Description
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.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.
