duckdb -csv -c "SELECT s.stc_number, s.description, s.holder, s.status, s.status_date
  FROM 'https://openairdocs.org/data/latest/faa_stc.parquet' s
  WHERE s.stc_number IN (SELECT stc_number FROM 'https://openairdocs.org/data/latest/faa_stc_model.parquet' WHERE tcds_number = 'A3SO')
  ORDER BY 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.
