I just had the flight control system rerigged to factory settings in hopes of correcting "leaning" yokes. On the ground, it appears rigged perfectly, but in the air, there's some issues. Looking for suggestions.

Verified the plane is flying coordinated with a yaw string. Ball centered. Left aileron is up quite noticeably. Right aileron down a little. Yokes lean left. See pics below.

If I set the autopilot, I can trim the ailerons to be even, but it takes almost all available trim and slows the plane down a few knots.

Also, with the autopilot engaged, I can add rudder trim until the ailerons are neutral, but the plane is flying in a pretty good bank, maintaining altitude, yet is about 6 knots faster.

Anyone know what could be going on? Or a rig magician?

Is the right wing much heavier? The fuel gauge says it might be.

If you are near Dallas go see John Efinger, just google him. Cessna rigging expert.

It pretty much looks like this no matter the loading.

I think it might just be the airframe.

While your RPM show the same for both engines, the throttles are noticeable different in the picture, asymmetric thrust would be a thought?

Take it to John as others have suggested, the aircraft needs to be sorted out

My money is on asymmetric thrust. Big throttle split and the right MP is still low (I can't see the right fuel flow). Best guess - right engine isn't making the power the left is causing a yaw to the right. The real Question is why??? Best advice you've gotten is to get it sorted asap before the problem reveals itself at an inconvenient time.

It's not a thrust issue. The throttle cable just got replaced and the adjustment is wrong. A different story.

It flies the same at idle power.

This is nothing new, it's been flying this way for at least a year. Probably flew that way before I owned it

I have the same issue, I asked our local shop to sort it but it still does it. Seems like it's costing us at least a few knots. I posted picks over on TTCF. Has nothing to do with split throttles, etc.

I believe these engines are canted a bit more than usual for some vibration problem, not sure if that is related to any of this. These two photos were taken seconds apart, both ailerons up, one substantially so. As far as I can tell, that should never even be possible. I don't think there is that much slop in the cables even with the wings under load. I know some experimentals do intentionally put both ailerons up because they're using an airfoil that is easy to build and then modifying it with the ailerons but presumably Cessna engineering would not do that.

Shouldn't matter but this was at FL 210 / 161IAS 222TAS

If both ailerons are up the same amount, that can be easily fixed and the plane should still fly wings level. But the travels up and down need to be checked, and if they are out, that will require a bit of work. If, on the ground, the ailerons are neutral and the yoke is centered, but airborne the yoke is to the left, the left aileron is up and the right aileron is down, that is likely going to require more than a little bit to figure it out. The possibilities are too many to troubleshoot over the internet.

Well, if the left throttle is equivalent to the right one; and the right one is WOT; then it must be hard to shut down the left one.....or

the left one is partial throttle and the right one cant be pulled back to ICO.

Also both props are running at 2300 rpm and the levers are almost to the feather detent.

Man, your quadrant needs some work.

It's not difficult nor time consuming and may help straighten out the rest of your rigging issues. You can cure your throttle issues in about 10 minutes. Props will take longer.

The fuel difference is only 5 gallons (30 lbs) so no biggie/

Trying to cure this with rudder trim is where the speed loss is. Its easier to add fuel to your left auxiliary and fly straight than crab along in cruise. The ailerons will be slightly deflected, but that's not where the drag is. Its in the Fuselage.

What settings are you using to see 222TAS in a 340?

What about the flaps and gear doors?

Another thing to consider is the tail feathers and one of the rigging experts will look at that, too.
