Cost of Overhaul

[checkride]

Anyone got an idea of the cost of overhauling a 912 ULS . Engine still runs sweet but TBO. BB all 78.

Why overhaul? I know of a uls that has never been opened and going for 3600hrs
and purring like a kitten.

There is no law that you have to overhaul NTC engine after TBO hours. It is flown
"On condition"

You have this in writing somewhere

I might be confusing tbo with 12 year compulsary overhaul.
Will get facts and get back to you

This is for 2 stroke. I do believe somewhere there is a similar
document for 4 stroke. I will find and let u know.

Do someone recently overhauled a Rotax 912 ul or 912 uls, and at what estimate can I work on? Which place in SA specializes in overhauls of Rotax engines?
