The Certification Authorities for Transport Airplanes (CATA) is a group of aircraft certification management representatives from the National Civil Aviation Agency of Brazil (ANAC), European Union Aviation Safety Agency (EASA), Federal Aviation Authority (FAA) of USA, and Transport Canada Civil Aviation (TCCA).
The CATA is tasked to identify and pursue, through collaborative activity, certification policy and guidance harmonization opportunities.
CATA harmonization decisions
CATA harmonization decisions are documented in finalized CATA Worklist Item (CWI) forms, signed by the CATA principals from all four authorities.
As with any policy, if a CATA member-authority becomes aware of circumstances that make it apparent that following the documented approach would not result in compliance with the member-authority's applicable airworthiness standards, then the terms of the CATA document are non-binding and the member-authority may require additional substantiation or design changes as a basis for determining compliance. Compliance approaches described in CATA decision documents are also non-binding for applicants. Applicants are free to propose alternative approaches.
CATA Worklist Item (CWI) Decision Documents
The CWI can all be found on the FAA website (English only). Each link to the FAA hosted CWI is embedded in the following table.
Note: The following documents are signed international agreements that are available in English only.
