Narrative:

My flight was cleared for takeoff and the clearance was acknowledged. We began the takeoff roll and at approximately 40-60 KTS, the tower cancelled our takeoff clearance. At approximately 1/3 the way down the runway, medium large transport Y had moved onto the active runway, crossing while taxiing to a parallel runway. I never heard the clearance for medium large transport Y to cross the runway. I think the aircraft was cleared by ground control. I think all aircraft using/crossing runway's in use should be on the same frequency. Callback conversation with reporter revealed the following: reporter reported this incident to his company and requested that they conduct an investigation. This was done, and it was learned that the ground controller had cleared the medium large transport to cross the runway west/O proper coordination with the local controller. Tower personnel said they would not process an operational error, because the taxiing aircraft never did reach the runway before reporter's aircraft was stopped. Reporter disagrees with this finding because he was up to 60 KTS and had just sighted the medium large transport on the runway when the tower ordered him to cancel takeoff clearance.

Title: TKOF CLRNC GIVEN AND THEN CANCELLED BECAUSE OF ACR MLG CROSSING RWY.

Narrative: MY FLT WAS CLRED FOR TKOF AND THE CLRNC WAS ACKNOWLEDGED. WE BEGAN THE TKOF ROLL AND AT APPROX 40-60 KTS, THE TWR CANCELLED OUR TKOF CLRNC. AT APPROX 1/3 THE WAY DOWN THE RWY, MLG Y HAD MOVED ONTO THE ACTIVE RWY, XING WHILE TAXIING TO A PARALLEL RWY. I NEVER HEARD THE CLRNC FOR MLG Y TO CROSS THE RWY. I THINK THE ACFT WAS CLRED BY GND CTL. I THINK ALL ACFT USING/XING RWY'S IN USE SHOULD BE ON THE SAME FREQ. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR RPTED THIS INCIDENT TO HIS COMPANY AND REQUESTED THAT THEY CONDUCT AN INVESTIGATION. THIS WAS DONE, AND IT WAS LEARNED THAT THE GND CTLR HAD CLRED THE MLG TO CROSS THE RWY W/O PROPER COORD WITH THE LCL CTLR. TWR PERSONNEL SAID THEY WOULD NOT PROCESS AN OPERROR, BECAUSE THE TAXIING ACFT NEVER DID REACH THE RWY BEFORE RPTR'S ACFT WAS STOPPED. RPTR DISAGREES WITH THIS FINDING BECAUSE HE WAS UP TO 60 KTS AND HAD JUST SIGHTED THE MLG ON THE RWY WHEN THE TWR ORDERED HIM TO CANCEL TKOF CLRNC.
