Are you ROTAX Certified?
I'm certified at the ROTAX Maintenance level. Practically speaking, this means I can help you with your oil change and perform your annual condition inspection.
While ROTAX engines aren't especially complex, they are still a bit of a novelty in the GA world and I simply don't have much exposure to them. If you have a specific problem and/or squawk, you're better off taking it to someone that specializes in these engines.
If your ROTAX powered S-LSA is running and flying awesomely, then yes, I am qualified to sign off your condition inspection without voiding your ROTAX warranty.
