I contract fly a 2005 PC-12, serial # 641. Recently, my co-captain and I have had a problem (yes, we fly as a crew; company likes it that way and so do we). We ran the pusher test on the copilot side; we pressed and held the pusher interrupt and the yoke would not move the elevator. We had aileron control, but no elevator control. Now, on the pilot's side, no problem at all getting complete control of the elevator and aileron. Works just fine. We have tested it multiple times with the same results. This is a very recent (to us) development.

Every time we run the test, it passes.

Doth this be correct? Or do we have trouble.

I am not flying this week, otherwise I would have a video posted.

What say y'all?

I wish I could help but I don't know the legacy PC12's and I'm sure the system is different.

However, when I hit the pusher test button, I already have the yoke pulled out. Are you saying the yoke sticks?

Jason, yes, the yoke sticks. We have the yoke pulled out partly. Upon further research in the reference manual, the copilot side is supposed to be “heavy” and require a significant pull to move freely, but it does not move freely. We may just not be pulling hard enough.

The copilot yoke doesn't move and the pusher test doesn't push on copilot yoke side test. That's only on the pilot side.

Mikko, we get a push on the copilot side.

Did you instruct at Auburn University about fifteen years ago?

Both yokes obviously push simultaneously.

The copilot pusher test is just push the pusher interrupt button for a few seconds to get the pusher CAWS on and off again. No need to use the pusher test button.

So - Pilot side, flaps 15, blip the PCL (the AFM is not correct in this, you don't need 5psi torque, just blip the PCL. The FSI simulator needs 5psi) and push pusher test and keep depressed, hold the yoke until you get the push, depress pusher interrupt and release pusher test button until the CAWS light comes on.
Copilot side, just push the pusher interrupt for a few seconds and you get the pusher CAWS light on, and it goes off after that. Job done.

No I didn't..

Interesting... thx will try next time. :thumbup:

Mikko, thanks.

There was a Mikko T. and a Marko T. at Auburn when I was an instructor there, that’s why I asked.

There is a contact switch switch on the idle stop side of the PCL. All that’s needed is to open that contact switch to run the pusher test. If you move the PCL forward while the engine is off, you can hear it click to determine how far forward you need to move the PCL, once the pusher test button is activated the PCL can be pulled back to the idle stop. This method helps keep thrust low for those behind you.

Yep same switch that is used for gear warning horn.
AFM says 5psi, it's not correct, I don't normally even see a change in the psi when I do the pusher test.

Pilatupus drivers, I've got a question
