## Discrepancy

THE AIRCRAFT WAS GROUNDED. LEFT FUEL TANK LOW QUANTITY INDICATION. AFTER TAKE OFF, THE FUEL INDICATION FOR THE LEFT TANK SHOWED FUEL TOTAL OF 1300 LBS. FLIGHT CREW SUSPECTED THAT THERE MAY HAVE BEEN A MAJOR FUEL LEAK. CAPTAIN SUSPECTED THAT THE FUEL INDICATION WAS FAULTY AND REQUIRED MAINTENANCE. NO EMERGENCY DECLARED. REPLACED 4W PROBES 29, 60 AND 34QT1. (PLEASE SEE SDR AALA201809219012)
