SCHEDULE OF AIRWORTHINESS DIRECTIVES

Background: The FAA has received reports indicating that, while operating in icing conditions or when ice is present on the wings, some Cessna 560 aeroplanes have experienced uncommanded roll at (or slightly higher than) the speed at which the stall warning system is activated.

This Directive requires amendment of the AFM and modification of the stall warning system angle-of-attack computer. These measures are intended to decrease the likelihood of uncommanded roll during approach and landing when residual ice is present or can be expected.
