Bilateral agreements facilitate the reciprocal airworthiness certification of civil aeronautical products imported/exported between two signatory countries. A Bilateral Airworthiness Agreement ( BAA ) or Bilateral Aviation Safety Agreement ( BASA ) with Implementation Procedures for Airworthiness ( IPA ) provides for airworthiness technical cooperation between the FAA and its counterpart civil aviation authorities.
Bilateral Airworthiness Agreements are executive agreements concluded prior to 1996 through an exchange of diplomatic notes between the U.S. Department of State and its foreign counterpart based on FAA technical recommendations. (Note: The U.S. no longer concludes Bilateral Airworthiness Agreements.)
In addition to airworthiness certification, Bilateral Aviation Safety Agreements provide for bilateral cooperation in a variety of aviation areas, including maintenance, flight operations, and environmental certification. For aircraft certification, an additional document, an Implementation Procedures for Airworthiness, is developed to address specific areas such as design approvals, production activities, export airworthiness approval, post-design approval activities, and technical cooperation.
Implementation Procedures for Airworthiness ( IPA ) are procedural documents authorized by the BASA Executive Agreement for design approval, production activities, export airworthiness approvals, post-design approval activities and technical assistance between authorities. This document defines the scope for civil aeronautical products and parts eligible for import into the U.S. and the counterpart BASA signatory country. It further defines the interface requirements and procedures between the authorities for validation, import and continued support of those civil aeronautical products and articles.
Technical Implementation Procedures ( TIP ) has the same purpose as an IPA . The difference is that whereas an IPA contains the implementation procedures for a BASA between the U.S. and another sovereign State, the TIP contains the implementation procedures for the Agreement between the U.S. and the European Union ( EU ) which represents many sovereign States. As the EU does not have the authority to administer all of the procedures that are included in an IPA , the TIP includes added procedures detailing where the Sovereign States represented in the EU retain limited responsibility.
Schedule of Implementation Procedures ( SIP ) is the procedural document, similar to an IPA , that is associated with some BAAs . It facilitates the approval process for aircraft and other aeronautical products being imported or exported between the U.S. and a foreign country.
Management Plans are working-level documents that prescribe detailed methods for achieving a technical process derived from an activity stated in a BA or Arrangement. Management Plans define the roles and responsibilities needed for coordination of activities stated in the BA or an established Arrangement. The content and duration of a Management Plan are prescribed by the requirement being expanded upon and are linked to the BA or Arrangement function that it supports. Because it is important to consider each Authority's needs and how the FAA will accommodate and document updates, Management Plans must include a section to address revisions. Management Plans are mutually agreed upon by the FAA and the CAA .
Working Procedures are a type of arrangement entered into with a foreign CAA with which the FAA has not entered a bilateral agreement. They are used to define the methods through which the FAA 's Aircraft Certification Service can support another State in approving aeronautical products and articles being exported from the United States to that State.
Special Import Requirements is a document submitted to the FAA by the CAA of the importing State or jurisdiction that contains importing requirements. These documents are contained in Appendix 2 of AC 21-2.
