O-320-B3B 75 SMOH. Sterba prop. 1076 TTAF. ICOM radio. Sigtronics intercom. Garmin G3 MGL engine monitor. no transponder or encoder. I always use Cam Guard. Pmag on right side. Slick on left. Complete set of plans.

At a minimum it needs a cylinder and elevator trim actuator to fly. I wasn’t flying it enough so the #2 cylinder rusted up. It was a concern at 3 SMOH when I bought the airplane but was fine as long as I flew it regular. The last T18 entry in my logbook was in February 2021. Last completed condition inspection was March 2020. I haven’t done anything with it since I discovered the bad cylinder.

Located at F08. $15,000.

I don’t know if anyone is actually watching the forum anymore but I have a correction and an update. There is a Garmin G5, not G3, installed. And someone brought a borescope to the airplane today and we found corrosion in all 4 with #4 appearing to be worst. We were going to pull a jug to check the cam but my cylinder wrenches are MIA.

There are still a lot of good parts here. I would hate to break it down to sell the pieces. Make me an offer.
