Narrative:

I was approaching ojc from the southwest on a heading of 064 degrees, and had been cleared by kansas city approach to 3000 ft. Beginning at approximately 15 mi from the airport I had begun to monitor the tower frequency 126.0 on my second radio, while maintaining contact with approach. Nearing the airport I heard on the tower frequency an small transport twin cleared for VFR departure to the southwest, and he was advised of my incoming flight. Hearing this, I turned on all lights, including navigation, beacon, strobe, landing and taxi lamps. Shortly thereafter, I notified approach that I had the airport in sight, and at this time, my DME was reading 6.9. I was cleared for a visual approach to runway 17 and told to contact tower on 126.0. Simultaneously with radar service being terminated I was advised that traffic was departing ojc to the southwest. I contacted the tower and reported my position at 6.5 mi southwest, with ATIS information for a landing runway 17. Tower immediately advised that an small transport had departed runway 17 and was climbing west. I was advised to enter a right downwind for runway 17, but during the transmission I spotted the small transport through the haze climbing straight for me. I immediately reduced power to idle, and executed a right turn while the small transport passed overhead in close proximity. At no time did the small transport appear to execute evasive action, nor were any lights visible on the aircraft. I reported to tower that I had lost the last part of their communications because of the incident, and shortly thereafter the tower stated that I was in sight and cleared to land. At no time did I hear any communications with the small transport. In reviewing the situation, I do not see that any errors were committed by anyone, but felt that in keeping with the purpose of the NASA system as I understand it, felt that this incident should be reported. There is considerable traffic around ojc, and I have seen a number of incidents like this one. Hopefully, tower radar to be installed this fall will reduce the number of such incidents.

Title: NMAC BTWN AN SMA SEL AND AN SMT TWIN.

Narrative: I WAS APCHING OJC FROM THE SW ON A HDG OF 064 DEGS, AND HAD BEEN CLRED BY KANSAS CITY APCH TO 3000 FT. BEGINNING AT APPROX 15 MI FROM THE ARPT I HAD BEGUN TO MONITOR THE TWR FREQ 126.0 ON MY SECOND RADIO, WHILE MAINTAINING CONTACT WITH APCH. NEARING THE ARPT I HEARD ON THE TWR FREQ AN SMT TWIN CLRED FOR VFR DEP TO THE SW, AND HE WAS ADVISED OF MY INCOMING FLT. HEARING THIS, I TURNED ON ALL LIGHTS, INCLUDING NAV, BEACON, STROBE, LNDG AND TAXI LAMPS. SHORTLY THEREAFTER, I NOTIFIED APCH THAT I HAD THE ARPT IN SIGHT, AND AT THIS TIME, MY DME WAS READING 6.9. I WAS CLRED FOR A VISUAL APCH TO RWY 17 AND TOLD TO CONTACT TWR ON 126.0. SIMULTANEOUSLY WITH RADAR SVC BEING TERMINATED I WAS ADVISED THAT TFC WAS DEPARTING OJC TO THE SW. I CONTACTED THE TWR AND RPTED MY POS AT 6.5 MI SW, WITH ATIS INFO FOR A LNDG RWY 17. TWR IMMEDIATELY ADVISED THAT AN SMT HAD DEPARTED RWY 17 AND WAS CLBING W. I WAS ADVISED TO ENTER A R DOWNWIND FOR RWY 17, BUT DURING THE XMISSION I SPOTTED THE SMT THROUGH THE HAZE CLBING STRAIGHT FOR ME. I IMMEDIATELY REDUCED PWR TO IDLE, AND EXECUTED A R TURN WHILE THE SMT PASSED OVERHEAD IN CLOSE PROX. AT NO TIME DID THE SMT APPEAR TO EXECUTE EVASIVE ACTION, NOR WERE ANY LIGHTS VISIBLE ON THE ACFT. I RPTED TO TWR THAT I HAD LOST THE LAST PART OF THEIR COMS BECAUSE OF THE INCIDENT, AND SHORTLY THEREAFTER THE TWR STATED THAT I WAS IN SIGHT AND CLRED TO LAND. AT NO TIME DID I HEAR ANY COMS WITH THE SMT. IN REVIEWING THE SIT, I DO NOT SEE THAT ANY ERRORS WERE COMMITTED BY ANYONE, BUT FELT THAT IN KEEPING WITH THE PURPOSE OF THE NASA SYS AS I UNDERSTAND IT, FELT THAT THIS INCIDENT SHOULD BE RPTED. THERE IS CONSIDERABLE TFC AROUND OJC, AND I HAVE SEEN A NUMBER OF INCIDENTS LIKE THIS ONE. HOPEFULLY, TWR RADAR TO BE INSTALLED THIS FALL WILL REDUCE THE NUMBER OF SUCH INCIDENTS.
