Narrative:

During taxi for takeoff, I noticed a low oil pressure indication from my left engine. The pressure was not low enough to warrant engine shutdown yet, but continued to lower and I received a low oil pressure warning light. I then decided to shut the engine down by the feather lever. During the shutdown and shortly after, I noticed an abundant amount of smoke coming from my left engine in extreme amounts. The smoke did not subside or lessen after shutdown, in fact, it began to increase in amount and rate shortly after shutdown. I told the first officer that we're going to go ahead and evacuate/evacuation as a precaution due to the continuing smoke. No flames were seen and I had no fire warning. I instructed him to evacuate/evacuation left through the main cabin door and inform the passenger accordingly. I proceeded to secure the aircraft and communication with ATC -- tower. Tower asked me if I wanted crash/fire/rescue equipment and I stated 'yes, go ahead and send crash/fire/rescue.' I then followed the passenger out of the aircraft giving explanations along the way to passenger. I gathered the passenger in a secure area, taking into account the possible fire hazard and airport security. I told my first officer to watch the passenger and take care of their needs while I coordinated with crash/fire/rescue. I coordinated with crash/fire/rescue, and our company maintenance until all was secure. The crash/fire/rescue commented on our procedure as being correct and good. I then proceeded to take care of our passenger needs. The crash/fire/rescue gave us a ride to our operations. He asked me for no information. It was a precautionary evacuate/evacuation and no emergency was declared. There were no injuries, and I feel that no FARS or company procedures were violated. The plane was just written up for an oil leak left engine just prior to me taking it. Company maintenance often doesn't regard oil leaks as serious, and signs them off carelessly (in my opinion). Company mechanics taxied the aircraft away before I had a chance to make a maintenance log entry. However, they made a log entry themselves, which was not thorough (in my opinion). I then coordinated via telephone with my company.

Title: CAPT OF AN LTT ACR ACFT EVACED THE PAX ON THE TXWY WHILE TAXIING FOR TKOF DUE TO HVY SMOKE FROM 1 ENG.

Narrative: DURING TAXI FOR TKOF, I NOTICED A LOW OIL PRESSURE INDICATION FROM MY L ENG. THE PRESSURE WAS NOT LOW ENOUGH TO WARRANT ENG SHUTDOWN YET, BUT CONTINUED TO LOWER AND I RECEIVED A LOW OIL PRESSURE WARNING LIGHT. I THEN DECIDED TO SHUT THE ENG DOWN BY THE FEATHER LEVER. DURING THE SHUTDOWN AND SHORTLY AFTER, I NOTICED AN ABUNDANT AMOUNT OF SMOKE COMING FROM MY L ENG IN EXTREME AMOUNTS. THE SMOKE DID NOT SUBSIDE OR LESSEN AFTER SHUTDOWN, IN FACT, IT BEGAN TO INCREASE IN AMOUNT AND RATE SHORTLY AFTER SHUTDOWN. I TOLD THE FO THAT WE'RE GOING TO GO AHEAD AND EVAC AS A PRECAUTION DUE TO THE CONTINUING SMOKE. NO FLAMES WERE SEEN AND I HAD NO FIRE WARNING. I INSTRUCTED HIM TO EVAC L THROUGH THE MAIN CABIN DOOR AND INFORM THE PAX ACCORDINGLY. I PROCEEDED TO SECURE THE ACFT AND COM WITH ATC -- TWR. TWR ASKED ME IF I WANTED CRASH/FIRE/RESCUE EQUIP AND I STATED 'YES, GO AHEAD AND SEND CRASH/FIRE/RESCUE.' I THEN FOLLOWED THE PAX OUT OF THE ACFT GIVING EXPLANATIONS ALONG THE WAY TO PAX. I GATHERED THE PAX IN A SECURE AREA, TAKING INTO ACCOUNT THE POSSIBLE FIRE HAZARD AND ARPT SECURITY. I TOLD MY FO TO WATCH THE PAX AND TAKE CARE OF THEIR NEEDS WHILE I COORDINATED WITH CRASH/FIRE/RESCUE. I COORDINATED WITH CRASH/FIRE/RESCUE, AND OUR COMPANY MAINT UNTIL ALL WAS SECURE. THE CRASH/FIRE/RESCUE COMMENTED ON OUR PROC AS BEING CORRECT AND GOOD. I THEN PROCEEDED TO TAKE CARE OF OUR PAX NEEDS. THE CRASH/FIRE/RESCUE GAVE US A RIDE TO OUR OPS. HE ASKED ME FOR NO INFO. IT WAS A PRECAUTIONARY EVAC AND NO EMER WAS DECLARED. THERE WERE NO INJURIES, AND I FEEL THAT NO FARS OR COMPANY PROCS WERE VIOLATED. THE PLANE WAS JUST WRITTEN UP FOR AN OIL LEAK L ENG JUST PRIOR TO ME TAKING IT. COMPANY MAINT OFTEN DOESN'T REGARD OIL LEAKS AS SERIOUS, AND SIGNS THEM OFF CARELESSLY (IN MY OPINION). COMPANY MECHS TAXIED THE ACFT AWAY BEFORE I HAD A CHANCE TO MAKE A MAINT LOG ENTRY. HOWEVER, THEY MADE A LOG ENTRY THEMSELVES, WHICH WAS NOT THOROUGH (IN MY OPINION). I THEN COORDINATED VIA TELEPHONE WITH MY COMPANY.
