Executive Summary:The aircraft suffered a lateral flight control restriction as a result of loose insulation material becoming trapped in the aileron control circuit. The crew carried out the memory items for the 'AILERON JAM OR UNCOMMANDED ROLL' checklist, but did not realise that in addition to pulling the Aileron Disconnect Handle there was also a need to apply a breakout force to the control wheel to achieve the disconnect. One safety recommendation has been made.
