires inspecting the filters installed on the pressure lines of utility hydraulic systems for metal particles. This AD is prompted by a report of a pump failure on the hydraulic external hoist caused by metal particles. These actions are intended to detect metal particles in the filter of the pressure line and prevent the pumps' failure, which could lead to a hoisting accident and injury to persons.
