Narrative:

Passing through 15500 ft, climbing out of mci, ZKC called out traffic, VFR, last known altitude of 16.5 MSL. Our TCAS picked him up 700 ft above, about 10-15 mi ahead. TCAS called to reduce climb. We searched visually and did not see the traffic. The ivsi and TCAS then stated to descend to 1400 FPM. The captain assumed control of aircraft and descended immediately. The TCAS called out at 15000 ft the end of the conflict. We leveled out at 14700 ft and resumed climb. ZKC stated there was no other conflict. However, we entered kc approach airspace below 15000 ft. They filed a TCAS pilot deviation. At no time did we see the traffic. The traffic had cancelled IFR with the center was not talking to anyone at the time.

Title: TCASII CAUSES DSCNT. ACFT ENTERED MCI APCH CTL AIRSPACE WITHOUT COORD.

Narrative: PASSING THROUGH 15500 FT, CLBING OUT OF MCI, ZKC CALLED OUT TFC, VFR, LAST KNOWN ALT OF 16.5 MSL. OUR TCAS PICKED HIM UP 700 FT ABOVE, ABOUT 10-15 MI AHEAD. TCAS CALLED TO REDUCE CLB. WE SEARCHED VISUALLY AND DID NOT SEE THE TFC. THE IVSI AND TCAS THEN STATED TO DSND TO 1400 FPM. THE CAPT ASSUMED CTL OF ACFT AND DSNDED IMMEDIATELY. THE TCAS CALLED OUT AT 15000 FT THE END OF THE CONFLICT. WE LEVELED OUT AT 14700 FT AND RESUMED CLB. ZKC STATED THERE WAS NO OTHER CONFLICT. HOWEVER, WE ENTERED KC APCH AIRSPACE BELOW 15000 FT. THEY FILED A TCAS PLT DEV. AT NO TIME DID WE SEE THE TFC. THE TFC HAD CANCELLED IFR WITH THE CENTER WAS NOT TALKING TO ANYONE AT THE TIME.
