DR 611851627 PIPER PA25 235–ATA 2720 RUDDER CONTROL SYSTEM–CABLE–DAMAGED. Damaged rudder cables were noticed after removing turtle deck. Preliminary examination indicated that cables may have been lubricated where they ran through the plastic guide bushes down to the rear sides of the fuselage. Cables were covered in dust which had adhered to the lubricated cables, forming a grinding paste. Maintenance organisation has been notified. RH rudder cable had approx. 60% of the wire strands broken. Whereas LH cable was similarly damaged with approx. 40% of wire strands broken.
