## Discrepancy

(CAN) IFSD/LOSS OF OIL ENGINE EXPERIENCED OIL PRESSURE FLUCTUATIONS IN FLIGHT AND WAS SHUT DOWN PRIOR TO THE CCAS WARNING SYSTEM ACTIVATION.  THE LIGHT ON THE OIL PRESSURE GAUGE WAS INDICATING LOW PRESSURE AT THE TIME OF SHUT DOWN.  PILOT REPORT REVEALED THAT THE MOP HAD REMAINED ABOVE 40 PSID.  CAUSE OF LOW OIL PRESSURE WAS ATTRIBUTED TO THE LOSS OF 4 LITERS OF OIL DUE TO A LEAK AT THE AC GENERATOR SEAL.
