## Discrepancy

RIGHT FUEL QUANTITY INDICATOR DROPPED IN EXCESS OF NORMAL FUEL BURN AFTER TAKEOFF.  FLIGHT WAS RETURNED TO OKC AND LANDED WITHOUT INCIDENT.  MAINTENANCE VERIFIED STICK READINGS WITH FUEL QUANTITY INDICATORS.  NO DISCREPANCIES WERE NOTED.  IT IS SUSPECTED THAT THE RIGHT FUEL CLIMB VENT VALVE WAS STUCK OPEN DURING CLIMB.  AIRCRAFT WAS REFUELED TO PROPER LEVELS AND RETURNED TO SERVICE.
