I do not agree that 'all' ripcord assemblies built in the US are tested. The test req'ment being discussed is a design/first article test for application for a TSO-authorization.
IMO (as a holder of 6 TSO's), there is no FAA req'ment to continue with any testing once the TSO-authorization is granted.
I think too many users feel that all of their equipment is being tested regularly.
Now, having said that, I also think that it would be foolish to not to continue to do random testing of items in/after production.
Thoughts??????
