Narrative:
While on route the weather was deteriorating to 600 feet overcast and 2 miles. I was reviewing the approach options for the airport and when I went back to heads up the autopilot had disengaged and was 7 degrees nose down and 45 degrees bank to the right. After recovering from the unusual attitude I was 1 mile south of course and 500 feet below assigned altitude. By the time I had finished accessing the failure; getting back on course I was already on a different frequency and had failed to report the deviation to the controlling facility.
