What was found
PILOT FELT LOSS OF ELEVATOR AUTHORITY DURING TAKEOFF ROLL. TAKEOFF WAS ABORTED WITHOUT INCIDENT AND AIRCRAFT WAS TURNED OVER TO MAINTENANCE. THE RIGHT AFT ELEVATOR CONTROL CABLE WAS FOUND FRAYED AND BROKEN BETWEEN THE TWO UPPER PULLEY SETS. INSTALLATION OF A NEW CABLE USING SAME ROUTING REVEALED THAT CABLE COULD CHAFE ON A BOLT THAT RETAINS THE YAW DAMPENER SERVO. FURTHER INSPECTION SHOWED THE RUDDER CABLE (RIGHT) AND ELEVATOR CABLE CROSSED BETWEEN THE UPPER PULLEY SETS. CORRECTION OF CABLE ROUTING ELIMINATED CHAFE SITUATION. RUDDER CABLE WAS NOT CHANGED WITH ELEVATOR CABLE. THIS AREA IS DIFFICIULT TO INSPECT DUE TO BLEED AIR PLUMBING.
