Engine failure
Yes, front engine feathered itself on CAVU day by myself with about 120 gls fuel in 1976 337G, normally aspirated. After I settled down, I decided to continue to my destination - my home field where my mechanic was. Flat Mississippi Delta under me and about a 45 minute flight after I lost about 20 knots in speed.
A gasket blew in the prop governor causing the prop to feather. Most props fail to low pitch (high RPM) when they fail but the IO360 fails to the feather position. Replaced the govenor with another one and didn't lose a thing - all in warranty - the goveror that failed had about 25 hours on it.
I don't know if I would call it a non-event because it raises one's adrenalin level considerably and I kept my eye on a strip within gliding range all the way back!
That's 4th engine failure in 46 years, 5000 hrs; three of them the same IO-360 engine (2 in 337's and one in a Seneca.)
