Approved for this aircraft’s airframe or engine model. The registry doesn’t record which STCs an aircraft has; its records do. In force first, then newest.

Query with SQL
duckdb -csv -c "SELECT m.matched_by, s.stc_number, s.description, s.holder, s.status, s.status_date, m.matched_model
  FROM (
    SELECT stc_number, min(side) AS side, arg_min(matched_by, side) AS matched_by, arg_min(matched_model, side) AS matched_model
    FROM (SELECT stc_number, 1 AS side, 'airframe' AS matched_by, matched_model FROM 'https://openairdocs.org/data/latest/faa_aircraft_model_stc.parquet' WHERE aircraft_model_code = '3022037')
    GROUP BY stc_number
  ) m JOIN 'https://openairdocs.org/data/latest/faa_stc.parquet' s USING (stc_number)
  ORDER BY m.side, s.status = 'Current' DESC, s.status_date DESC, s.stc_number"

Prints the whole list as CSV. It reads the release’s Parquet files over HTTPS, so there’s nothing to download first. Install DuckDB to run it.
