What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On final approach crew encountered an uncommanded roll to the left. They pulled roll circuit breakers maintained aircraft control and made a normal landing. Later it was found something had been spilled in the autopilot/trim area of pedestal controls which had caused the problem. Parts were removed and replaced as necessary and system checked. Chief pilot put out a bulletin to not place spillable drink containers anywhere near this area.
