The aircraft was registered to Professional Aviation Group LLC in Apr 2008. It's possible that it was going to be leased to a new start-up airline called Royal Air which may have not got off the ground. I cannot find any data on this Royal Air. US registration cancelled 15 Dec 2008. It became HI875 with SAP (Servicios Aereos Profesionales). To SOA Holdings LLC Jan 2018 as N875AZ.
