Query with SQL
duckdb -csv -c "SELECT d.ad_number, d.status, d.subject, d.makes, d.models, d.effective_date FROM 'https://openairdocs.org/data/latest/faa_directive.parquet' d WHERE year(coalesce(d.effective_date, d.publication_date, d.issue_date)) = 1977 ORDER BY coalesce(d.effective_date, d.publication_date, d.issue_date) DESC, d.ad_number 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.
