A non-scientific review of NTSB records for a few years done moments ago
by me looking for C152 AND "rudder" shows no cases of rudder failure or
cracking of the rudder structure/attach points in any of the accident
synopses.
Doubt that even if the rudder fell off a 152 it would cause an accident.
Most 152 pilots don't do anything with those pedals other than taxi.
