3.1 Overall maintenance survey
The aeroplane maintenance is a care and repairs of an aeroplane to save its airworthiness.
There are performed periodical events ( periodical and pre-flight inspections ) and irregular
events e.g. a repair of a damage.
3.2 Daily inspection
The daily inspection must be performed before every flight day of the ultralight aeroplane.
A method of the daily inspection execution is the object of a pilot training. The scope of
this inspection is specified in the Flight Manual and in the additional documents supplied
with an aeroplane instruments or equipment. Special attention must be devoted to the parts,
which are affected by the high vibrations and high temperatures from a powerplant.
These parts are especially:
- a propeller attachment
- an exhaust system ( a muffler )
- an engine attachment
- a wiring, especially an ignition system
- a lubrication system, a cooling system and a fuel system
3.3 Pre-flight inspection
This inspection is shorter than a daily inspection whereupon the pre-flight inspection
should be performed before each flight. The Flight Manual presents more information
about a pre-flight inspection. If any problems are found they must be corrected before
flying.
