9.2. Aircraft Repairs
Each damage, which may have an influence on airframe strength or flight characteristics must be
reported to the Manufacturer. The Manufacturer determines a way of repair.
Minor repairs mean the repairs of those parts, which substantially do not take a part in the aircraft
function and stiffness. Among permitted repairs belongs:
• paint repairs
• worn-out parts exchange
• repairs of wheel tyres
Above mentioned minor repairs can be carried out by the owner himself. Repairs of torsion box, spars,
wings and tailplane, landing gear and fuselage load-bearing structure must be carried out by authorized
or specialized workshop. If any surface repairs or changes, a white tone colour must be kept on upper
surface exposed to the sunshine.
9.3. Engine Major Overhaul
The major overhaul is carried out after 2000 flight hours but not later than 10 years after putting the
aircraft into operation, unless decided otherwise based on regular technical inspection or by the
Manufacturer´s bulletin. The overhaul is performed by authorized or special workshop. The overhaul
and maintenance are carried out according to manual of the engine producer.
9.4. Anchorage of the Aircraft
Anchorage of the aircraft is necessary in order to avoid eventual damage caused by wind or wind blasts
during parking outside the hangar. For this purpose, the aircraft is equipped with screw mounting points
for eyelets on the underside of the wingtips.
9.5. Cleaning and Care
The aircraft surface should always be treated with suitable cleaning agents. Oil and grease remnants can
be removed from the aircraft surface by suitable smooth active substances or alcohol. The canopy
should be only cleaned with a sufficient tepid water flow with addition of suitable smooth active
substances. Never use petrol or chemical solvents. Do not use water jet stream for airframe cleaning
and avoid water inlet into Pitot-static system, engine compartment, ventilation holes and other open
areas on the airframe.
