What was found
(CAN) DURING FLIGHT, THE CREW NOTICED THAT THE RT FUEL QUANTITY GAUGE HAD DROPPED TO ZERO. THE LOW LEVEL LIGHT DID NOT ILLUMINATE, ASSURING THE CREW THAT THIS WAS AN INDICATION PROBLEM ONLY. THE RT QUANTITY AMPLIFIER WAS REPLACED AND THE SYSTEM WAS PROPERLY CALIBRATED PRIOR TO THIS FLIGHT. THE RECENTLY REPLACED AMPLIFIER WAS FOUND TO HAVE FAILED INTERNALLY.
