## Discrepancy

THE ACFT WAS RETURNING TO BASE, WAS ON FINAL APPROACH, WHEN THE PILOT AND MED CREW ON BOARD ALL SMELLED AN ODOR THAT WAS INITIALLY THOUGHT TO BE THE AIR CONDITIONING COMPRESSOR BELT HAD BURNED.  THE ACFT LANDED AND SHUTDOWN WITHOUT FURTHER INCIDENT.  THE MECHANIC TROUBLESHOT THE SYS AND FOUND THAT THE FWD EVAPORATOR BLOWER MOTOR HAD SHORTED.  THE MECHANIC PLACED A NEW BLOWER MOTOR ON ORDER AND MEL'D THE AIR CONDITIONING SYS TO RETURN THE ACFT TO SERVICE. NOTE:  THE ENGINE TOTAL CYCLES IS NP.  NG TOTAL CYCLES IS 9488.1
