## Discrepancy

THE PILOT REPORTED AN OIL LEAK AND FLUCTUATING OIL PRESSURE ON THE RIGHT ENGINE.  MAINTENANCE FOUND THE ENGINE 4 QTS LOW ON OIL, CLEANED ENGINE AND COWLINGS, AND SERVICED ENGINE OIL.  THE ENGINE WAS MOTORED AND A THE OIL LEAK WAS LOCATED ON THE .125 INCH STAINLESS STEEL LINE FROM THE GOVERNOR TO THE PROP PITCH CONTROL.  THE LINE WAS CRACKED AROUND THE CIRCUMFERENCE AT THE BASE OF THE FLARE.  THE LINE WAS REPLACED WITH A SERVICEABLE LINE AND ENGINE WAS RUN UP, LEAK CHECKED AND RETURNED TO SERVICE.  THE STAINLESS 1/8 INCH LINE IS SHORT AND ACCESS TO IT IS LIMITED.  IF THE GOVERNOR AND PROP PITCH CONTROL FITTINGS ARE NOT PROPERLY ALIGNED IT IS POSSIBLE TO PRE-LOAD IT MAKING IT SUSCEPTIBLE TO A STRESS FRACTURE.
