3.8 Lubrication
3.8.1 Lubrication fundamentals
There are some inaccessible joints and control system parts inside a wing and fuselage,
which have been cleaned and lubricated during aeroplane assembly and next lubrication
will be performed during a periodic inspection.
On the other side there are some parts, e.g. landing gear, which are exposed to external
conditions and to varying loads. Those parts would be inspected during pre-flight and
periodical inspections and should be lubricated always when it necessary, but at least at
intervals specified below.
3.8.2 Recommended lubricants
The manufacturer recommends to use the greases and oil without acid for the
lubrication only.
