## Discrepancy

WHILE EN ROUTE, THE ACFT EXPERIENCED SMOKE IN THE COCKPIT, APPROX 20 MILES FROM DESTINATION.  THE CREW SHUTDOWN AVIONICS & DECLARED AN EMER.  THE ACFT LANDED SAFELY & WAS MET BY FIRE DEPARTMENT.  FIRE DEPARTMENT VERIFIED NO FIRE OR SMOKE EXISTS.  TROUBLESHOOTING FOUND THE COPILOT'S OR RT PRIMARY FLIGHT DISPLAY, PFD WAS CAUSE OF SMOKE.  REMOVED FAULTY PFD & INSTALLED AN OVERHAULED UNIT OF LIKE PN WHICH OPERATIONS CHECKED SATISFACTORILY.  FURTHER INVESTIGATION FOUND NO OTHER ISSUES RELATING TO SMOKE INCIDENT.  THE ACFT WAS RETURNED TO SERVICE & THE FAULTY UNIT WAS SENT FOR REPAIR.  DISPLAY UNITS ARE ON CONDITION ITEMS & MAY NEED AN OVERHAUL LIMITATION TO HELP PREVENT FUTURE INTERNAL COMPONENT FAILURES, WHICH RESULT IN SMOKE IN COCKPIT.
