## Discrepancy

FUEL BYPASS WARNING DURING CLIMB, PILOT RECEIVED A FUEL IMPENDING BYPASS WARNING ON THE RT ENGINE FOLLOWED SHORTLY AFTER BY A SIMILAR WARNING ON THE LT ENGINE.  EMERGENCY WAS DECLARED AND THE ACFT RETURNED TO THE POINT OF DEPARTURE FOR AN UNEVENTFUL LANDING WITH ENGINES OPERATING NORMALLY.  THIS ACFT HAS HAD A RECENT HISTORY OF TRIGGERING FUEL BYPASS WARNINGS FOR WHICH NO FAULTS WERE FOUND.  TROUBLESHOOTING IS ON-GOING.
