A quick query from “Down Under”. I am up to building the hydraulic system for my Lancair 360, and need to purchase some hydraulic hose for the gear retract system. I understand the system theoretically operates at about 1500 PSI. However I have spoken to someone with experience on a similar aircraft, and he said that he has observed pressures over 2000 PSI, due to the heat soak phenomenon previously discussed on the LML.

 

My question is, what pressure hose have others used in their aircraft? Do you have any suggestions or useful comments about building this system?

 

Thanks in anticipation.
