Inspection and testing of springs• any exposed springs are carefully inspected for signs of either of
the problems of corrosion and overheating.
• The manufacturer will publish the exact dimension of
the unloaded spring with some small tolerance, whilst
the servicing technician will accurately measure thespring’s length and compare the two dimensions.
• Providing that the spring is within the published figures, then the
spring is considered to be serviceable.
• The other check, is the load/deflection check.
• A special test rig is used, to load the spring with either a
compressive, tensile or a torsional loading and a meter on the rig
will display the load versus deflection figures. A series of loads are,
subseuently, applied to the spring and the relevant deflections
noted.

Testing, cleaning ! inspection of bearings
"efore a bearing can be checked it must be cleaned thoroughly toremove any dirt and the old lubricating fluid.
• #emove any excess grease with clothes and dry compressed air,
whilst ensuring that the rolling elements remain stationary or only
rotate slowly.
• $oak the bearing in an approved solvent, such white spirit, to
remove the remaining grease. The solvent may be applied as a
forced %et if necessary.
• &ry the bearing by using clean warm and dry compressed air,
again avoiding fast rotation of any rolling elements.
• 'ightly lubricate all bearing surfaces with oil to prevent the onset
of corrosion.

'ubrication reuirements of bearings
(xcessive heating of a bearing manifests itself as discoloration of the
rings, rolling elements and cages from gold to blue.
)ailure or lack of lubrication often has similar signs as overheating.
The outcome of either overheating or lubrication failure will alwaysresult in the eventual failure of the bearing, so it should be re%ected
as unserviceable.
*f a bearing is to be used immediately after inspection, it should be
lubricated with correct lubricant and installed.
*f there is liable to be a delay before installation, then the bearing
should be coated in rust+preventing inhibiting oil, wrapped in
greaseproof paper, boxed and labeled. The bearing should always be
stored horiontally, in a clean dry atmosphere.

Inspection of gears, bac0lash
-ear in gears, assuming that the bearings are
not worn, will be found on the faces of the gear
teeth. This wear shows up as excessive
backlash, which can be easily found by simply
rotating the input mechanism, such as the main
drive shaft, whilst holding the output rigidly. *t
should be borne in mind that a small amount ofbacklash is essential for the correct operation of
bearings.

*nspection of belts and pulleys, chains and
sprockets"elts checked before each flight. The belts must also be checked, at
regular intervals, for signs of wear, a tension check on the either the
belt itself or the tensioning mechanism.
The ma%ority of belts whatever their usage, have a finite life and are
also sub%ect to 0on+condition’ monitoring.1ne of the ma%or checks should be that the chain passes smoothly
over the sprockets. *f there is any roughness or binding, then further
checks will be reuired.
Another ma%or check of the chain assembly is that for wear, which
involves applying a load to detect whether the chain is worn.2hains should also be checked for normal faults that can befall most
mechanisms3 these include damage, corrosion, cleanliness and
insufficient lubrication.
2heck for chain elongation as per the manual,

*nspection of screw %acks, lever devices, push+pull
rod systems$ome screw %acks are in the form of actuators and some are used to drive
flaps and other aerodynamic devices.
*n+service checks, other than lubrication will probably only include backlash
checks on the actuating shaft. These will probably mean no more than a
side+to+side hand movement of the rudder trim tab, which ensures that the
movement is not excessive.

levers will be used to transmit thrust from one medium to another.
Apart from the bearings of the lever reuiring lubrication, unless they are
sealed+for+life bearings, there is little maintenance reuired, other than
physical checks for damage, distortion and cracks.
The ma%ority of aircraft push+pull systems can be found in both the flying
and engine controls.

$waging of end fittings
All cables, used in aircraft controls runs, have some form of end
fittings attached to each end of the cables.
&uring production of these cables, the completed end fitting will be
carefully checked, using a 4o/5o+4o gauge, to ensure that the cable
has been gripped satisfactorily. The finished cable assembly will also
be proof tested to confirm the end fitting attachments and to proveits suitability for use as an aircraft control cable.

*nspection and testing of control cables
• swaged end fittings will reuire minimal inspection. *n someinstallations, red paint is applied at the %unction of the end
fitting where the cable emerges, leading to a gap showing if
the cable has slipped within the swaged end fitting during
normal service.
• $ome individual ferrules, fitted to non+critical cables, may be
inspected for signs of cracking whilst in service.
• checked for stretch by measuring their length under load, or
they will be given a finite life and replaced when that life is
reached.
•2able systems have to receive regular inspections due totheir being sub%ect to a wide variety of environmental
conditions and wear.
• Their degradation, due to wear, can take the form of
wire/strand breakage which is fairly easy to detect, or may
exist as less visible internal wear, or as corrosion and
distortion. 13

"owden cables, aircraft flexible control systems
+O4$" C+'$*
is a type of flexible cable used to transmit mechanical
force or energy by the movement of an inner cable most
commonly of steel or stainless steel relative to a hollow
outer cable housing.
6sed as push pull cable. The push+pull cable is thus
ideal for usage in extreme temperature conditions where
significant heat is generated.
cables are thus safe to use in applications such as turbo+engine bays and exhaust manifolds, Accelerator cables,
2lutch cables, 7andbrake cables
