Aircraft; Human Factors
Preflight and taxi were normal operations. We were cleared for takeoff; and as I brought the power to takeoff I felt that the airplane was rolling. I thought that I may not have enough pressure on the brake pedals and pushed harder; making sure that my feet were fully up on the brake pedals. The airplane continued to move and I released the brakes. I heard a noise as I released the brakes which I attributed to a normal shift of interior contents. The PM asked if I heard that and I replied that I thought it was normal. I then felt a slight rumble as the airplane accelerated. I heard the PM call for the abort about the same time I was coming to that decision myself. I reduced the power to idle and deployed the TRs. We were at a relatively slow speed so I gingerly applied brake pressure. There did not seem to be any effect even as I increased brake pressure; released and reapplied brakes. I then turned the anti-skid off and the brakes responded. The PM was in contact with the Tower and we turned off the runway. The Tower asked if we wanted to continue to the ramp and the PM and I elected to remain stopped and assess the airplane before further movement. He indicated that the right main tires were blown and we shut down on the taxiway. The inboard left main tire was also blown. I called the [Duty Manager] and coordinated with ground personnel to have the airplane brought to the hangar.
G200 Captain notes that the brakes cannot hold the aircraft stationary as the thrust is pushed for takeoff. The brakes are released and a rumbling noise is heard resulting in a rejected takeoff. Initial braking has no effect until the antiskid is turned off and the aircraft is brought to a stop. Three of the four main gear tires are found to be deflated.
