I have a 1981 Archer II with original auto pilot. The system works on ground when adjusting the dg bug. But in the air, she just keeps rolling over past the assigned heading bug. Any thoughts? Brad.

Sounds like you probably have a century II autopilot and someone has switched out the attitude indicator for a non autopilot version. When I bought my airplane this exact thing happened to me. So the autopilot was essentially useless. Ended up having the avionics shop look at it and he diagnosed it pretty quickly.

If the connector on the attitude gyro has been removed or a wire has been pulled out from a contact, that will cause an inop autopilot.

This is the "planes for sale" forum. Sounds like you have a defective autopilot. Very dangerous. I would sell the plane if I were you. Coincidentally, I happen to be in the market for an Archer II. I think you need to sell it to me, to avoid inadvertently turning the autopilot on and crashing the plane. ;)
