## Discrepancy

DURING CLIMB, CREW COULD NOT ENGAGE AUTOPILOT. DURING HAND FLYING, CREW GOT SEVERAL UNCOMMANDED GO-AROUND COMMANDS IN WHICH  COMMAND BARS WOULD POP-UP AND THROTTLES WOULD ADVANCE TO FULL POWER.  MX FOUND THE BODY OF GO-AROUND SWITCH HAD SEPARATED WHICH CAUSED SWITCH TO RECESS A BIT INTO THE YOKE. BECAUSE SWITCH POSTS DID NOT HAVE HEAT SHRINK ON THEM, THEY WERE SHORTING OUT CAUSING THE UNCOMMANDED GO-AROUND SCENERIO. MX ENSURED SHRINK TUBE WAS INSTALLED ON NEW SWITCH.
