Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 505 helicopters. This AD was prompted by a report of a quality escape in the production installation of a washer installed on the tail rotor pitch link assembly (pitch link assembly). This AD requires a one-time visual inspection for proper installation of the washer installed on the pitch link assembly and, depending on the results of the inspection, corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
