Narrative:

The problem occurred at the union of the oil line leading from the engine to the oil cooler (inboard left side) discovered through warning system installed on the be-02. Possible fault may be in too much wrenching on the halt for the union. Increased awareness on behalf of mechanics may have found problem earlier. All appropriate actions were taken in a timely manner. A flight captained by myself experienced an emergency en route from casper, wy, to denver, co. The flight had progressed approximately 45 mins en route when a master warning flasher illuminated aboard the be-02. An annunciator labeled oil pressure associated with the warning flasher began to illuminate intermittently. At this point the crew noticed an 80 psi oil pressure reading on the left engine. After power had been reduced initially and oil pressure continued to drop below normal operating levels, it was evident the engine would have to be shut down and this occurred at an oil pressure reading of 50 psi. Upon executing all applicable emergency checklists, ATC was notified and flight proceeded directly to den airport and a landing without incident was achieved. Once the flight was completed, the company, FAA and NTSB were contacted by myself and company in that order.

Title: LTT ENG SHUTDOWN DURING HIGH ALT CRUISE.

Narrative: THE PROB OCCURRED AT THE UNION OF THE OIL LINE LEADING FROM THE ENG TO THE OIL COOLER (INBOARD L SIDE) DISCOVERED THROUGH WARNING SYS INSTALLED ON THE BE-02. POSSIBLE FAULT MAY BE IN TOO MUCH WRENCHING ON THE HALT FOR THE UNION. INCREASED AWARENESS ON BEHALF OF MECHS MAY HAVE FOUND PROB EARLIER. ALL APPROPRIATE ACTIONS WERE TAKEN IN A TIMELY MANNER. A FLT CAPTAINED BY MYSELF EXPERIENCED AN EMER ENRTE FROM CASPER, WY, TO DENVER, CO. THE FLT HAD PROGRESSED APPROX 45 MINS ENRTE WHEN A MASTER WARNING FLASHER ILLUMINATED ABOARD THE BE-02. AN ANNUNCIATOR LABELED OIL PRESSURE ASSOCIATED WITH THE WARNING FLASHER BEGAN TO ILLUMINATE INTERMITTENTLY. AT THIS POINT THE CREW NOTICED AN 80 PSI OIL PRESSURE READING ON THE L ENG. AFTER PWR HAD BEEN REDUCED INITIALLY AND OIL PRESSURE CONTINUED TO DROP BELOW NORMAL OPERATING LEVELS, IT WAS EVIDENT THE ENG WOULD HAVE TO BE SHUT DOWN AND THIS OCCURRED AT AN OIL PRESSURE READING OF 50 PSI. UPON EXECUTING ALL APPLICABLE EMER CHKLISTS, ATC WAS NOTIFIED AND FLT PROCEEDED DIRECTLY TO DEN ARPT AND A LNDG WITHOUT INCIDENT WAS ACHIEVED. ONCE THE FLT WAS COMPLETED, THE COMPANY, FAA AND NTSB WERE CONTACTED BY MYSELF AND COMPANY IN THAT ORDER.
