Oil tank access panel Access panel removed
This picture shows the principle of the oil system, as shown in the Rotax handbook. For this
aircraft a thermostat is included within the oil system for better control of the oil temperature,
see the line diagram below.
Only the oil tank is accessible without removing the upper engine cover, other than visual
checks through the cooling apertures. To remove the engine cover, undo all the camlok
fasteners around the edge of the cowl. Pull the four around the rear mast cowl out as far as
possible. Then ‘wiggle’ the cowl to detach from the lower cowls, and lift it off. Refitment is the
reverse process.
