I just had a complete overhaul of my NA SR 22 by Bill Cunningham at Powermasters. One of the things I learned is shops play games with what’s included and what’s not. Oh, you wanted your starter overhauled? Your oil cooler, alternator? Make sure you understand what’s included and what isn’t BEFORE you drop off your plane.
Bill was the most expensive at $46,500 for a complete overhaul but he included accessories other shops charged extra for. I added a prop governor overhaul and paid for needed baffling upgrades and a few other items.
Out the door was just under $60k for everything. Bill has a reputation for doing the little things that can make a big difference over time and that’s why I went with him.
I dropped the plane off with 2,980 hours on the hobbs. No top, no overhaul, just one cylinder that needed replacement three years ago from excessive valve guide wear. I flew ROP for the first 200-300 hours before going to LOP and typically run around 2500 rpm.
Bill builds his engines to run very smooth LOP. Plane was in his shop about six weeks, very busy place. So far it’s running like a champ.
