## Discrepancy

THE INTEGRATES STANDBY INSTRUMENT ISI FAILED AND WAS REPLACED WITH AN INSPECTED PART.  THE INSPECTED ISI FAILED DURING NEXT FLIGHT.  UPON INQUIRING ABOUT THE INSPECTED ISI WE WERE NOTIFIED THAT IT WAS ORIGINALLY REMOVED FOR THE SAME FAILURE AND WAS NOT DUPLICATED DURING A BENCH TEST SO IT WAS RELEASED AS INSPECTED.  WE REMOVED THE INSPECTED ISI WITH A NEW ISI.  ORIGINAL DISCREPANCY HAS BEEN CORRECTED.
