Narrative:

We began our takeoff roll. At approximately 85 KIAS, we received a momentary master warning light and a #2 engine oil pressure warning light. These lights illuminated, then extinguished. At that point we initiated an abort. At the time of the warning lights, all engine gauges for the #2 engine indicated normal. We taxied clear of the active runway and performed a full power run-up with all engine gauges indicating normal. We taxied back for another takeoff. On climb out, at approximately 1000 ft AGL, the #2 engine oil pressure gauge began to fluctuate, but no master warning or #2 engine oil pressure warning lights illuminated. The decision was made to return to key west airport. The on-call mechanic visually inspected the #2 engine but found no problem. 3 quarts of oil were added to the engine. After being signed off by the mechanic, we completed the trip to miami and completed our schedule with that aircraft with no further problems. I feel the airline could offer more operations training to new hires and veteran employees on how to handle the aftermath of an aborted takeoff.

Title: FLC OF AN MDT TURBOPROP COMMUTER RETURNED TO LAND AFTER ONE OF THE ENG'S OIL PRESSURE WAS FLUCTUATING.

Narrative: WE BEGAN OUR TKOF ROLL. AT APPROX 85 KIAS, WE RECEIVED A MOMENTARY MASTER WARNING LIGHT AND A #2 ENG OIL PRESSURE WARNING LIGHT. THESE LIGHTS ILLUMINATED, THEN EXTINGUISHED. AT THAT POINT WE INITIATED AN ABORT. AT THE TIME OF THE WARNING LIGHTS, ALL ENG GAUGES FOR THE #2 ENG INDICATED NORMAL. WE TAXIED CLR OF THE ACTIVE RWY AND PERFORMED A FULL PWR RUN-UP WITH ALL ENG GAUGES INDICATING NORMAL. WE TAXIED BACK FOR ANOTHER TKOF. ON CLBOUT, AT APPROX 1000 FT AGL, THE #2 ENG OIL PRESSURE GAUGE BEGAN TO FLUCTUATE, BUT NO MASTER WARNING OR #2 ENG OIL PRESSURE WARNING LIGHTS ILLUMINATED. THE DECISION WAS MADE TO RETURN TO KEY WEST ARPT. THE ON-CALL MECH VISUALLY INSPECTED THE #2 ENG BUT FOUND NO PROB. 3 QUARTS OF OIL WERE ADDED TO THE ENG. AFTER BEING SIGNED OFF BY THE MECH, WE COMPLETED THE TRIP TO MIAMI AND COMPLETED OUR SCHEDULE WITH THAT ACFT WITH NO FURTHER PROBS. I FEEL THE AIRLINE COULD OFFER MORE OPS TRAINING TO NEW HIRES AND VETERAN EMPLOYEES ON HOW TO HANDLE THE AFTERMATH OF AN ABORTED TKOF.
