Narrative:

The student and I had just been handed off to rfd control tower, approximately 4 mi west of the airport entering a left base for runway 6. We contacted the tower and advised them we were on tower frequency. The tower controller said xyz cleared to land runway 6. I answered and told him we were planning a touch and go runway 6, like I had advised the approach controller. He then said, 'xyz cleared for full stop.' me: 'xyz roger full stop.' I understood his comment. There was a lot of jet traffic approaching and departing runway 36. He also advised in addition to cleared to land, to hold short of runway 18-36: 'xyz cleared to land, hold short of intersection 18-36.' approximately 20 seconds later new instructions were issued: 'xyz expect touch and go clearance on short final.' me: 'xyz.' we were now turning a 2 mi final, runway 6, when the controller advised, 'xyz cleared touch and go runway 6, turn right 090 degrees, altitude 2500' after departure.' I answered, 'thank you, xyz cleared touch and go runway 6, 090 degrees and 2500' after departure.' everything was fine up to now. The student made a nice crosswind landing, and was putting the flaps to 0, full power, carburetor heat off and staring down the runway. Everything normal. Now: there was a jet on ground control holding short of the runway when we were touching down. At that point he moved past the hold short line and I knew that he either wasn't listening to ground control or that the tower controller had not updated the ground controller as to our new clearance from full stop to touch and go. So, the jet pulled out onto the runway. I already sensed the jet was not going to stop, so I aborted the takeoff. Tower then said, 'xyz, stop, stop.' at that point we were almost stopped. The jet then crossed the runway in front of me, and I was cleared for takeoff from my stopped position on the runway. From what I remember I was cleared for the runway twice--once on base 'cleared to land' and once on final, cleared for touch and go.' I believe what contributed to the situation was a lot of traffic using runway 36, especially small business jets and such. Nothing I did, to my knowledge, contributed to the occurrence. Possibly too many aircraft being handled by too few controllers.

Title: GND CONFLICT WHEN BUSINESS JET BEGINS TO CROSS RWY WHERE SMA HAS BEEN CLEARED FOR TOUCH AND GO.

Narrative: THE STUDENT AND I HAD JUST BEEN HANDED OFF TO RFD CTL TWR, APPROX 4 MI W OF THE ARPT ENTERING A LEFT BASE FOR RWY 6. WE CONTACTED THE TWR AND ADVISED THEM WE WERE ON TWR FREQ. THE TWR CTLR SAID XYZ CLRED TO LAND RWY 6. I ANSWERED AND TOLD HIM WE WERE PLANNING A TOUCH AND GO RWY 6, LIKE I HAD ADVISED THE APCH CTLR. HE THEN SAID, 'XYZ CLRED FOR FULL STOP.' ME: 'XYZ ROGER FULL STOP.' I UNDERSTOOD HIS COMMENT. THERE WAS A LOT OF JET TFC APCHING AND DEPARTING RWY 36. HE ALSO ADVISED IN ADDITION TO CLRED TO LAND, TO HOLD SHORT OF RWY 18-36: 'XYZ CLRED TO LAND, HOLD SHORT OF INTXN 18-36.' APPROX 20 SECS LATER NEW INSTRUCTIONS WERE ISSUED: 'XYZ EXPECT TOUCH AND GO CLRNC ON SHORT FINAL.' ME: 'XYZ.' WE WERE NOW TURNING A 2 MI FINAL, RWY 6, WHEN THE CTLR ADVISED, 'XYZ CLRED TOUCH AND GO RWY 6, TURN RIGHT 090 DEGS, ALT 2500' AFTER DEP.' I ANSWERED, 'THANK YOU, XYZ CLRED TOUCH AND GO RWY 6, 090 DEGS AND 2500' AFTER DEP.' EVERYTHING WAS FINE UP TO NOW. THE STUDENT MADE A NICE XWIND LNDG, AND WAS PUTTING THE FLAPS TO 0, FULL PWR, CARB HEAT OFF AND STARING DOWN THE RWY. EVERYTHING NORMAL. NOW: THERE WAS A JET ON GND CTL HOLDING SHORT OF THE RWY WHEN WE WERE TOUCHING DOWN. AT THAT POINT HE MOVED PAST THE HOLD SHORT LINE AND I KNEW THAT HE EITHER WASN'T LISTENING TO GND CTL OR THAT THE TWR CTLR HAD NOT UPDATED THE GND CTLR AS TO OUR NEW CLRNC FROM FULL STOP TO TOUCH AND GO. SO, THE JET PULLED OUT ONTO THE RWY. I ALREADY SENSED THE JET WAS NOT GOING TO STOP, SO I ABORTED THE TKOF. TWR THEN SAID, 'XYZ, STOP, STOP.' AT THAT POINT WE WERE ALMOST STOPPED. THE JET THEN CROSSED THE RWY IN FRONT OF ME, AND I WAS CLRED FOR TKOF FROM MY STOPPED POS ON THE RWY. FROM WHAT I REMEMBER I WAS CLRED FOR THE RWY TWICE--ONCE ON BASE 'CLRED TO LAND' AND ONCE ON FINAL, CLRED FOR TOUCH AND GO.' I BELIEVE WHAT CONTRIBUTED TO THE SITUATION WAS A LOT OF TFC USING RWY 36, ESPECIALLY SMALL BUSINESS JETS AND SUCH. NOTHING I DID, TO MY KNOWLEDGE, CONTRIBUTED TO THE OCCURRENCE. POSSIBLY TOO MANY ACFT BEING HANDLED BY TOO FEW CTLRS.
