Analysis

DURING TAKEOFF ON A MAINTENANCE FERRY FLIGHT, WITH A MECHANIC FLYING FROM THE RIGHT SEAT, THE AIRCRAFT WOULD NOT ACCELERATE ABOVE V1 AND WOULD NOT ROTATE EVEN WITH FULL AFT YOKE. THE CAPTAIN ABORTED THE TAKEOFF AND THE AIRCRAFT WAS STOPPED AT THE END OF THE RUNWAY WITH THE RIGHT GEAR ON THE OVERRUN AREA. AFTER THE AIRCRAFT STOPPED, CREWMEMBERS EXTINGUISHED TWO SMALL FIRES IN THE MAIN GEAR BRAKES. INVESTIGATION DID NOT REVEAL THE REASON THE AIRCRAFT WOULD NOT ACCELERATE, HOWEVER IT WAS NOTED THAT BOTH MAIN BRAKE ASSEMBLIES HAD BEEN SUBJECTED TO EXTREME HEAT AND RAPID COOLING. IN ADDITION, ALL OF THE BRAKE PUCKS WERE WORN THIN. THIS DAMAGE WAS CONSISTENT WITH TAKING OFF WITH THE PARKING BRAKE ENGAGED OR INADVERTENT APPLICATION OF THE TOE BRAKES DURING TAKEOFF ROLL.
