Link AD or SB E/C to Existing EO E/C

If the E/C is for an Airworthiness Directive or Service Bulletin, it is often necessary to link the Airworthiness Directive or Service Bulletin E/C to an Existing Engineering Order E/C. This is done through the Engineering Control, Schedule Control tab or the Engineering Control, Schedule Controlled By tab. For more information, refer to the Engineering Control, Schedule Control Tabs subprocess.
