STCs that may be installed · 103

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

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.
