C. Short term storage (less than 6 months)
WARNING : PRIOR TO ANY OPERATION, ENSURE THAT THE KEY IS REMOVED FROM MAGNETO SELECTOR AND THAT "MAIN SWITCH" IS OFF.
IF AIRCRAFT IS EQUIPPED WITH DISCONNECT PLUG ON FIREWALL, DISCONNECT "MAGNETO DISCONNECT" PLUG AND CONNECT IT TO "GROUND MAGNETO FOR SERVICING" PLUG.
CAUTION : IF THE AIRCRAFT IS PARKED MORE THAN 10 DAYS, DISCONNECT THE EMERGENCY LIGHTING BATTERY (IF INSTALLED).
THE AIRCRAFT SHALL BE STORED WITH FULL TANKS TO AVOID EXCESSIVE CONDENSATION.
1) If the aircraft cannot be stored in a hangar, park it correctly and moor it - refer to 10-20-00.
2) Aircraft stored for a maximum period of 30 days or those which are intermittently flown during the first 25 hours are considered in short term storage with flight possibility.
WARNING : CHECK THAT THE MAGNETO SWITCH IS SET TO "OFF", THE THROTTLE IS CLOSED, THE MIXTURE CONTROL IS IN THE IDLE CUT-OFF POSITION, AND THE AIRCRAFT IS CORRECTLY MOORED BEFORE ROTATING THE PROPELLER BY HAND. DO NOT STAND WITHIN THE ROTATION AXIS OF THE PROPELLER BLADES WHILE ROTATING THE PROPELLER.
CAUTION : DO NOT ROTATE THE PROPELLER IN THE REVERSE DIRECTION TO AVOID DAMAGING THE VACUUM PUMP FINS.
3) Every seven days during these periods, the propeller shall be hand-rotated several revolutions. This makes oil circulate and thus prevents accumulation of corrosion on engine cylinders walls.
4) After 30 days storage, the aircraft shall be flown for at least 30 minutes, or a ground runup shall be performed until the oil temperature reaches the lower green arc range. Avoid prolonged runups.
5) Engine runup helps eliminate excessive accumulations of water in the fuel system and other air spaces in the engine. Keep fuel tanks full to minimize condensation in the tanks. Keep the battery fully charged to prevent the electrolyte from freezing in cold weather.
6) Every two weeks, rotate the wheels in order to prevent permanent deformation of the tires.
a) On the side of the tire, mark with a chalk the part of the tire in contact with the ground.
b) Pull the aircraft over a few meters, then put it back in its previous place so that another part of the tire comes into contact with the ground (the opposite part, if possible).
D. Long term storage (more than 6 months)
WARNING : PRIOR TO ANY OPERATION, ENSURE THAT THE KEY IS REMOVED FROM MAGNETO SELECTOR AND THAT "MAIN SWITCH" IS OFF.
IF AIRCRAFT IS EQUIPPED WITH DISCONNECT PLUG ON FIREWALL, DISCONNECT "MAGNETO DISCONNECT" PLUG AND CONNECT IT TO "GROUND MAGNETO FOR SERVICING" PLUG.
1) Preserve the engine : refer to engine maintenance handbook - refer to Service Letter L180 published by LYCOMING (latest current revision).
2) Blank off the carburettor air inlets and the exhaust pipes.
CAUTION : THE AIRCRAFT SHALL BE STORED WITH FULL TANKS TO AVOID EXCESSIVE CONDENSATION.
