For detailed explanations concerning control cables refer to
AC 43.13-1B, chapter 7, section 8. Inspection and Repair
of Control Cables and Turnbuckles.
Inspection Procedure
Refer to the Control Cable Replacement Criteria Paragraph.
1 Visually inspect the structure and other components located
next to fairleads for cracks and traces of lubrication splashes
caused by control cable wires sticking out. Those evidences
can indicate a damaged control cable.
2 Perform the following inspection item with the pedal
adjusted first to the foremost and later to the rearmost
position in order to get access to the control cable inside
the S-shaped cable guide.
3 Visually inspect the PTFE-hoses in the areas of the fuselage
skin penetration and of the S-shaped cable guide of the pedal
adjustment for wear and other damage.
N O T E Intact PTFE-hoses render a close inspection of the
control cable inside the hose unnecessary.
4 Inspect shrinking sleeves fixing the fuselage skin
penetration PTFE-hose for function and damage.
5 Inspect shrinking sleeves at the control cable end fittings
for wear and other damage.
N O T E Intact shrinking sleeves render a close inspection of the
control cable inside the sleeve unnecessary.
6 Disconnect the control cable from the rudder to relieve
cable tension. Refer to
Removal Paragraph.
7 Move the rudder control cables during inspection to ensure
that the entire cable run including areas of fairleads is visible
respectively accessible.
C A U T I O N Risk of injuries due to broken wires possible. Wear
protective gloves.
8 Closely inspect control cables by passing a cloth over them
to snag on broken wires.
