## Discrepancy

EN ROUTE THE OXYGEN HAD GONE DOWN AND THE CREW SUSPECTED AN OXYGEN LEAK.  THE FLIGHT DESCENDED TO 10,000 FEET AND DIVERTED TO PIT.  MAINTENANCE INSPECTED AND SERVICED THE OXYGEN IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 35-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
