The TIO-540-AF1B is a unique beast, and quite pricey. Although I am just a little past 1,000 hours since overhaul, I am looking down the road and planning financially. I have found that there is a dramatic difference in the price between having a good shop preform the overhaul versus getting a Lycoming zero-time engine. I did a zero-time Lycoming on my C72R a few years ago and have been nothing but pleased. However, the price difference for the AF1B is exceptionally substantial. Is the zero-time engine really worth the substantial difference? I welcome any insight from others that have been down this road.
What are you looking at price difference wise? I recall that the air power factory rebuild is somewhere in the 60s. I also believe that comes with a rebuilt turbo as well? If I still own my plane when I get near overhaul I’ll probably go rebuild. From the little that I’ve heard they seem to perform very well.
It’s over $100K for a brand new one but the last person who got the factory rebuild said almost every part was brand new.
