I don't know specifically about the Rotax, but generally there are service limits on the engine that will be checked at 100 hour or annual intervals.
Those will typically cover oil consumption, compression checks etc and anything mandated by the manufacturer.

In practical terms it depends on what the engine is fitted to - whether it is CofA or permit, and if on a permit whether the permit is administered by the LAA, BMAA or the CAA. They all have different rules.

In the UK, extension of up to 20% is allowed on condition for public transport or aerial work. Beyond that only for private use ( exception allowed for glider tugs)
Covered by CAP 747 GR 24

Is it legal (in EASA country) to use an on condition engine...
...commercially, for example in a rental plane?
