Narrative:

Low oil pressure #1 engine warning lights noted, confirmed low pressure. Followed QRH, engine pressure stabilized with reduced power setting. No lights illuminated. Contacted dispatch, proceeded to eri. En route to eri oil pressure decreased and stabilized with warning lights illuminated, no shutdown required, normal VFR approach with #1 engine at idle thrust, normal landing, could not duplicate on ground. Same problem with engine #1 previous day (4 flight hours earlier). Oil pressure slow to come up on start, but stabilized at normal levels. Attributed to 5 degrees F temperature of engine oil. An approach briefing was made to include the possibility of an engine shutdown.

Title: AN ACR MDT EXPERIENCED LOW OIL PRESSURE ON ONE OF ITS ENGS.

Narrative: LOW OIL PRESSURE #1 ENG WARNING LIGHTS NOTED, CONFIRMED LOW PRESSURE. FOLLOWED QRH, ENG PRESSURE STABILIZED WITH REDUCED PWR SETTING. NO LIGHTS ILLUMINATED. CONTACTED DISPATCH, PROCEEDED TO ERI. ENRTE TO ERI OIL PRESSURE DECREASED AND STABILIZED WITH WARNING LIGHTS ILLUMINATED, NO SHUTDOWN REQUIRED, NORMAL VFR APCH WITH #1 ENG AT IDLE THRUST, NORMAL LNDG, COULD NOT DUPLICATE ON GND. SAME PROB WITH ENG #1 PREVIOUS DAY (4 FLT HRS EARLIER). OIL PRESSURE SLOW TO COME UP ON START, BUT STABILIZED AT NORMAL LEVELS. ATTRIBUTED TO 5 DEGS F TEMP OF ENG OIL. AN APCH BRIEFING WAS MADE TO INCLUDE THE POSSIBILITY OF AN ENG SHUTDOWN.
