Narrative:

On feb/xx/95 while on final approach to runway 18 at sky harbor airport las vegas, nv. At approximately XB30 hours all members on board heard a radio transmission 'that was close small transport X.' all members on board scanned for traffic and no contact was made. The only traffic noted was a trainer taxiing off runway 18. The PF and instructor pilot, elected to make a go around. During the go around, all members on board scanned for the phantom aircraft without contact until reaching the departure end of the runway when the chief pilot seated in seat #4 of our C402B and I observed from behind at our 5 O'clock an aircraft higher than us turning right crosswind. No further xmissions were heard from the phantom aircraft. The training session continued without incident. All the appropriate radio calls were made during right closed traffic to runway 18 during the entire flight. It is our belief that the other aircraft was either experiencing radio problems or tuned to the wrong frequency before entering the pattern from the north where practice approachs are often conducted at a nearby airport known as las mccarran.
