Our aircraft had just come back from repair for an oil leak on right engine. As it was scheduled to go to europe a 1 hour test flight had been performed with no problems. We departed houston for shannon via a fuel stop in gander. Oil was checked in gander and was ok. On arrival in shannon oil was again checked and the engine that had been recently repaired required servicing. Maintenance at home base was advised and consumption was deemed within limits and after layover we proceeded with return flight. On arrival back in gander oil was again checked and right engine again required servicing. Maintenance at home base was again notified and we were released to proceed to houston, as still within limits. En route to houston we noted fluctuating oil pressure on our right engine and thrust was reduced to idle on this engine. We advised center that we had reduced thrust on 1 engine to idle due fluctuating oil pressure and requested a cruise descent from FL430. Power was maintained at idle with no problem for some time, but approaching houston we performed a precautionary shutdown of the right engine as the oil pressure deteriorated below minimums for idle thrust. The remainder of the flight was uneventful and the aircraft was delivered to maintenance on arrival houston.

Title: THE ACFT HAD JUST COME BACK FROM REPAIR FOR AN OIL LEAK ON THE R ENG. PRIOR TO GOING TO EUROPE FROM HOU PERFORMED A SATISFACTORY 1 HR TEST FLT. AT GANDER THE OIL WAS CHKED OK. AT SHANNON AND BACK AT GANDER THE R ENG NEEDED SVCING, BUT WAS WITHIN LIMITS. ENRTE TO HOU THE OIL PRESSURE FLUCTUATED AND DROPPED LOW. A PRECAUTIONARY ENG SHUTDOWN WAS ACCOMPLISHED WITH A SINGLE ENG LNDG AT HOU.
Narrative: OUR ACFT HAD JUST COME BACK FROM REPAIR FOR AN OIL LEAK ON R ENG. AS IT WAS SCHEDULED TO GO TO EUROPE A 1 HR TEST FLT HAD BEEN PERFORMED WITH NO PROBS. WE DEPARTED HOUSTON FOR SHANNON VIA A FUEL STOP IN GANDER. OIL WAS CHKED IN GANDER AND WAS OK. ON ARR IN SHANNON OIL WAS AGAIN CHKED AND THE ENG THAT HAD BEEN RECENTLY REPAIRED REQUIRED SVCING. MAINT AT HOME BASE WAS ADVISED AND CONSUMPTION WAS DEEMED WITHIN LIMITS AND AFTER LAYOVER WE PROCEEDED WITH RETURN FLT. ON ARR BACK IN GANDER OIL WAS AGAIN CHKED AND R ENG AGAIN REQUIRED SVCING. MAINT AT HOME BASE WAS AGAIN NOTIFIED AND WE WERE RELEASED TO PROCEED TO HOUSTON, AS STILL WITHIN LIMITS. ENRTE TO HOUSTON WE NOTED FLUCTUATING OIL PRESSURE ON OUR R ENG AND THRUST WAS REDUCED TO IDLE ON THIS ENG. WE ADVISED CTR THAT WE HAD REDUCED THRUST ON 1 ENG TO IDLE DUE FLUCTUATING OIL PRESSURE AND REQUESTED A CRUISE DSCNT FROM FL430. PWR WAS MAINTAINED AT IDLE WITH NO PROB FOR SOME TIME, BUT APCHING HOUSTON WE PERFORMED A PRECAUTIONARY SHUTDOWN OF THE R ENG AS THE OIL PRESSURE DETERIORATED BELOW MINIMUMS FOR IDLE THRUST. THE REMAINDER OF THE FLT WAS UNEVENTFUL AND THE ACFT WAS DELIVERED TO MAINT ON ARR HOUSTON.
