I have no specific knowledge of Rotax turbo charged engines.

If you suspect that the turbine bearings are failing/damaged.

In land based turbines - assuming no damage to turbine blades and housing - bearings are replaceable. Call your local turbo charging specialists.

F3 is type certified engine, so we have to have original turbo with form.

So do your "type certified" rules allow a LAIM to replace or oversee the replacement of bearings (assuming that's a possible option)?

I would assume that if a LAIM is permitted to do the work he/she would have to use certified parts supplied/approved by Rotax .

You did say you were looking for options (due to long parts supply problems) to replacement of the whole turbo charger.

We found new one from France, coming on next monday:-)

New turbo works perfectly. It can be seen from the log that the waste gate does not have to be completely closed to get full pressure.

TCU-log is the only real troubleshooting tool
