Abstract
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.A. Model AW189 helicopters. This AD was prompted by a report of a fire occurring during the operational check of the engine anti-icing system. This AD requires inspecting and measuring the resistance of the air intake electrical connectors, inspecting the bonding strap, reporting the results of the inspections, and depending on the results of the inspection, accomplishing corrective actions. This AD also prohibits the installation of an air intake controller unless certain actions are accomplished. The FAA is issuing this AD to address the unsafe condition on these products.
