Query with SQL
duckdb -csv -c "SELECT s.stc_number, s.description, s.holder, s.status, s.status_date, m.matched_model
FROM (
SELECT stc_number, min(matched_model) AS matched_model
FROM 'https://openairdocs.org/data/latest/faa_aircraft_model_stc.parquet'
WHERE aircraft_model_code IN ('1181102')
GROUP BY stc_number
) m JOIN 'https://openairdocs.org/data/latest/faa_stc.parquet' s USING (stc_number)
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.
