I'm sure if you called Lear Customer Support they'd be happy to help you find it in their data base. Worth a shot anyway...You can also search this web site...
Scan down, they have a downloadable list for Learjets. I searched it, but didn't see N805LJ.. I saw 804LJ and 806LJ. If you have the s/n that is a BIG help.
