## Discrepancy

WHILE THE PILOT WAS LANDING AT THE BASE, THE CREW DETECTED FUMES IN THE AIRCRAFT CREW COMPARTMENT. THE NR 2 GPS LOST POWER SHORTLY THEREAFTER. COMPLETED THE LANDING AND SHUT DOWN THE AIRCRAFT.  MECHANIC TROUBLESHOT THE PROBLEM TO AN INTERNAL SHORT OF THE DIMMING SYSTEM ON NR 2 GPS.  REPLACED WITH REPAIRED UNIT. THE AIRCRAFT WAS OPERATIONALLY CHECKED WITH NO DEFECTS NOTED, AND RETURNED TO SERVICE AT THAT TIME.
