A bill to provide for updates to the Federal Aviation Administration type certification process to support development of new and novel technologies, and for other purposes.

This bill (S 3866) updates the Federal Aviation Administration’s (FAA) aircraft type certification process to accelerate approval for new aviation technologies like air taxis and advanced air mobility vehicles. It directly affects aircraft manufacturers, FAA staff, and infrastructure providers (such as vertiport operators) by requiring the FAA to publish clear timelines for certification milestones and establish standardized criteria for when the FAA issues formal "issue papers" about safety concerns. Key mechanisms include mandating a public transparency plan within 180 days, setting standard expected timelines for key certification steps (like responses to industry requests), and revising delegation rules to improve efficiency while maintaining safety. The bill aims to reduce delays for innovative aircraft without compromising safety standards, focusing on predictable processes for emerging technologies.
