Thanks for the info.
You asked, "And you are a Challenger pilot and do not know this?? You never look at your maintenance log books?"
Is this information found in maintenance log books?
information you listed: "FAA registered A/C have to be maintained by an FAA certified repair station. It can be a foreign station that passes a yearly FAA inspection to make sure they are meeting the required standards and are granted a Foreign Repair Station certificate."
Seems that would be found in the FAA maintenance regulations, right?
