The United States Federal Aviation Administration (FAA) and the Civil Aviation Authority of Singapore (CAAS) have signed an enhanced Bilateral Aviation Safety Agreement – Implementation Procedures for Airworthiness (BASA-IPA) on 23 September 2025. The agreement, signed by FAA Administrator Bryan Bedford and CAAS Director-General Han Kok Juan, aims to streamline the validation process for certain aircraft modification designs between the two countries.
The enhanced agreement will see the FAA recognising CAAS approvals for minor aircraft modifications, all aircraft repairs, and minor changes to article designs. This development is expected to benefit Singapore-based companies requiring US approval for their work. “This agreement underscores a significant step forward in our efforts with CAAS,” said Bedford. “By streamlining regulatory processes whilst maintaining the highest standards of safety, we’re strengthening global aviation partnerships and fostering innovation for the aerospace industry worldwide.”
Han highlighted the importance of the agreement, stating, “The expansion of the CAAS-FAA mutual recognition agreement is testament to our close partnership and the trust and confidence and marks a new milestone in Singapore-US aviation cooperation.”
The FAA and CAAS first signed a BASA-IPA in 2007. The latest enhancement follows a joint review, including site visits by the FAA to Singapore-based aviation and aerospace companies, further solidifying the collaborative efforts between the two nations.
