CONTROL CABLES
9.3.1 DESCRIPTION
Control Cables are of the enclosed push-pull type, fitted with spherical bearings at both ends. To
operate, the outer cover of the cable must be clamped firmly at each end.
9.3.2 CONTROL CABLE REMOVAL
1.
Unbolt the connections (rod end bearings) at either ends of the cable.
2.
Unbolt the clamps at either end of the cable.
3.
Where required, remove any ties etc used to restrain the cables in the aircraft.
4.
Tie a string or light wire to one end of the cable.
5.
Draw the cable out of the aircraft, leaving the string/wire in place to allow installation of a
replacement part.
9.3.3 CONTROL CABLE INSPECTION & REPAIR
Control cables must be inspected in accordance with the details given in Section 4.16. Note that this
is not normally part of a 100-hourly inspection. The cable clamp inspections given below are a part
of a normal 100-hourly however.
Repair of control cables is limited to the installation of new parts.
The Figures below show various pictures of the cable clamps and cable assemblies. Points to note,
and which must be checked during routine maintenance, include:
-
Primary cables have a green outer sheath with machined end fittings.
-
Trim cables have a black outer sheath with a visible crimp on the end fitting.
-
Primary cable clamps are smaller than trim cable clamps and have square corners.
-
Primary cable backing plates are smaller, have a slotted hole and are made from aluminium.
-
The two cables are made by different manufacturers and the clamps are supplied by each
manufacturer to suit. The correct type of clamp must be used with each cable.
-
The rubber seal of primary control cables must be pulled back slightly to allow the clamps to be
installed properly.
-
Both cables use clamps which work by the same means: the clamp has a locking tang which
inserts into a groove machined in the cable end fitting.
