Great to read about your flying, sorry to hear the engine conked out! You sending it to Brian at Arkansas Turbine? He's great guy and will take care of it without taking you to the cleaners.

Yes, I've missed locking them on stops at shutdown a few times, but thankfully on mine it's really easy to get the pumps to lock them back. I'm sure it's similar on yours.

Hope it's not too expensive!

And -1's are getting a little scarce, so prob not a bad idea if you can find a backup engine.

Adam, yes I spoke to Brian, he does have a used -2 engine that can be converted should there be serious issues with this one.

When I had my F model, I bought some Merlin engines just for the peace of mind.

Used to be plenty when all the crop dusters ran them, but they've ran through most of them by now.

There is a -6 STC out there owned by Standard Aero for F models.

Essentially the plane can become a K model except for ACM and some interior vent differences.

Hilgard, sorry for your misfortune. We've had an issue with an engine seal on our Marquise and were surprised by how reasonable the repair was. Hardest part was coordinating logistics to pull the engine and send it in.

Nice write up Hilgard. Thanks for posting! That photo looks like you left it in Fargo? I always found the folks at Fargo Jet Center very helpful.

Thanks for the writeup Hilgard - Based on numerous posts from fellow BTrs, I'm not alone in my persistent fantasizing about an MU2 to replace my piston-twin.

Please continue to keep us posted on your MU2 "adventure" - Hoping the recent turbine issue proves to be minor....Bill

Yes, good eye. We left it at a the Jet Center initially, but now secured space in another MU2 owner's hangar to have the engine pull done on Monday.

Any updates on this, Hilgard?

I don’t have the final report yet, but so far, it looks like nothing major.

It took three weeks to organize the logistics and get the engine to the shop. They received it last Monday and ran it on the test stand several times. They could not get it to surge the way it did in flight, it seemed fine.

There is an oil leak from the compressor seal. To replace it, they had to open the engine. I spoke with the shop again today, and no damage was found.

They believe the torque sensor may need adjustment and could be malfunctioning, it was one of the items we noted for the upcoming inspection. Arkansas Turbine will send it out for bench testing. While that is being done, they will also have the prop governor and fuel control unit bench tested. It will take another 2-3 weeks to complete this since the components have to be sent out.

Meanwhile, Green Bay Aviation has removed the props for overhaul. They have about 900 hours and 18 years since their last overhaul, I thought it would be good to use this downtime to get as much maintenance as possible done.

Once we have the engine back, it will go to Green Bay Aviation in WI for its 100/200/600-hour inspection, as well as some avionics upgrades. I hope to have it back by mid-December.

Hilgard do you have "dash 1" Torque Sensors?

In our -6 airplane it was the Torque Sensor (3101726-1) that failed and left us with no high pressure fuel pump in flight and some presents in the filter.

I thought they were getting rid of most of those though.

Anyway hope you get a quick resolution.

Good question, I will find out what Torque sensors we have.

Yes Jet Air, Green Bay WI. Obviously yesterday was a long day..

Hilgard

Of course, you are in great hands with Brian and his team!
