Narrative:
Information at ilg clear and 3 mi visibility, haze, winds 2205. We were cleared to land from a visibility on runway 19. We were the only traffic that ilg tower was reporting. Upon completion of a normal landing, we were cleared to roll to the end to a 45 degree taxiway at the end of runway 19. Since it was a 45 degree exit, our speed was somewhat higher than it would have been on a 90 degree exit. At this point, I saw a very dim light ahead on the taxiway. I asked the flying pilot to stop, which he did abruptly. We determined that it was an aircraft with no lights on at all. The engine was running. When we questioned tower about the traffic, he assured us that he had none. We informed tower that it was an aircraft. At this point, the aircraft taxied off the taxiway into the grass. Tower asked us if we could get the numbers. I believe that the numbers were XXXX, an small aircraft (blue over blue). We taxied back to our hangar and I called the tower over the landline. They said that the small aircraft had landed on runway 27 west/O any radio contact or lights, and they had not even seen them land. They questioned the pilot and he stated that he had been out flying at night and had had a complete electrical failure. He had decided to return to ilg and land. How can we be responsible for visibility sep with a stealth target out there? There are numerous uncontrolled airports in the area. I feel that it would have been a much safer idea to land at the nearest uncontrolled airport until he had his electrical problem (if that was really what his problem was) corrected. Why wouldn't he have battery power available for lights and radio for a limited amount of time?

Title: CRITICAL GND CONFLICT BETWEEN CPR-MDT AND GA-SMA AT ILG. SMA HAD LANDED AT NIGHT WITH COMPLETE ELECTRICAL FAILURE UNDETECTED BY ILG TWR.
Narrative: INFO AT ILG CLR AND 3 MI VISIBILITY, HAZE, WINDS 2205. WE WERE CLRED TO LAND FROM A VIS ON RWY 19. WE WERE THE ONLY TFC THAT ILG TWR WAS RPTING. UPON COMPLETION OF A NORMAL LNDG, WE WERE CLRED TO ROLL TO THE END TO A 45 DEG TXWY AT THE END OF RWY 19. SINCE IT WAS A 45 DEG EXIT, OUR SPD WAS SOMEWHAT HIGHER THAN IT WOULD HAVE BEEN ON A 90 DEG EXIT. AT THIS POINT, I SAW A VERY DIM LIGHT AHEAD ON THE TXWY. I ASKED THE FLYING PLT TO STOP, WHICH HE DID ABRUPTLY. WE DETERMINED THAT IT WAS AN ACFT WITH NO LIGHTS ON AT ALL. THE ENG WAS RUNNING. WHEN WE QUESTIONED TWR ABOUT THE TFC, HE ASSURED US THAT HE HAD NONE. WE INFORMED TWR THAT IT WAS AN ACFT. AT THIS POINT, THE ACFT TAXIED OFF THE TXWY INTO THE GRASS. TWR ASKED US IF WE COULD GET THE NUMBERS. I BELIEVE THAT THE NUMBERS WERE XXXX, AN SMA (BLUE OVER BLUE). WE TAXIED BACK TO OUR HANGAR AND I CALLED THE TWR OVER THE LANDLINE. THEY SAID THAT THE SMA HAD LANDED ON RWY 27 W/O ANY RADIO CONTACT OR LIGHTS, AND THEY HAD NOT EVEN SEEN THEM LAND. THEY QUESTIONED THE PLT AND HE STATED THAT HE HAD BEEN OUT FLYING AT NIGHT AND HAD HAD A COMPLETE ELECTRICAL FAILURE. HE HAD DECIDED TO RETURN TO ILG AND LAND. HOW CAN WE BE RESPONSIBLE FOR VIS SEP WITH A STEALTH TARGET OUT THERE? THERE ARE NUMEROUS UNCONTROLLED ARPTS IN THE AREA. I FEEL THAT IT WOULD HAVE BEEN A MUCH SAFER IDEA TO LAND AT THE NEAREST UNCONTROLLED ARPT UNTIL HE HAD HIS ELECTRICAL PROB (IF THAT WAS REALLY WHAT HIS PROB WAS) CORRECTED. WHY WOULDN'T HE HAVE BATTERY PWR AVAILABLE FOR LIGHTS AND RADIO FOR A LIMITED AMOUNT OF TIME?
