Action
Final rule.
Summary
The FAA is adopting a new airworthiness directive (AD) for certain Pacific Scientific Company rotary buckle assemblies (buckles). This AD requires inspecting each buckle including its buckle handle vane, and depending on the results, removing the buckle from service and installing an airworthy buckle. This AD also prohibits installing the affected buckles. This AD was prompted by several reports of cracked buckle handles. The actions of this AD are intended to address an unsafe condition on these products.
