one day just after finishing my ppl and had about 60hrs....
went on a nice long flight in a c172 that had a autopilot never seen one let alone new how it worked got in some dreadfull turb and afterwards had difficulty with the a/c ie,control problems ailerons,elevators etc....
anyway scared the **** out of myself as had no idea of what was going on nearly called a mayday anyway manage to get home without to much trouble just a little hinderance.
I found a local instructor and told him he should have a look at the a/c as it wasn't flying to good after the turb, he had a look around and came back to tell me that I had done 1.5hrs with the autopilot on!
Somehow I had bumped it? We all learn!!
