morrisman68,
Welcome into the great Brotherhood of PPRuNe !
Not commonplace, although every aircraft varies slightly, and there are known "rogues", but not so many now as in earlier years.
Was a story (for which I cannot vouch) that a Varsity was once "snagged" for strange trim problems.
Investigation revealed that the fin/rudder assembly was several degrees off vertical, more digging disclosed that it had been (illicitly) barrel-rolled by some miscreant who had kept quiet about it.
