Narrative:
Preflight was normal with engine oil levels in the normal ranges. From the cockpit, the takeoff appeared normal, however, personnel in the hangar next to the runway reported hearing a sound like 'a playing card against bicycle spokes.' about 15 mins into the flight, while climbing through 16000 ft, we heard an aural 'oil' warning. We were unable to maintain the oil pressure/nh within acceptable limits, so the decision was made to shut down the engine. I flew the airplane and handled communication while the captain ran the checklists. An emergency was declared and we diverted to dayton. The landing was uneventful. This emergency was handled exactly as we were trained in ground and simulator. Our reaction was instinctive and without excessive excitement. I also feel that excellent CRM training made this event a 'non event.' it was determined an oil line had ruptured, dumping 14 quarts (non-pre flightable item).

Title: FLC OF AN LTT DIVERTED TO LAND WHEN ONE OF THE ENGS LOST OIL PRESSURE AND THE ENG WAS SHUT DOWN. THE MALFUNCTION WAS CAUSED BY A BROKEN ENG OIL LINE. DIVERSION TO ALTERNATE.
Narrative: PREFLT WAS NORMAL WITH ENG OIL LEVELS IN THE NORMAL RANGES. FROM THE COCKPIT, THE TKOF APPEARED NORMAL, HOWEVER, PERSONNEL IN THE HANGAR NEXT TO THE RWY RPTED HEARING A SOUND LIKE 'A PLAYING CARD AGAINST BICYCLE SPOKES.' ABOUT 15 MINS INTO THE FLT, WHILE CLBING THROUGH 16000 FT, WE HEARD AN AURAL 'OIL' WARNING. WE WERE UNABLE TO MAINTAIN THE OIL PRESSURE/NH WITHIN ACCEPTABLE LIMITS, SO THE DECISION WAS MADE TO SHUT DOWN THE ENG. I FLEW THE AIRPLANE AND HANDLED COM WHILE THE CAPT RAN THE CHKLISTS. AN EMER WAS DECLARED AND WE DIVERTED TO DAYTON. THE LNDG WAS UNEVENTFUL. THIS EMER WAS HANDLED EXACTLY AS WE WERE TRAINED IN GND AND SIMULATOR. OUR REACTION WAS INSTINCTIVE AND WITHOUT EXCESSIVE EXCITEMENT. I ALSO FEEL THAT EXCELLENT CRM TRAINING MADE THIS EVENT A 'NON EVENT.' IT WAS DETERMINED AN OIL LINE HAD RUPTURED, DUMPING 14 QUARTS (NON-PRE FLIGHTABLE ITEM).
