## Discrepancy

WHILE DESCENDING THROUGH FL 330, THE AUTOPILOT DISENGAGED AND EXPERIENCED A VIOLENT PITCH UP, FOLLOWED BY A MULTITUDE OF CAS MESSAGE SUCH AS "FW COMP FAIL" BEGAN RUNNING CHECKLIST, ALL MSG'S WENT AWAY.  THE REMAINDER OF THE FLIGHT WAS UN-EVENTFUL.  THE AUTOPILOT SYSTEM OPERATIONALLY CHECKS NORMAL AT THIS TIME AND IS OKAY FOR RETURN TO SERVICE IN ACCORDANCE WITH THE CESSNA 750 MAINTENANCE MANUAL CHAPTER 22-10-02.
