IMMEDIATELY UPON STARTING ROTATION AND LARGE UN-COMMANDED DOWNWARD PULLING FORCE WAS EXERTED ON THE AIRCRAFT FORCING THE NOOSE BACK ONTO THE RUNWAY. WITH KNOWLEDGE OF THE REMAINING RUNWAY MARK AND IMMEDIATELY INITIATED ABORTED TAKEOFF PROCEDURES. WHILE ABORTING IT BECAME AWARE THAT OUR DIRECTIONAL CONTROL ABILITY WAS IN QUESTION. WE SAFELY EXITED THE RUNWAY AND TAXIED BACK TO JET CENTER. AFTER EXITING THE AIRCRAFT WE HAD BECOME AWARE THAT DAMAGE TO THE RIGHT MAINS HAD OCCURRED.
