If you want to duplicate ADs (for example, for recurring inspections) you can do so by clicking on "Duplicate Multiple ADs" option within the "Action" button on the report header:
For example, certain Cessnas have a recurring inspections regarding exhaust system corrosion (AD 2000-01-16) which requires recurring inspections. To duplicate this AD (as per inspections and MOCs), check the box next to the AD you want to duplicate and then click "Add to Duplicates List".
You'll need to confirm that you want to duplicate the selected AD - hit "Duplicate Checked ADs "again to finish the process and you will see the AD duplicated.
Repeat as many times as required.
