Otto Aerospace Celebrates FAA Certification Milestone for Phantom 3500 Program
Otto Aerospace recently announced a pivotal achievement for its flagship Phantom 3500 program, which marks a substantial regulatory milestone with the completion of the G-1 Issue Paper. This milestone establishes the aircraft's Certification Basis in collaboration with the Federal Aviation Administration (FAA) under 14 CFR Part 23. The finalization of the G-1 Issue Paper is not just a bureaucratic step; it lays down a clear regulatory pathway for the type certification of this innovative aircraft.
The journey toward this accomplishment has been strategic. Otto Aerospace formally became an FAA applicant for type certification in September 2025, choosing to utilize Part 23 to leverage the efficiencies introduced by Amendment 23-64. The closure of the G-1 Issue Paper validates this approach as Otto Aerospace progresses towards a groundbreaking aircraft designed for transonic laminar flow—an aviation innovation that stands to redefine efficiency in the industry.
“Today marks a significant milestone not just for the Phantom 3500, but for the entire Otto team,” stated Scott Drennan, President and CEO of Otto Aerospace. He emphasized that the establishment of the certification basis propels the program into an accelerated phase of execution. With a clear alignment on requirements and expectations with the FAA, Otto is now better positioned to demonstrate compliance and advance towards the critical first flight, expected in 2027.
This accomplishment also underscores the FAA's ongoing collaboration with Otto Aerospace in the pursuit of their pioneering transonic laminar flow technology, coupled with the innovative Supernatural Vision cabin—features that have never been certified at this scale before. The company has diligently progressed through rigorous engineering and testing protocols and has recently concluded the Preliminary Design Review, solidifying the technical foundation of the Phantom 3500.
Kerri Hinton, Director of Test Certification at Otto Aerospace, expressed gratitude for the FAA's ongoing partnership in reaching this milestone, reinforcing the company’s unwavering commitment to safety and innovation. She looks forward to advancing the Phantom 3500 through further certification stages.
Currently, Otto Aerospace has initiated advanced material testing for the Phantom 3500 and is making notable progress with its selected suppliers. This diligence is essential for maintaining momentum as the company eyes its target for the first flight and subsequent entry into service in 2030. Flight testing is slated to take place from the company's new base at Cecil Airport in Jacksonville, Florida, which will prepare Otto for the next phases of implementation and manufacturing.
What sets the Phantom 3500 apart is not just its innovative design, but the significant market confidence backing the project. Otto Aerospace has secured a firm order from Flexjet for 300 aircraft—an order valued at over $5 billion, marking one of the largest commitments in the history of business aviation. This outstanding demand illustrates the industry’s belief in Otto's vision and transformation capabilities for private and regional aviation.
Otto Aerospace aims to revolutionize the aviation sector by minimizing energy consumption through their innovative designs. The company’s mission focuses on harnessing laminar flow to achieve a new standard in efficient, affordable, and sustainable aviation. As the Phantom 3500 project moves closer to operational flight, Otto Aerospace continues to live up to its motto: 'This Changes Everything.'
