Feathering on power off. GTSIO

[corsario28]

Hi anyone has experienced a slowly feathering when turning off a GTSIO engine? I heard a metallic tickling inside the prop cone after shutdown, I felt it by putting my hand on it and my other hand on the prop to feel how it slowly moving to feather. I can estart the engine ans it will go to full forward automatically. Any guess?

I'll try to help you. What is your prop model and aircraft?

Not the OP, but my guess is its a Cessna 421B or Cessna 421C. Those are essentially the only ones running the GTSIO engine - unless you count the new Tecnam P2012 of which they are the only ones running and not sure if any GTSIO engines have been delivered in that configuration.
