Narrative:

I was the captain of a scheduled far part 121 flight from jfk to ric. We were cruising at 16000 ft approximately 20 mi northeast of pxt VOR, when I noticed the right engine oil pressure gauge fluctuating down to 0 psi. I called for the low oil pressure checklist. As my first officer was going through it, and about 30-60 seconds after I first noticed the pressure drop, a red light on the caption panel 'right oil pressure' illuminated. I executed the memory items for in-flight engine shutdown followed by the checklist. Emergency was declared with ZDC. I decided to land at nhk (patuxent river navy airport). On initial contact with nhk we got the current WX, runways, fire and rescue information. I decided to continue with a visual approach to runway 24 and we asked for the fire trucks to stand by. Our flight attendant was contacted and advised of the situation. She informed us the acm, who is a pilot, offered his help if needed. Since we had finished all the required tasks and still had time during the descent, we notified our company of the situation and our intentions. The landing was uneventful. The passenger were bussed to ric. Company mechanics determined the oil loss was due to a bad oil pressure transducer and replaced it. We flew the airplane to jfk via dca the following day. At our company I am aware of 3-4 in-flight shutdowns in the BAE4100 due to oil loss. Callback conversation with reporter revealed the following information: reporter stated that he had made a postflt inspection of the aircraft revealing a loss of the oil in the right engine. He further stated that maintenance remarked that they must have received a bad batch of oil pressure transducers since there had been other incidents of in-flight engine shutdowns due to engine loss of oil. In fact, the reporter said that the same engine was shut down by another captain during approach for the same reason within 2 days after the oil transducer had been replaced after his flight.

Title: FLC OF A BAE4100 JETSTREAM BA41, SHUT DOWN THE R ENG DURING CRUISE DUE TO LOSS OF OIL PRESSURE AND DIVERTED TO LAND. POSTFLT INSPECTION DISCLOSED THAT ALL THE ENG OIL WAS LOST DUE TO A FAULTY OIL PRESSURE TRANSDUCER.

Narrative: I WAS THE CAPT OF A SCHEDULED FAR PART 121 FLT FROM JFK TO RIC. WE WERE CRUISING AT 16000 FT APPROX 20 MI NE OF PXT VOR, WHEN I NOTICED THE R ENG OIL PRESSURE GAUGE FLUCTUATING DOWN TO 0 PSI. I CALLED FOR THE LOW OIL PRESSURE CHKLIST. AS MY FO WAS GOING THROUGH IT, AND ABOUT 30-60 SECONDS AFTER I FIRST NOTICED THE PRESSURE DROP, A RED LIGHT ON THE CAPTION PANEL 'R OIL PRESSURE' ILLUMINATED. I EXECUTED THE MEMORY ITEMS FOR INFLT ENG SHUTDOWN FOLLOWED BY THE CHKLIST. EMER WAS DECLARED WITH ZDC. I DECIDED TO LAND AT NHK (PATUXENT RIVER NAVY ARPT). ON INITIAL CONTACT WITH NHK WE GOT THE CURRENT WX, RWYS, FIRE AND RESCUE INFO. I DECIDED TO CONTINUE WITH A VISUAL APCH TO RWY 24 AND WE ASKED FOR THE FIRE TRUCKS TO STAND BY. OUR FLT ATTENDANT WAS CONTACTED AND ADVISED OF THE SIT. SHE INFORMED US THE ACM, WHO IS A PLT, OFFERED HIS HELP IF NEEDED. SINCE WE HAD FINISHED ALL THE REQUIRED TASKS AND STILL HAD TIME DURING THE DSCNT, WE NOTIFIED OUR COMPANY OF THE SIT AND OUR INTENTIONS. THE LNDG WAS UNEVENTFUL. THE PAX WERE BUSSED TO RIC. COMPANY MECHS DETERMINED THE OIL LOSS WAS DUE TO A BAD OIL PRESSURE TRANSDUCER AND REPLACED IT. WE FLEW THE AIRPLANE TO JFK VIA DCA THE FOLLOWING DAY. AT OUR COMPANY I AM AWARE OF 3-4 INFLT SHUTDOWNS IN THE BAE4100 DUE TO OIL LOSS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT HE HAD MADE A POSTFLT INSPECTION OF THE ACFT REVEALING A LOSS OF THE OIL IN THE R ENG. HE FURTHER STATED THAT MAINT REMARKED THAT THEY MUST HAVE RECEIVED A BAD BATCH OF OIL PRESSURE TRANSDUCERS SINCE THERE HAD BEEN OTHER INCIDENTS OF INFLT ENG SHUTDOWNS DUE TO ENG LOSS OF OIL. IN FACT, THE RPTR SAID THAT THE SAME ENG WAS SHUT DOWN BY ANOTHER CAPT DURING APCH FOR THE SAME REASON WITHIN 2 DAYS AFTER THE OIL TRANSDUCER HAD BEEN REPLACED AFTER HIS FLT.

Flight crew of a BAE4100 jetstream BA41, shut down the right engine during cruise due to loss of oil pressure and diverted to land. Postflt inspection disclosed that all the engine oil was lost due to a faulty oil pressure transducer.
