Query with SQL
duckdb -csv -c "SELECT drs_guid, part_number, part_name, holder, pma_number, replaces_part, supplement_date, tcds_models
FROM 'https://openairdocs.org/data/latest/faa_type_certificate_pma.parquet'
WHERE tcds_number IN ('E-282')
AND len(list_intersect(tcds_models, ['501-D22C'])) > 0
ORDER BY supplement_date DESC, drs_guid DESC"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.
