Lycoming O-435-C1

PMA parts · 575

Current parts manufacturer approvals (PMA): parts the FAA has approved companies to make as replacements or modifications. Each record lists its models as free text; OpenAirDocs matched them to this engine model on its data sheet, so check the FAA record before relying on it. Newest first.

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-228')
    AND len(list_intersect(tcds_models, ['O-435-C1 (O-435-11)'])) > 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.
