## Discrepancy

ON FINAL APPROACH, THE COPILOT NOTICED AN ACRID ODOR IN THE COCKPIT.  MOMENTS LATER, THE PILOT NOTICED THE SAME SMELL.  THEY IMMEDIATELY LANDED AND EXITED THE ACFT AND NOTICED THAT THE ODOR WAS ISOLATED TO THE ACFT.  THE ACFT WAS THEN SHUTDOWN, AND A MECHANIC WAS CALLED.  THE MECHANIC THOROUGHLY INSPECTED THE ACFT, AND COULD NOT FIND THE SOURCE OF THE SMELL.  THE PILOT THEN CONDUCTED A GROUND RUN WITH THE MECHANIC IN THE COCKPIT, AND THE ODOR COULD NOT BE DUPLICATED.   RETURNED ACFT TO SERVICE.
