## Discrepancy

ON APPROACH, THE CREW RECEIVED A PROXI SYSTEM FAIL INDICATION AND PERFORMED A GO-AROUND.  ON THE SECOND APPROACH, THE LANDING WAS NORMAL AND FLIGHT 4009 LANDED WITH NO FURTHER INCIDENTS.  MAINTENANCE THEN INSPECTED THE PROXI SYSTEM IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 32-00-00, BUT COULD NOT DUPLICATE ANY DEFECTS.  THE AIRCRAFT WAS THEN RELEASED FOR SERVICE.
