## Discrepancy

DURING FLIGHT, THE CREW REPORTED THAT THE THRUST RATING BUTTON WAS STUCK AND WERE UNABLE TO CHANGE IT FROM CLIMB MODE. THE CREW DIVERTED TO MKE AND LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE THRUST RATING CONTROL BUTTON ON THE THRUST PANEL MODULE ASSEMBLY TO BE DIRTY.  THE BUTTON WAS CLEANED AND OPERATIONAL CHECKS OF THE THRUST RATING BUTTON WERE GOOD WITH NO FURTHER DEFECTS NOTED.
