An interesting sidenote is that TOPCAT is the first STC in history that modifies the owner, not the airplane. Once the STC is issued, the owner can work on any 150/152 that he is an owner (or partial owner) of, even after selling the original STC'd plane.
Reread the quote, Tim!
It's a "special" STC on the
owner (kinda like an endorsement, but not)!
It's NOT an STC on the airplane the owner happens to own at the time.
