## Discrepancy

AFTER T/O NR 1 FUEL QTY INDICATOR BLANKED.  SOON AFTER TOTAL FOB INDICATOR BLANKED.  BOTH SOON CAME BACK BUT NR 1 TANK WAS 400 - 500 LBS LESS THAN IT HAD INDICATED PRIOR TO T/O.  AS WE LEVELED AT ATTITUDE.  NR 1 TANK INCREASED BY ABOUT 500 LBS AND INDICATES WHAT IT DID PRIOR TO T/O.  IN CRUISE APPEARS TO INDICATE NORMAL NOW.  VERIFIED NO CURRENT FAULTS.  LAST FAULT (28 41108) WAS 7 FLTS AGO NO FAULTS SINCE.  ACCOMP GROUND TEST, TEST PASS.  CHECKED FOR WATER IN NR 1 TANK NO WATER FOUND.  TRANSFERRED FUEL FROM NR 2 TO NR 1 AND BACK AGAIN.  RE-ACCOMP GROUND TEST, TEST PASS.  REF FIM 28 41 00 810 807.
