Narrative:

I wrote up aircraft X for an autopilot disengaging in flight and stiff ailerons. We left rvsm airspace due to the autopilot malfunction. Ailerons resumed normal control forces descending into the 20's. As we had full controllability of the aircraft I view this as a non-reportable NTSB event.
