## Discrepancy

HIGH COMPRESSOR REAR HUB WAS RECEIVED WITH SB 4070 HOLES NOT PROPERLY LOCATED.  THE HUB BORE SHOULD HAVE BEEN SCALLOPED, BUT THE HOLES WERE LOCATED ON THE BALANCE FLANGE AND THE DISK WAS DRILLED COMPLETELY THROUGH.  THE OVERHAUL AGENCY WAS FENIX AVIATION CORP., MIAMI, FLORIDA 33142.
