It IS an AD in Canada, for those Canadians lurking here. A Canadian
150 went down around three years ago, with the rudder stop locked over
the stop bolt head during a training spin. The rudder hinge bushings
as well as the stops were all shot and the stop was able to travel far
enough to catch behind the bolt head and lock the rudder at full
deflection. I believe the bellcrank was a bit loose, too.
The new stops are much larger and the stop bolt has a much larger
head on it.

btw, there is much more to the story than this, involving such things as
a rudder return spring removed from the airplane and then being put back
into service when it should have been grounded, etc.
