Joby Aviation, Inc., a pioneering company in the realm of electric air taxis for commercial passenger service, has now attained a further regulatory approval.

The Federal Aviation Administration (FAA) has greenlit Joby’s certification plan for its propulsion system. All structural, mechanical, and electrical system certification plans have now been accepted by FAA

This marks a further critical step towards the goal of obtaining type certification for Joby’s innovative eVTOL aircraft.

Joby’s Propulsion System

The propulsion system, designed by Joby, is central to the sector-leading performance of the Joby aircraft.

The accepted certification plan includes Joby’s electric propulsion unit, propeller system, variable pitch actuation, coolant pump, nacelles, and associated electrical wiring, clearly defining the route to certifying these systems for use in commercial passenger operations.

The FAA’s acceptance of Joby’s certification plan delineates a clear path towards approval of these crucial components for deployment on commercial passenger operations.

Certification Program

Didier Papadopoulos, the president of aircraft OEM at Joby, expressed his gratitude for the collaborative effort that led to this milestone.

With an approved certification plan in place, spanning structural, mechanical, and electrical systems, Joby’s team is now poised to navigate through rigorous testing and analysis procedures.

This milestone further acknowledges Joby’s commitment to pioneering safety and innovation in the aviation sector.

The FAA type certification process stands as a rigorous evaluation encompassing the design, manufacturing, and performance aspects of novel aircraft types.

Joby’s progress through this process signifies its dedication to ensuring compliance with stringent safety regulations.

With most certification plans accepted and the final document undergoing FAA review, Joby is advancing steadily through the certification phases, focusing now on detailed testing and analysis.

Building on Past Success: Joby’s Testing Initiatives

In 2023, Joby conducted 30 for-credit tests with the FAA, covering diverse aspects ranging from flight electronics units to structural materials.

These tests not only validate Joby’s methodologies but also lay a robust foundation for future FAA for-credit testing endeavors.

Towards Commercialization

In addition to propulsion system clearance, Joby has also recently obtained its Part 145 Maintenance Certificate from the FAA.

This certification authorizes Joby to undertake select maintenance activities on its eVTOL aircraft, marking another crucial step towards the commercialization of its electric air taxi service.

Designed to accommodate a pilot and four passengers at speeds of up to 200 mph, Joby’s electric air taxi heralds a new era in urban air mobility.
