Murphy’s law: now sitting in Tromsø, waiting for the commercial flight (back up) and beautiful CAVOK/
perfect conditions for flying
Damn typical….
What went wrong with the engine?
Mechanics suspect turbo.
I had all indications green but degrading speed. Looked for every issue possible (before turning back which was a mistake) then at some point couldn’t get more than 70% indicated. Actual power likely 25% or so (going same speed as with engine feathered), but fuel flow etc still nominal.
I’ll post when know more, probably on a I learnt thread
For those flying DA42s, 115 kts with both throttles full forward at some point on the way back (about 1h flying until over land).
