FAA AD Search

FAA AD Search is a free, searchable index designed to help aircraft owners, mechanics, and maintenance shops find publicly available FAA Airworthiness Directives. Users can look up directives by aircraft registration number, aircraft make and model, keyword, or manufacturer, and browse documents related to aircraft, engines, and propellers. The site provides direct links to official source documents and features recently issued directives, emergency notices, and searchable historical records.

Its index includes thousands of unique AD identifiers and source documents, alongside annual issuance counts and a history and methodology overview. Additional resources include downloadable datasets, a sitemap, and REST API documentation, making the collection useful for both individual searches and broader data access. The site states that its records are actively being ingested and may be incomplete, so results should not be relied upon without verification. FAA AD Search is not affiliated with or endorsed by the FAA and advises users to confirm information with official sources. It describes its data as sourced from publicly available FAA records.
