## Discrepancy

(CAN) IN-FLIGHT THE MASTER CAUTION THE TRANSMISSION OIL PRESSURE LIGHT ILLUMINATED AND THE TRANSMISSION OIL PRESSURE WAS RAPIDLY FALLING.  THE ACFT WAS LANDED IMMEDIATELY IN A SAFE ZONE.  UPON LANDING, OIL WAS CONFIRMED LEAKING FROM THE TRANSMISSION.  TRANSMISSION INSPECTED AND LEAKAGE FOUND FROM DEBRIS MONITOR. NOTED THAT MONITOR WAS INCORRECTLY ORIENTED AND TRANSMISSION OIL LINE BRACKET, PN 205-040-123-101 HAD CRACKED,  ALLOWING DEBRIS MONITOR TO LIFT ON STUDS.
