The reporter in the right seat had to recover from a 60 degree pitch up on final approach with the throw over yoke oriented to the left seat. The pitch up was the result of the autoplt being on or turned on in error.

Narrative:
The pilot on final accidentally turned on autoplt and altitude mode. It is a single yoke bonanza with dual rudder control. I was in the right seat. The pilot told me to take over and let go of the yoke. The aircraft went to a 60 degree nose high attitude at a low power setting. When I took the controls, I turned off autoplt, added full power and recovered from the stall and landed on runway 28. All this was a result of the autoplt inadvertently being turned on or not being turned off, and a single yoke which made it hard to tell the amount of forward pressure that the pilot was putting on the yoke to maintain level flight.

Title: THE RPTR IN THE R SEAT HAD TO RECOVER FROM A 60 DEG PITCH UP ON FINAL APCH WITH THE THROW OVER YOKE ORIENTED TO THE L SEAT. THE PITCH UP WAS THE RESULT OF THE AUTOPLT BEING ON OR TURNED ON IN ERROR.
Narrative: THE PLT ON FINAL ACCIDENTALLY TURNED ON AUTOPLT AND ALT MODE. IT IS A SINGLE YOKE BONANZA WITH DUAL RUDDER CTL. I WAS IN THE R SEAT. THE PLT TOLD ME TO TAKE OVER AND LET GO OF THE YOKE. THE ACFT WENT TO A 60 DEG NOSE HIGH ATTITUDE AT A LOW PWR SETTING. WHEN I TOOK THE CTLS, I TURNED OFF AUTOPLT, ADDED FULL PWR AND RECOVERED FROM THE STALL AND LANDED ON RWY 28. ALL THIS WAS A RESULT OF THE AUTOPLT INADVERTENTLY BEING TURNED ON OR NOT BEING TURNED OFF, AND A SINGLE YOKE WHICH MADE IT HARD TO TELL THE AMOUNT OF FORWARD PRESSURE THAT THE PLT WAS PUTTING ON THE YOKE TO MAINTAIN LEVEL FLT.
