NOTE: Contact AIR-400 at 9-AWA-AVS-AIR400@faa.gov for assistance when using one of these legacy Implementation Procedures for Airworthiness (IPAs) or legacy Bilateral Airworthiness Agreements (BAAs) in support of a project, and before contacting an Authority about use and effectivity of these documents.
Before the formation of EASA, the FAA had IPAs with seven EU member states. On May 5, 2011 the FAA-EASA Technical Implementation Procedures (TIP) for Airworthiness and Environmental Certification went into effect. The TIP supports the Agreement between the Government of the United States of America and the European Union on Cooperation in the Regulation of Civil Aviation Safety, which was signed in 2008. The TIP supersedes the existing IPAs for the aircraft, products, and services for which EASA has assumed responsibility as listed under the EU Basic Regulation. The legacy IPAs are still necessary when working with the National Aviation Authorities (NAAs) for products and services for which EASA has not superseded the NAAs' regulatory responsibility. Contact AIR-400 (or more specifically AIR-420) for additional clarification and support.
Similar to the legacy IPAs provided above, some older BAAs also include scope details that remain in effect. For the scope details that remain under the purview of the NAA, and where no IPA exists, these legacy BAAs remain valid:
