Do you do oil analysis?
If you do the company sends you results that evaluates what is normal (at least the company I use does).
They will tell you if the results are normal or above normal.
If above normal they will typically advise you something like higher than normal- suggest re-testing at next oil change or some number of hours.
Initially at the first oil analysis they usually indicate that high ppm's may be normal in light of a new engine.
Obviously the results of the oil analysis may not be coincidental with the Rotax problems. If all gearboxes shed lots of iron due to a design flaw the average results will indicate normal.
No change. I’m going to bring it to Lockwood’s attention and see where we go from there. I’ve been assured by more than one Rotax tech that it is not a precursor to failure. I was assured a permanent fix was in the making too. Outside of that, the engine has been flawless.
I was on a 2-hour cross country yesterday and experienced the same vibration mentioned above. It didn't seem to correlate to engine rpm. More so indicated airspeed. Once it reached a certain speed, the vibration would start. When I backed off the throttle and airspeed diminished by about 8-10 kts it would stop. I was only able to reproduce the vibration at altitudes above 5,000 ft. Below 5,000, no vibration at any speed or rpm. A few times I was able to firewall the throttle and the vibration would go away. Looking forward to a fix from Rotax.
