## Discrepancy

NR 1 ENG OIL PRESSURE LOSS, RTFL.  OIL LOSS APPEARS TO BE RELATED TO THE FAILURE OF THE OIL FILTER HOUSING.  THIS IS A NEW FAILURE CONDITION, AND SFOEP IS REQUESTING THAT ANY AND ALL PARTS REMOVED THAT ARE RELATED TO THE CORRECTION OF THE PROBLEM BE ROUTED TO THE SAMC-EMC DESK IN THE OCC.  PLEASE INCLUDE THE MAIN OIL FILTER, WITH ANY SEALS, PARTS ETC.  REPLACED NR 1 ENGINE OIL FILTER HOUSING.
