Abstract
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters. This AD was prompted by a report of broken main gearbox (MGB) right hand (RH) center and rear rail support assemblies. This AD requires repetitively inspecting the MGB RH and left hand (LH) center rail support for cracks and, depending on the results of these inspections, accomplishing corrective actions. This AD prohibits the installation of certain part-numbered MGB support assemblies unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
