## About this tender

Active Control Structural Response (ASCR) Controller Obsolescence, to address ACSR installed on the Merlin Mk4/4a, as it had been identified that only the Mk4/4A would be modified and that the existing ACSR Controllers would be used to support the Merlin Mk2 fleet, therefore there is no commonality between the Merlin Mk4/4A fleet and the Merlin Mk2; the modification does not allow fitment of the existing ACSR Controller once an aircraft has been modified.

## CPV classification
