7.Service life of airplane and maintenance periodicity
Regular and careful proceeding of the maintenance is the principle of reliable and safe operating
of the airplane. The garantee inspection and the inspections after 100 and 300 hours should be
written down to flight book.
7.1.Service life of the plane and its parts
The service life as one part consist of the service life of decisive parts which are the airframe,
engine and the airscrew. Wear of the airplane depends on its stress and that’s why you should
keep away from high stress on the construction, especially by high flight multiples. Do not
disassembly the airplane needlessly and anchore the airplane only introduced way. Also keep
away from landing in high lawn, which can expressively take the trouble on the airscrew.
Regular conservation with high quality car vosk expressively terminates aging of the varnish.
Park the airplane in covered hangar if possible, at least, protect the airplane against unfavorable
influence by covering.
Initial life service of the airframe is 1000hours or 5 years from the date of production. Hereafter,
it will be trimmed by the operating experience.
There is no service life of the engine. The engine is subject to revision after every 1200 hours in
a service center, where is the service life specified.
The service life of the airscrew is not set, it undergoes regular revisions at the producer. The
service life will be specified due to its factual state.
7.2.Workaday maintenance
When buying a new airplane, check especially tightening the pipes on the engine and the state of
the fuel filter. Check also carefully all places where the pipes are taped to metal parts of the
engine-for example suction piping.
ATTENTION!
Change the fuel filter preventively after first ten flight hours.
We can not exclude the possibility of getting dust or other dirt into the tank of the fuel system
while producing the airplane. First rinsing of the tank and the fuel system before the filter can
bring its exceptional contamination. If your airplane is equipped with tanks in the wings, each of
them is equipped by independent fuel filter. These filters are approachable after taking off the
seats. Check these filters and change them preventively after 150litres of fuel overdraft. / from
each tank /
Use preferentially filters with clear housing. Workaday maintenance consists of before flight
inspection and the engine test, they are introduced in point 6.6.
