So last year I was chasing down what seemed like excessive vibrations.
In the process, I had the propeller installation looked at, as I suspected it had been improperly re-installed previously after working on an unrelated problem.
I also found out about dynamic balancing.
So, with those two pieces of information, I went to the local guy that does dynamic prop balancing and said:
- Could you check whether my prop is properly installed?
- If not, remove and re-install properly
- Then dynamically balance it.
He ended up removing it, re-installing it, and balancing it. Great.
Turns out he did it wrong too (!@#%@#%).
As a matter of principle, I may go chase after him to fix his work, but still I'm curious ... how big a deal is it to have a propeller not installed exactly as per the MM? I mean everything runs great otherwise, and if it wasn't for the fact I'm a stickler for details and have a copy of the MM myself to check after the mechanics, no one would be the wiser really.
The prop is due in two years I think, I may just wait, the logistics of getting the plane in to see the guy, and arguing about it, might not be worth it, if it's otherwise not that big a deal.
Thoughts?
