Subject:   G-PTAG Wing Dolly/Jabiru 3300 Oil Cooler
Description:   

There has been a number of discussions concerning single person wing rigging/de-rigging of Europa's and stowage of the wings in covered trailers. This is my solution and it works well except the pivot could do to be another 4" towards the trailing edge.

G-PTAG survived an oil cooler fracture ( probably due to the mounting on the cowl) which showed that oil could escape without the pilot knowing. The oil cooler mounting has been reworked onto the engine with a more dedicated air duct and warm air collector manifold and since oil cooling is only needed after periods of full power the cooler circuit can be turned off for cruise. Reducing the cooler time in circuit and thereby reducing the chance of oil starvation due to oil loss. This is currently subject of PFA modification process. This method was chosen in preference to thermostat control since 5% of oil would always need to be flowing round the oil cooler circuit.
