MISCOM BTWN GA PLT AND DEP CTLR LEADS TO INCIDENT RPT.

Narrative

I RECEIVED CLRNC FROM ZKC ON THE GND AT SLN. I WAS GIVEN A 10 MIN WHEELS-OFF TIME. DURING THE TAXI; I MONITORED BOTH ZKC AND THE TWR FREQ (119.3). ATC AMENDED MY ALT FROM 6000 FT TO 4000 FT DURING THE TAXI. I ACKNOWLEDGED THE CLRNC. I TAXIED TO RWY 35 AND DEPARTED WITHIN THE 10 MIN PERIOD ACCORDING TO MY CLOCK. AFTER TKOF AND WITH THE AIRPLANE TKOF CHKLIST COMPLETED (HEADS UP AURAL CHKLIST); I CONTACTED ZKC. THE CTLR INDICATED THAT I WAS ALMOST 2 MINS LATE. I INDICATED THAT MY WHEELS OFF WAS WITHIN 10 MINS. SHE STATED THAT SHE WAS HOLDING A PLANE AT THE VOR. THE TCASII INDICATED A PLANE 6 MI FROM MY PLANE AT THE POINT WHERE I WAS 1+ MI FROM THE END OF THE RWY; WHICH MEANS THAT THE OTHER PLANE WAS AT LEAST 7 MI FROM THE END OF RWY 35. IF THE CTLR PERCEIVED A POTENTIAL PROB; SHE COULD HAVE INFORMED ME PRIOR TO THE 10 MIN WHEELS-OFF RESTR. AT NO TIME WAS THERE ANY THREAT OF INCIDENT WITH ANOTHER ACFT. THE CTLR SHOULD HAVE AMENDED MY CLRNC IF SHE FELT THERE WAS A POTENTIAL PROB AS SHE HAD ALREADY DONE REGARDING THE ALT AMENDMENT. WITH MY TCASII SYS; I WAS ABLE TO MAINTAIN SAFE SEPARATION AT ALL TIMES.
