Airworthiness Directive coverage
FAA / EASA public regulatory data
- FAAAD 2025-16-09effective Sep 22, 2025ProhibitionPN-family match
The FAA is adopting a new airworthiness directive (AD) for all airplanes 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 allows optionally prohibiting use of the seat until the actions required by this AD are accomplished. This AD also prohibits installing certain buckles on any airplane. The FAA is issuing this AD to address the unsafe condition on these products.
Directives citing this part number in the FAA / EASA regulatory corpus we have processed — not a complete historical AD list. An AD is a compliance requirement that drives scheduled work (inspections, replacements, modifications) on the fleets that carry the part; a directive naming this PN as the replacement part is install demand, not an action against it — and none of this is a prediction that the part will fail. PN-family matches expand an “all dash numbers” citation — verify dash-number applicability in the AD text.
