## Discrepancy

WHILE TROUBLESHOOTING AN EXISTING PROBLEM WITH ONE ENGINE, THE DIFFUSER TUBES WERE FOUND TO HAVE HEAVY CORROSION WITH SEVERAL HOLES CORRODED THROUGH.  SUBSEQUENT INSPECTION OF THE OTHER ENGINE RESULTED IN FINDING THE SAME PROBLEM.  BOTH ENGINES WERE REMOVED AND SENT TO THE MANUFACTURER.
