Hi Phil,
It maps out like this for a run-out 114/A:
Option 1:
Send existing engine for overhaul.
In April, AirPower was quoting $56K and 12-13 months turn around time.
Field overhaul might be cheaper but still might get stuck on parts leadtimes.
OH expectation is 2000 hours till TBO. Engine cost $28 per hour.
Hard to buy a plane on this plan, because can't fly it for a year.
Option 2:
Install serviceable engine like the one I am offering for $25K.
Sell existing core engine for $5K (may take a while).
Expectation is 800 hours remaining till TBO. Engine cost $25 per hour.
Expect be flying on the new engine within several weeks.
Installation costs expected similar.
