RV-10 AOG TBC (Tuba City AZ)

[woxofswa]

Had an inflight failure of RV10 MT prop governor while enroute from SLC to Mesa AZ. Case breach of governor resulting in oil loss and prop driving to coarse pitch.

Good news TBC was available for quick divert. Bad news TBC is TBC and there is nothing here but a runway.

Throwing this out that perhaps someone has an MT P680-3 sitting on a shelf in UT or AZ that we can acquire faster than we will be able to get one shipped as luck would have it our first day AOG is a Sunday.

Thanks for reading. Stuff happens

Myron,
Thankfully you were able to make the diversion! I just dropped my 680-3 in the mail to MT in Floriday for them to perform the SB. Do you know if yours was covered by the SB?

Hmmm, this sounds similar to what Todd Stovall experienced. I hope this isn't a start of a trend.

Can't help with the repair or anything, but if we can help with transportation or anything, Tuba is not that far from Flagstaff.

You wrote course (sic) pitch but did you mean fine pitch? Was there an engine overspeed?

I have a pcu5000x you can use if we can figure a way to get it to you from Coolidge AZ

No, sorry, I meant coarse pitch. (Stupid spell checker). In flight all
I knew was sudden significant loss of thrust (over eastern corridor of Grand Canyon) and RPM was about 500 below normal for throttle setting, and moving prop control did nothing. Very glad I didn't continue, (FLG) because when I landed, oil was dripping out of cowl outlet. I had lost about 1-1.5 quarts over a ten minute or so period. Engine oil pressure never got low nor did temp get high, but certainly would have if I had continued. On landing inspection a tiny flap of case material (Still attached) had opened up on PG case side.

Rescue team on the way. What a beautiful community we are blessed to be part of. Thanks everyone.

If tools, logistics... etc. rear their ugly head... I can fly there today from Prescott. Have tools, oil etc. cell: 928 273 nine three three one. Nick

Home now thanks to the efforts of a couple of the brotherhoods finest who flew me up a new Lyc PG donated by a Bearhawk project.

The failure turned out to be an uncontained internal failure that punched a part (gear tooth?) through the PG sidewall spewing oil out of the case and losing pressure on the side that causes the pitch to go coarse.

Many phone calls tomorrow.

If your PG starts acting goofy assume you are losing oil. As bad as Tuba City turned out to be, continuing on would have meant highway, brush, or forest.

Thanks to the many offers of help and support. It is an awful
Feeling to be stuck. This avocation is not about airplanes as much as it is about people and friends.
