yr right, as you are no doubt very aware, there are only a small handful of aircraft engine re-builders here in Australia. Of this small handful, the number of outstanding organisations can be counted on one hand with fingers to spare.
I attended an APS course (
see this thread) and was heartened to see that the manager of one of these outstanding establishments was a presenter and the manager of another was a participant. That is, almost 100% of the best aircraft engine builders in Australia were in attendance!
Thank you again for your input, it is great that an engineer takes time to read and post on this forum. If you want to know which engine re-builders were at the course, feel free to PM me.
