PPL Loss of Control Training. I assume you mean the aircraft, some pilots Ive flown with seem to have loss of control as soon as they leave the crew room!
We do, apart from the obvious loss of control/stall avoidance and recovery:
Flaps full circuit and landing
Elevator jammed circuit
Wake turbulence recovery
Throttle jammed open circuit and landing
Windshear recovery
Door opening on lift off (only results in loss of control when the pilot trys to close it usually)
In the airlines apart from stall recovery training I remember doing Dutch Roll recovery and Windshear recovery with windshear being the most useful
