Navigate to the workpacks page of the website for the aircraft you wish to add a workpack on. Then click on "Add a New Workpack"
Next, complete the PO Number, Description and ensure you've selected the date this workpack is being created for (this can also be in the past for retrospective additions). Use the status toggle to either keep the workpack in draft form, or to create the workpack as active and allow it to be signed off.
Now you can add any items to this workpack. Use the drop down options to filter the list, then you can start typing or simply click the empty box to view a full list. Clicking the item will add it to the workpack.
Items added to the workpack will be listed and if a mistake has been made, clicking on the bin icon will remove the item from the workpack.
Once you're happy, click save.
