Key Takeaways:

  • The final rule for the Modernization of Special Airworthiness Certification (MOSAIC) is now expected to be announced in early to mid-2025, contrary to earlier hopes of a July 2024 announcement at EAA AirVenture.
  • Reasons for the delay include the tight schedule following the NPRM comment period closure, a necessary 30-day reopening of comments in February, and potential government resource allocation towards the upcoming election.
  • The MOSAIC rule's objective is to reduce certification burdens for new and legacy recreational aircraft while simultaneously enhancing safety through the integration of new technology.

The final rule on the Modernization of Special Airworthiness Certification (MOSAIC) is now expected sometime in 2025.

When the comment period closed for the MOSAIC Notice of Proposed Rulemaking (NPRM) in January, it was suggested that the final rule might be announced at EAA AirVenture in Oshkosh, Wisconsin, in late July, but that is no longer the expectation.
