## Discrepancy

DURING TAKEOFF FROM LANDING ZONE THE NR 1 SYS MGB OIL  PRESS DROPPED TO .4 BAR, BELOW NORMAL RANGE.  THERE WERE NO CHIPS DETECTED OR TEMP RISE ASSOCIATED WITH THIS INDICATION.  SYS NR 2 PRESS REMAINED WITHIN NORMAL LIMITS.  THE FLIGHT WAS ABORTED & CONTINUED TO THEIR BASE OF OPERATIONS, HELIPAD THAT WAS LESS THAT 1 NM AWAY.  ACCOMPLISHED MIN POWER DESCENT & LANDING & EXECUTED NORMAL SHUTDOWN WITHOUT INCIDENT.  POST FLIGHT INSPECTION DID NOT REVEAL ANY FLUID LOSS OR ABNORMALITIES EVIDENT ON THE PILOT POST FLIGHT.  TROUBLE SHOT THE PROBLEM & FOUND THAT THE TRANSMISSION OIL PRESS TRANSMITTER WAS BAD & REPLACED IT.  THE ACFT WAS THEN RETURNED TO SERVICE.
