Airworthiness Directives; Bell Textron Canada Limited Helicopters

FAA / Federal Register · 2022-25404

The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 505 helicopters. This AD was prompted by the discovery of a potential fouling condition between the rotating swashplate outer ring and the non-rotating collective lever. This AD requires inspecting the collective control system rigging and depending on the results, rigging the collective and cyclic control systems, as specified in a Transport Canada emergency AD, which is incorporated by reference. This AD also requires reporting certain information. The FAA is issuing this AD to address the unsafe condition on these products.
