Final rule; request for comments.
Summary
The FAA is adopting a new airworthiness directive (AD) for all helicopters with certain Pacific Scientific Company rotary buckle assemblies (buckles) installed. This AD was prompted by a report of a manufacturing defect in the screws used inside the buckle. This AD requires inspecting the buckle screws and, depending on the results, reidentifying the buckle, replacing the screws and reidentifying the buckle, or replacing the buckle. This AD also prohibits installing certain buckles. The FAA is issuing this AD to address the unsafe condition on these products.
