I used to own a PFA aircraft and did all my own work.
At the moment I am flying a rented PA28, I was collecting one of the school's aircraft from the hangar the other day and it was like the "secret service". The engineers, won't talk about their work, I ask about various things that I noticed wrong with the a/c on previous flights, and was told "we know all about that" (they did not).
I now have lost confidence in this facility as I feel they just "bull!!!!" the pilots.
I will be buying again soon and I don't think I will be going there.
