The liens being advertised are sold individually. However, in order to make the bidding process more manageable, the liens are divided into groups called "batches" consisting of approximately 500 liens each.
Please visit the FAA National Based Aircraft Inventory website to make sure the registry of your aircraft based location is current as it affects grant funding for Colorado Air and Space Port (CASP). CASP will soon have a form available on our website so you can update your aircraft information with us as well.
