## Discrepancy

(CAN) UPON COMPLIANCE OF THE FUEL QTY INDICATORS PERFORMANCE TEST (ANNUAL ITEM), IT WAS NOTED THAT THE LT WING TRANSMITTER DID NOT GO QUITE TO ZERO.  (INDICATED SLIGHTLY ABOVE THE '0' READING ON THE GAUGE)  FURTHER INSPECTION REVEALED THAT THE TRANSMITTER ARM WAS RESTING ON A STRINGER INSIDE THE TANK.  IT WAS DETERMINED THAT THE TRANSMITTER  INSTALLED IN THE LT WING WAS THE CORRECT PART NUMBER FOR THE RT WING.  INSTALLED THE CORRECT SENDING UNIT, SYSTEM FUNCTIONS NORMALLY.  THIS AIRCRAFT WAS DELIVERED FROM THE FACTORY WITH THIS INSTALLATION.
