## Abstract

We are adopting a new airworthiness directive (AD) for various Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB- BK117 and Model BO-105 helicopters. This AD requires removing the swashplate bellows (bellows) and repetitively inspecting the swashplate assembly. This AD was prompted by reports of loose and missing clamps installed on bellows. The actions of this AD are intended to detect and prevent an unsafe condition on these products.
