Narrative:

At cruise I noticed the left oil pressure gauge fluctuating. Looking at all other engine parameters, it appeared that the gauge was malfunctioning. We discussed the indication and referred to the checklist and MEL for information. Within 5-10 mins, we noticed an intermittent light capsule flash on the master caution panel. The #1 engine oil pressure light was lighting up momentarily and then extinguishing. Once we confirmed this, we agreed that the engine needed to be shut down. ATC was advised of the situation and a lower altitude was requested with priority handling. This was given immediately and an uneventful descent and approach with a landing at bos was accomplished. The emergency equipment was standing by when we landed. Engine was found to be damaged by internal means. Callback conversation with reporter revealed the following information: the reporter is flying the G-2 in a corporate operation. There has been no final report on the reason for the engine failure. The engine lost about 12 pints of oil. The oil filter was clogged with metal shavings. This was the reporter's first engine shutdown and he hopes that it will be the last.

Title: INFLT ENG SHUTDOWN.

Narrative: AT CRUISE I NOTICED THE L OIL PRESSURE GAUGE FLUCTUATING. LOOKING AT ALL OTHER ENG PARAMETERS, IT APPEARED THAT THE GAUGE WAS MALFUNCTIONING. WE DISCUSSED THE INDICATION AND REFERRED TO THE CHKLIST AND MEL FOR INFO. WITHIN 5-10 MINS, WE NOTICED AN INTERMITTENT LIGHT CAPSULE FLASH ON THE MASTER CAUTION PANEL. THE #1 ENG OIL PRESSURE LIGHT WAS LIGHTING UP MOMENTARILY AND THEN EXTINGUISHING. ONCE WE CONFIRMED THIS, WE AGREED THAT THE ENG NEEDED TO BE SHUT DOWN. ATC WAS ADVISED OF THE SIT AND A LOWER ALT WAS REQUESTED WITH PRIORITY HANDLING. THIS WAS GIVEN IMMEDIATELY AND AN UNEVENTFUL DSCNT AND APCH WITH A LNDG AT BOS WAS ACCOMPLISHED. THE EMER EQUIP WAS STANDING BY WHEN WE LANDED. ENG WAS FOUND TO BE DAMAGED BY INTERNAL MEANS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR IS FLYING THE G-2 IN A CORPORATE OP. THERE HAS BEEN NO FINAL RPT ON THE REASON FOR THE ENG FAILURE. THE ENG LOST ABOUT 12 PINTS OF OIL. THE OIL FILTER WAS CLOGGED WITH METAL SHAVINGS. THIS WAS THE RPTR'S FIRST ENG SHUTDOWN AND HE HOPES THAT IT WILL BE THE LAST.
