Airworthiness Directives; Pacific Scientific Company Seat Restraint System Rotary Buckle Assemblies

FAA / Federal Register · 2020-20624

The FAA is reopening the comment period for an earlier proposed rulemaking (NPRM) for certain Pacific Scientific Aviation Services seat restraint rotary buckle assemblies (buckles). The NPRM proposed to require inspecting each buckle and buckle handle vane, and depending on the inspection results, removing the buckle from service and installing an airworthy buckle. The NPRM also proposed to prohibit the installation of the affected buckles. The NPRM was prompted by several reports of cracked buckle handles. This action reopens the comment period because a significant amount of time has elapsed since the NPRM was published. Additionally, this action clarifies the applicability and updates nomenclature, contact information, and the design approval holder's (DAH) name.
