UTD interferes with wire strike capabilities. CAUTION Never  install  cables  where  they  can  be  damaged. Use  wire  bundle  ties  or  clamps  to  route  cabling along or through airframe instead of securing cables with  fairing  doors,  panels,  or  seat  frames.    Never bundle tie cables to flight controls.
