Most of the interior sidewalls and carpet are held in place by velcro. The side panel velcro is removed from the side panel pieces and attached to the aircraft aluminum based on the position of the corresponding velcro sewn onto the interior pieces. Carpeting is installed by leaving the velcro attached to the carpeting, removing the velcro adhesive backing and positioning the carpet in place. Control stick boots were also installed. The left seat was installed, but will be removed to allow access to the baggage compartment for interior installation. Workmanship from Flight Line Interiors is outstanding.
