Stains Or Damage To Radiating Surface - Magni Gyro M16C Ordinary Maintenance Manual

M16 (C) TANDEM TRAINER
MAINTENANCE MANUAL
3.13.3 STAINS OR DAMAGE TO RADIATING SURFACE
Loss of coolant liquid can cause engine temperature rising and lead to damages to the engine; in some cases it can
also lead to emergency landing.
WARNING DANGER:
In case of slight dripping (indicated by small stains, no continuous dripping and no damaged radiant
surface) and only in case of extreme need, the gyroplane might fly again. But, in such a case, some
special "Radiator Stop Leak" solution must be used, mixed with the coolant liquid.
This is only a temporary solution allowing the gyroplane to fly to a service centre. During such a flight, it is
necessary to check the leak(s) and levels every 30 minutes of flight.
WARNING DANGER:
In case of large leaks and evident dripping, or if the liquid damages the radiant surface, the radiator
must be replaced as soon as possible.
3.13.4 REPLACEMENT OF RADIATOR
(See Fig. 3.13/1 ‐ 3.13/3)
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. Loosen the clamp pn 384 that attaches the hose pn 1240 to the lower connection of the radiator;
3. Have a tray (5) ready to collect the coolant;
4. Gently remove the hose pn 1240 from the radiator connection and direct the liquid into the tray;
5. To allow the complete discharge of the coolant from the cooling system, remove the cap (2) of the
engine's recovery reservoir (3);
6. Loosen the clamp pn 384/1 connecting the elbow pn 385 to the upper connection of the radiator;
7. Remove the elbow pn 385 from the radiator;
8. Unscrew the 4 locking bolts M6x12 of the radiator as well as the lock washers (6) and washers 6x12;
9. Remove the locking bolts M6x16 and then the radiator (4) from the frame of the radiator choking system
pn 390;
10. Fit the new radiator and fix it with the bolts M6x16 (replacement of the lock washers (6) is
recommended at each removal);
11. Insert the elbow pn 385 on the special radiator connection and tighten the clamp pn 384;
12. Put the hose pn 1240 on the special radiator connection and tighten the clamp pn 384;
13. Fill the system from the engine's expansion tank, following the level indications given in paragraph
3.13.7;
14. Close the cap (2) of the engine's expansion tank (3).
3.13.5 ENTIRENESS OF COOLING SYSTEM HOSES
WARNING:
The flexible hoses pn 1240 and pn 540 have an inner steel spiral to prevent flattening of the inner
diameter on bends. If some part of the hoses rubs against some metal or sharp edge, producing tearing
or abrasion of the outer surface of the hose, this hose must be replaced. Furthermore, the
rubbing and contact must be reduced.
