8.20 Operation in Tropical Conditions
The following measures are necessary to protect the engine against heat and dust:
Air filter
If the engine is operated in areas of high dust accumulation install larger air filter
(contact your aircraft manufacturer for details).
Oil-measuring stick
Seal oil-measuring stick by inserting a felt washer below the oil stick cap.
To achieve a tight fit of the oil stick in its guiding tube, bend stick as necessary.
Liquid cooling
If the engine is operated routinely at high ambient temperatures, a larger Radiator
may be necessary (contact your aircraft manufacturer or the design organization).
The content of anti-freeze and corrosion protection may be reduced to 40 % to
improve cooling performance
Dust protection of engines out of operation
Close exhaust pipe, crankcase ventilation, and induction air filter with a
dustproof sealing.
Corrosion protection of engines out of operation
See section 8.18 for instructions.
Maintenance hints:
Air filter: Check daily and clean or replace as necessary.
Drive belts: Check drive belt tension daily. If wear is evident, replace drive belt.
Radiators: Check daily for erosion wear.
