MT P-860 Prop gov failure

[tsts4]

So I was out flying a practice approach and as I reached the MAP and poured the coals on I heard a pop and the RPMs redlined. I immediately pulled power and discovered I had zero prop control. As we were only 15 miles from home, and all other engine parameters were green I opted to limp back at 14-15", 2500-2600 rpm which gave about 90 KTS. After getting home safely we pulled the cowl and discovered that piece of the prop gov case, approx 1/16" wide and 1/2 " long had peeled back for some reason (obviously something internal disintegrated) and spewed oil over the bottom cowl.

Anyone ever seen a failure like this?

Ouch. That is a new one to me. Glad it ended well.

Well I definitely had an overspeed because of this and it's going to require the full monty tear down and inspection IAW Lycoming SB 369L.

The question is do I have a local guy do it or ship it to an engine shop like BPE who built it to begin with?

 

[Let'sgoflying!]

will you get a report on the governor internals?

will you get a report on the governor internals?

I hope so. MT is shipping me an exchange unit and I'm supposed to ship them mine.

That is the exact model in my RV-10. I purchased mine in 2011.
