In my case, the cause turned out to be slack cable tension between my pitch servo and elevator pushrod. I could feel the play in the pitch axis by engaging my A/P on the ground and finding that I could move my stick slightly back and forth rather than it being tight as it should have been. The cable was tight when we installed it, so I can only assume it relaxed a bit once I started flying. I tightened the turnbuckles to reestablish the proper tension and everything's been fine ever since. Odd that yours would be OK for three years before exhibiting these symptoms. Skip Slater N540ES
