payable

Title and airworthiness due-diligence verdict for a US-registered aircraft from the public FAA Aircraft Registry. Give a tail number or serial and get a 0-100 title risk score, a low, medium, high or critical rating, a clear_to_transact flag, per-dimension signals, reasons and the cited registry fields. Deterministic, no LLM. A diligence signal, not a certified title search.
