The scope has expanded slightly to include the PA-32S-300 model which was not covered in the original.

It requires owners and operators to inspect or replace certain engine air filters made by Puralator/FACET because of a manufacturing defect that could cause the filter to crack and break apart. The defective filters were made between January 1997 and September 1998. Aircraft owners must either inspect the filter within 25 flight hours or at the next scheduled inspection (whichever comes first), and then re-inspect every 25 flight hours thereafter. Alternatively, they can replace the defective filter with an approved one—if they use a different brand/model, that permanently satisfies the requirement (\"terminating action\"). Spare filters must be checked before being installed. This version adds one more aircraft model (PA-32S-300) and clarifies that switching to a different filter model ends the ongoing inspection requirement."},"flash_summary":{"complexity_score":4,"scope_assessment":{"changed":true,"description":"This amendment expands scope by adding the PA‑32S‑300 model to the list of affected aircraft and by specifying a terminating action (replacement with an approved non‑FACET filter).
