Since we are talking so much about differences in aircraft configuration, is there an FAA database that would tell which STC's, mods and certifications that this Lear would/should have?
Our pilot certificates and medicals are online for a prospective employer or pax to check, is there something similar for GA aircraft maintenance records?
Over on the part 121 side it seems to me that the feds have been increasingly obsessed with documentation. A missing signature or piece of paper that would formerly be handled with a sticky note from a secretary is now self-reported to the feds for a possible letter or worse.
