C182 PLT LNDG RWY 3 AT MKC EXITS ONTO RWY 1 WHICH IS NOTAMED CLOSED FOR TKOF AND LNDGS. TOWER ADVISES NOT TO EXIT ON RWY 1 UNLESS CLEARED TO DO SO.

Narrative

I WAS FLYING THE PATTERN AT MKC. RWY 1/19 WAS CLOSED FOR LNDG AND TKOF OPS FOR THE DAY; BY NOTAM AND NOTICE ON THE ATIS. IT WAS OPEN FOR TAXIING FOR A PORTION OF ITS LENGTH; PRIMARILY BTWN THE INTXN WITH RWY 3/21; NORTHWARD TO TXWY D. I DID A FEW TOUCH-AND-GOES TO RWY 3; AND THEN REQUESTED CLRNC FOR A FULL STOP LNDG; AND WAS GIVEN CLRNC FOR RWY 3. AFTER LNDG ON RWY 3; I EXITED THE ACTIVE RWY L; ONTO RWY 1; AT THE INTXN WITH RWY 1/19 AND RWY 3/21. ABOUT 300 FT IN FRONT OF ME; ANOTHER GA ACFT WAS XING RWY 1 AT TXWY D; GOING W; MOVING FROM R TO L AS VIEWED FROM MY POS. MY SPD AT THAT TIME WAS ABOUT 25 MPH; AND THERE WAS NO RISK OF COLLISION; DUE TO THE SIGNIFICANT DISTANCE BTWN THE ACFT; AND OUR RELATIVE TAXI SPDS. THE TWR CTLR THEN DIRECTED THAT I 'NOT TURN ONTO RWY 1 WITHOUT PRIOR CLRNC TO DO SO.' THE PREVIOUS DAY; I HAD FLOWN INTO THE ARPT UNDER THE SAME SITUATION; LANDED ON RWY 3; AND WAS DIRECTED BY THE TWR CTLR TO 'TURN L ON RWY 1; SPD ALLOWING.' I HAD BEEN ABLE TO DO THIS; AND WAS DIRECTED TO THEN TAXI VIA TXWY D TO THE W RAMP. ON THE FOLLOWING DAY; THE DAY OF THIS INCIDENT; ACFT WERE AGAIN USING CLOSED RWY 1 AS A TXWY BTWN THE RWY INTXNS AND TXWY D. DUE TO THE FACT THAT RWY 1 WAS CLOSED FOR TKOFS AND LNDGS; I TREATED IT AS ANOTHER TXWY; AND EXITED THE ACTIVE RWY ONTO IT WITHOUT CLRNC. IN THIS CASE; I HAD A CLR VIEW OF THE AREA IN FRONT OF ME; AND NO HAZARD EXISTED. IF I HAD NOT EXITED ONTO THE CLOSED RWY 1; THEN TXWY D WOULD HAVE BEEN THE NEXT AVAILABLE RWY EXIT POINT; WHICH WOULD HAVE BEEN A 130 DEG TURN TO THE L; A MUCH GREATER TURN ANGLE; AND ONE IN WHICH VISIBILITY WOULD NOT HAVE BEEN AS CLR. WHAT COULD HAVE BEEN DONE TO PREVENT THIS OCCURRENCE? IF RWY 1; WHILE A PORTION OF IT IS CLOSED AND THE REST OF IT IS BEING ESSENTIALLY USED AS A TXWY; CANNOT BE TREATED AS A TXWY; IE; CLRNC MUST BE GIVEN TO EXIT ONTO IT; THEN IT WOULD BE HELPFUL; IN THIS UNUSUAL CASE; FOR ADVANCE NOTICE TO BE GIVEN TO THE PLT BEFORE LNDG NOT TO EXIT THE ACTIVE RWY ONTO THE CLOSED RWY WITHOUT PRIOR CLRNC.
