About 10 min after taking off from Owatonna I noticed my oil pressure on the rear engine dropping, and then bouncing from just above 0 to the bottom of the green line. I made the call to shut off the rear engine and secure it.

The flight from that point back to Austin was about 12 min. It was a quieter 12 min than normal with a lower airspeed but tracking solidly at 3500'. Greased it in back at Austin. I felt totally comfortable and didnt think twice about my actions. The plane flew hands off and going through the check list was a piece of cake.

Something let lose in the oil system, had oil everywhere inside the cowling and on the outside of the plane.

As they say, bad things come in 3's:

1. loss of an engine
2. The tremendous oil loss was on the main wheels. After touchdown, and on the roll out and breaking, the tire rotated on the wheel shearing off the valve stem and giving me a flat tire which is interesting at 50 mph- had to put on a loaner on the taxiway to get it to the shop
3. 5 planes in the shop ahead of me.....3 of which have no engines. Mechanic said I will be grounded till around February......

The single engine flying was amazing and actually pumped me up about the abilities of the Skymasters. The whole ordeal was a nonevent and I struggled way more with the flat tire than the loss of the engine. I love them!!
Tom - super glad to hear it worked out to be a "non-event". I have a T337C and had an eerily similar situation. Turns out that it was the little oil feed line going into the top of the turbo on the rear engine. You might check to see if yours is cracked or has a hairline fracture. If so, voila - less downtime. BUT, do not just replace it with the same part number. The newer model T and P planes came with a stronger more reinforced feed oil line to the turbo. It is legal to upgrade to that part....also make sure you change out the check valve if you replace that line, with the newer check valve.

In any case - fantastic news that all is well. Better to be on the ground wishing you were in the air, than in the air wishing you were on the ground : )
