Bilateral Aviation Safety Agreements

Bilateral Aviation Safety Agreements (BASA) provide for airworthiness technical cooperation between the FAA and other civil aviation authorities.

BASA's cover a variety of aviation areas including aircraft maintenance, flight operations, and environmental certification.

Where aircraft certification is involved, an additional document called the Implementation Procedures for Airworthiness (IPA) is developed.

The IPA provides guidelines related to specific activities such as design approvals, repair data approvals, production approvals, export airworthiness approvals, post design activities and other areas of technical cooperation.
