Airworthiness Directives; Eurocopter France (Eurocopter) Helicopters

Riepilogo

We are adopting a new airworthiness directive (AD) for Eurocopter Model SA-365N, SA-365N1, AS-365N2, AS 365 N3, EC 155B, EC155B1, AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters with certain EADS Sogerma pilot and co-pilot seats installed. This AD requires inspecting the rear beam of each seat to determine if all of the weld beads are present and replacing the seat if any weld bead is missing. This AD is prompted by a maintenance inspection that discovered a missing weld bead on the rear beam of a pilot seat. These actions are intended to prevent failure of the pilot and co-pilot seats and subsequent injury to the pilot or co-pilot.
