Joby Aviation has achieved a pivotal milestone by initiating power-on testing on its first FAA-conforming aircraft, marking a critical step toward Type Inspection Authorization (TIA). This event signifies the start of extensive hardware and software integration tests, paving the way for subsequent “for credit” flight testing with Federal Aviation Administration (FAA) test pilots. This phase is a fundamental component of the final stage in the rigorous FAA Type Certification process, bringing the company closer to its goal of launching commercial passenger service with its electric air taxis.
According to Didier Papadopoulos, President of Aircraft OEM at Joby, this subsystem testing represents the culmination of over a decade of engineering and certification refinements. He emphasized that this moment is where the company’s type design, manufacturing process, and certification strategy converge into a single physical asset, validating their ability to design a safe aircraft and produce it reliably. This achievement is described as one of the most significant milestones in Joby’s history, solidifying the path toward FAA certification.
The aircraft undergoing testing is the first of several TIA-conforming aircraft to be manufactured. It was built under Joby’s established quality management system, precisely adhering to the approved type design. All components are FAA-conforming, having been constructed to designs approved by FAA Designated Engineering Representatives and inspected by FAA Designated Airworthiness Representatives, in line with the company’s FAA-approved test plans.
With power-on testing complete, the aircraft will now enter a comprehensive preparation phase. Flight testing by Joby’s own pilots is anticipated to commence later this year, serving as a precursor to FAA pilots taking the controls for the official TIA testing in 2026. This critical TIA phase will involve close collaboration between Joby and the FAA to ensure the aircraft meets all stringent safety and performance requirements.
The TIA testing regimen is comprehensive and multifaceted. It includes Performance Validation, where FAA and Joby test pilots will assess the aircraft’s range, speed, and energy management under real-world conditions. Another key area is Control and Handling, which involves evaluating the flight controls and handling qualities across all flight regimes, from vertical takeoff and landing to wingborne cruise. Furthermore, the TIA phase will validate the future operational procedures for commercial service. This involves inspecting maintenance manuals, finalizing the pilot training curriculum, and verifying the functionality and reliability of all onboard systems, including avionics, propulsion, and critical redundancies.
The data gathered throughout the TIA process will be instrumental. It will form the basis for the FAA’s final determination on issuing a Type Certification for Joby’s aircraft. This certification is the essential approval required to begin commercial operations, representing the final gate before Joby’s electric air taxis can enter service.
