Presumably Collins have a list of all affected Serial/Part No's. How many others depends on the number of replacements in the field. One would suspect probably not that many (assuming it has a low failure rate) but it should be fairly simple to work that out. For a while I ran a team (Military) where we often got asked to locate specific items (ie given Serial/Part no(s)) fitted or in stock. Usually the longest part of the process was boiling the kettle for a coffee ahead of the asset database search. True, it depends on the airlines at the end of the day knowing what work they have done since they took delivery.
AFAIK, the FAA has not yet determined whether the relevant actuators need to be swapped out.
