## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Bell Helicopter Textron Canada Limited (Bell) Model 505 helicopters. This AD requires inspecting each swashplate assembly bearing (bearing), and depending on the inspection results, removing the bearing from service. This AD was prompted by a report of a bearing that migrated out of the swashplate inner ring. The actions of this AD are intended to address an unsafe condition on these products.
