## Discrepancy

(AUS) DURING FLIGHT, THE RT ENGINE GAUGE DISPLAYED LOW OIL PRESSURE.  ENGINE GROUND RUN WITH A CALIBRATED OIL PRESSURE GAUGE PLUMBED INTO SYSTEM WAS CARRIED OUT WITH NO FAULT FOUND.  SUSPECTING IT COULD HAVE BEEN A SLUDGE PROBLEM IN THE PRESSURE LINE BETWEEN THE GAUGE AND ENGINE, THE LINE WAS PURGED AND REFILLED WITH CLEAN OIL.
