Hi Shoeman,

we got a positive sample! And know a couple more with positives samples.

I indirectly know of one DA50 owner and they are undergoing engine exchange after positive sample.

Positive in the sense of a good outcome, meaning no further action necessary ?

Positive in the sense of an abnormal high amount of copper in the oil after ~75 hrs. We‘ll probably get a new engine.

Interesting to know the cause (bad batch of bearings?) and how it's solved on replacement engines.

[Shoeman]

I got good results back in 036 but 037 needs a new engine. I am not sure if they know yet whether it is faulty parts or faulty installation that causes the problem

[Wilhelm]

Do you happen to know how many hours these engines had ?

[Shoeman]

036 had 142 not sure on 037

What parts in the engine are copper?
