Air Filter Replacement - Magni Gyro M16C Ordinary Maintenance Manual

3.17.2 AIR FILTER REPLACEMENT
WARNING DANGER:
The air filter (RU 800 or RU 810) must be replaced exactly as prescribed in the maintenance schedule,
except if the gyroplane is used in a very dusty situation. In that case, the inspection and replacement
should occur twice as often.
1. Before starting verify that the engine's ignition key and push‐button are in OFF position and that all the
breakers are switched OFF;
2. Completely remove the safety wiring (3) of the filter;
3. Loosen the fixing clamp (2) and remove the filter RU800;
4. Install a new filter, as per specifications requested in the latest version of the spare parts catalogue;
5. Restore the safety wiring of the filter (3);
NOTE:
As the RU800 filter installed on the Rotax 914 engines are not preset for safety wiring, pierce the collar
of the filter (1) with the safety wire.
6. Place and tighten the filter fixing clamp (2);
7. Finish the safety wiring of the filter (3), anchoring the filter to the engine.
CAUTION:
It is strongly recommended to check the tightening of the filter fixation clamp after one hour of use of
the engine after having replaced the filter. This to compensate a possible play due to the alteration of
the collar of the filters.
3.18 PROPELLER MAINTENANCE
Before each flight the blades must be carefully inspected. The inspection should look for signs of impact,
particularly on the leading edges. Evidence of cracks or defects in the blade coating should also be looked for.
There should be no signs of play between the blade and hub. A clean finger should be run around the rod end and
provide no trace of grey or black dust.
3.18.1 CLEANING INSTRUCTIONS
The composite blades can be cleaned using household detergents and water. Polyurethane coated blades may be
cleaned using soap or car polish. Regular cleaning and inspection of the blades will keep them at their peak
performance. The leading edge tape should be replaced if showing signs of wear (the addition of the tape does not
detract from the aerodynamic performance of the blades).
Each blade is balanced before leaving the factory and any unauthorised re‐painting will degrade this balancing.
Examination of the blade rod‐ends will reveal a factory sticker containing the factory balancing repair number. The
sticker is used to cover a balancing hole which contains small lead balls providing the fine balance to the blades.
The lead balls may sometimes move within the hole, this is acceptable. However, if the sticker becomes loose, or
detached, the balls may be lost and the propeller balance destroyed. Do not remove the sticker that indicates
Factory's balancing number for repair.
