Key Takeaways:

Joby Aviation has begun manufacturing FAA-conforming propeller blades at its Dayton, Ohio facility, a critical step towards certifying its eVTOL air taxi.
The Dayton plant is designed to produce up to 15,000 blades annually for 500 aircraft, with the propellers being central to the air taxi's low acoustic profile and complex engineering.
This manufacturing milestone, alongside recent expansions and partnerships with companies like Delta, Uber, and Toyota, reflects Joby's accelerating progress toward commercial readiness and FAA type certification.

Electric vertical takeoff and landing (eVTOL) air taxi developer Joby Aviation has begun building propeller blades that it claims will meet requirements for FAA certification.

The company on Friday said it aims to churn out as many as 15,000 blades per year from its 140-acre site at Dayton International Airport (KDAY) in Ohio, acquired in 2023 to serve as its core manufacturing plant. Conforming blades are expected to be completed next month and installed on aircraft for flight testing in 2026.
