Narrative:

We were in VFR conditions approximately 15 NM northwest of 3CK, and had a visual on the airport. Reported to ATC, the field was in sight and were cleared for a visual approach. With VFR conditions we cancelled the IFR flight plan. We were advised by ATC of no other targets in the vicinity of 3CK and were able to go to advisory frequency. We had already been monitoring advisory frequency for several mins to establish other traffic and the active runway. Between 10 and 15 NM northwest of 3CK, the first officer made the first call to 3CK traffic and reported our position, altitude, and intentions (2400 ft MSL and planned to enter from crosswind to downwind runway 26). Approximately 5 NM northwest, first officer called again. On the crosswind to runway 26, I noticed a cessna departing from runway 26 and on the upwind. (I had not heard this aircraft report departing.) the upwind aircraft reported us in sight and would follow. At this time, first officer made another report 'on crosswind turning downwind.' at that time, the first officer exclaimed that a plane just went past our right wing. As I continued on downwind, I turned to look to my left, to see a beech sundowner at my 8 O'clock position and approximately 100 ft above, on a northeast heading. There was no time to make any action to further ourselves from the other aircraft. We never heard the beech make a call prior to reaching the pattern. As we continued on downwind, a call was made from, possibly, the beech, stating, 'citation on downwind at lake in the hills, you almost hit a musketeer!' first officer then called, 'turning base leg to runway 26.' after completing the call, I observed the beech, still at approximately 2500 ft MSL flying east. I could now see the landing light was on. After making the radio call for base, the assumed, beech, made another call, again stating, 'citation, I don't know if you are listening. You almost hit an aircraft in the pattern on downwind.' this call was heard, but we did not respond in order to avoid a potential dispute on the radio, and for the fact that we were established on final and were focusing on the landing. The beech appeared to transit the area to the east and did not land at 3CK, nor did it make any further radio calls. Factoring into not seeing the beech was the sun in our eyes, right at the relative position of the aircraft (southeast). Additionally, we had not heard any reports from the beech prior to our arrival in the pattern. We were also under the assumption of no other targets in the vicinity of 3CK. TCASII would have helped to prevent this event.

Title: CE550 AND BE23 HAD A NMAC AS THE CE550 ENTERED THE LNDG PATTERN FOR RWY 26 AT 3CK.

Narrative: WE WERE IN VFR CONDITIONS APPROX 15 NM NW OF 3CK, AND HAD A VISUAL ON THE ARPT. RPTED TO ATC, THE FIELD WAS IN SIGHT AND WERE CLRED FOR A VISUAL APCH. WITH VFR CONDITIONS WE CANCELLED THE IFR FLT PLAN. WE WERE ADVISED BY ATC OF NO OTHER TARGETS IN THE VICINITY OF 3CK AND WERE ABLE TO GO TO ADVISORY FREQ. WE HAD ALREADY BEEN MONITORING ADVISORY FREQ FOR SEVERAL MINS TO ESTABLISH OTHER TFC AND THE ACTIVE RWY. BTWN 10 AND 15 NM NW OF 3CK, THE FO MADE THE FIRST CALL TO 3CK TFC AND RPTED OUR POS, ALT, AND INTENTIONS (2400 FT MSL AND PLANNED TO ENTER FROM XWIND TO DOWNWIND RWY 26). APPROX 5 NM NW, FO CALLED AGAIN. ON THE XWIND TO RWY 26, I NOTICED A CESSNA DEPARTING FROM RWY 26 AND ON THE UPWIND. (I HAD NOT HEARD THIS ACFT RPT DEPARTING.) THE UPWIND ACFT RPTED US IN SIGHT AND WOULD FOLLOW. AT THIS TIME, FO MADE ANOTHER RPT 'ON XWIND TURNING DOWNWIND.' AT THAT TIME, THE FO EXCLAIMED THAT A PLANE JUST WENT PAST OUR R WING. AS I CONTINUED ON DOWNWIND, I TURNED TO LOOK TO MY L, TO SEE A BEECH SUNDOWNER AT MY 8 O'CLOCK POS AND APPROX 100 FT ABOVE, ON A NE HDG. THERE WAS NO TIME TO MAKE ANY ACTION TO FURTHER OURSELVES FROM THE OTHER ACFT. WE NEVER HEARD THE BEECH MAKE A CALL PRIOR TO REACHING THE PATTERN. AS WE CONTINUED ON DOWNWIND, A CALL WAS MADE FROM, POSSIBLY, THE BEECH, STATING, 'CITATION ON DOWNWIND AT LAKE IN THE HILLS, YOU ALMOST HIT A MUSKETEER!' FO THEN CALLED, 'TURNING BASE LEG TO RWY 26.' AFTER COMPLETING THE CALL, I OBSERVED THE BEECH, STILL AT APPROX 2500 FT MSL FLYING E. I COULD NOW SEE THE LNDG LIGHT WAS ON. AFTER MAKING THE RADIO CALL FOR BASE, THE ASSUMED, BEECH, MADE ANOTHER CALL, AGAIN STATING, 'CITATION, I DON'T KNOW IF YOU ARE LISTENING. YOU ALMOST HIT AN ACFT IN THE PATTERN ON DOWNWIND.' THIS CALL WAS HEARD, BUT WE DID NOT RESPOND IN ORDER TO AVOID A POTENTIAL DISPUTE ON THE RADIO, AND FOR THE FACT THAT WE WERE ESTABLISHED ON FINAL AND WERE FOCUSING ON THE LNDG. THE BEECH APPEARED TO TRANSIT THE AREA TO THE E AND DID NOT LAND AT 3CK, NOR DID IT MAKE ANY FURTHER RADIO CALLS. FACTORING INTO NOT SEEING THE BEECH WAS THE SUN IN OUR EYES, RIGHT AT THE RELATIVE POS OF THE ACFT (SE). ADDITIONALLY, WE HAD NOT HEARD ANY RPTS FROM THE BEECH PRIOR TO OUR ARR IN THE PATTERN. WE WERE ALSO UNDER THE ASSUMPTION OF NO OTHER TARGETS IN THE VICINITY OF 3CK. TCASII WOULD HAVE HELPED TO PREVENT THIS EVENT.
