## Abstract

We are adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332L1 and Model EC225LP helicopters. This AD requires relocating the power supply circuit breaker source of one engine's multi-purpose air intake (MPAI). This AD is prompted by a report that power loss to the MPAI could open the engine air intakes, which could result in engine ice ingestion during flight in icing conditions. These actions are intended to prevent ice ingestion by both engines, which could result in complete loss of engine thrust, and possible loss of control of the helicopter.
