Otto Aerospace (Fort Worth, Texas, U.S.) has announced G-1 issue paper finalization, which establishes the company’s flagship Phantom 3500 aircraft’s type certification (TC) basis with the Federal Aviation Administration (FAA) under 14 CFR Part 23.

Otto became an FAA applicant for TC in September 2025, strategically electing to use Part 23 to take advantage of the certification efficiencies introduced under Amendment 23-64. Closure of the G-1 reflects that strategy now in execution.

In parallel, Otto is actively engaged with the FAA East Certification Branch to close the G-2 issue paper defining the means of compliance for the Phantom 3500 certification program.

“Now that the certification basis is in place, the program moves into a higher gear on execution,” notes Scott Drennan, president and CEO of Otto Aerospace. “We have alignment with the FAA on what we need to demonstrate, and that gives us real momentum as we move toward first flight and entry into service.”

The milestone also reflects continued FAA engagement with Otto’s transonic laminar flow technology and its Supernatural Vision cabin —innovations that the company claims no manufacturer has previously advanced into certification at Otto’s scale. Otto has moved the program forward through extensive testing and engineering and recently completed preliminary design review.

Otto has already begun advanced material testing for the Phantom 3500 and continues to make strong progress with its top-tier suppliers, reinforcing the program’s momentum toward first flight in 2027 and entry into service in 2030. Flight testing will be conducted from Otto’s new home at Cecil Airport in Jacksonville, Florida.
