## Discrepancy

DURING RUN-UP CHECK, BOTH NR 1 AND NR 2 ENGINE FUEL PRESSURE LIGHT ILLUMINATED.  WHEN THROTTLES WERE ADVANCED FROM IDLE AND AIRCRAFT WAS BROUGHT TO A HOVER DURING HOVER TURN BOTH NR 1 AND NR 2 FUEL PRESSURE LIGHTS FLICKED AND STAYED ON.  THE MECHANIC REMOVED AND REPLACED BOTH NR 1 AND NR 2 FUEL PRESSURE SWITCHES AND AIRCRAFT WAS RETURNED TO SERVICE.
