5. Engine Cleaning
Use a cold cleaning agent (e.g. Berner Cold Cleaner No.13618.0).
CAUTION: DO NOT CLEAN THE ENGINE WHILE THE ENGINE IS HOT.
CAUTION: DO NOT USE HIGHLY FLAMMABLE OR CORROSIVE CLEANING
AGENTS TO CLEAN THE ENGINE.
CAUTION: DO NOT LET THE CLEANING AGENT GET INTO ELECTRICAL
COMPONENTS AND ENGINE INTAKES.
CAUTION: DO NOT START THE ENGINE UNTIL ALL OF THE CLEANING AGENT
HAS EVAPORATED.
Protect all electrical components and cables. Use polythene bags to seal intakes and other areas that
you want to keep dry. After washing you can dry the engine using compressed air (< 8 bar (116 PSI).)
6. Snow and Ice Removal
Remove snow and ice as soon as possible to prevent water from the melting snow or ice re-freezing
and causing damage.
CAUTION: DO NOT USE SHARP OBJECTS TO REMOVE SNOW OR ICE. YOU
CAN DAMAGE THE AIRPLANE STRUCTURE.
Use soft brushes to remove snow from the surfaces.
Put the airplane in a heated hangar to remove ice or spray de-icing fluid onto ice-covered surfaces
using a suitable spray bottle. For approved de-icing fluids refer to AFM, Section 8.7.
Use a soft piece of cloth to wipe the airplane dry.
