I must admit that the simplicity of a fixed pitch prop is appealing, but I'm afraid I may have gotten used to the in-flight adjustable's ability to optimize for climb and cruise.

In past years I've had that happen one other time, plus two failed electric pitch motors. Fortuntately the failure mode is always the same - pitch is stuck where you last had it.

Arplast now say that there is no limited life. Laetitia, whom I have spoken to briefly in the past, provided some additional maintenance information. Unfortunately it is a .jpg copy and in French, so it is not easy to translate automatically. As far as I can determine there is nothing particularly new about the information, so provided we continue to grease the bearings and lead screw it should all be OK. I will send the .jpg information separately. Maybe your French language skills are better than mine, so if you see anything useful perhaps you can advise. Brian.
