Part 135 FAA Certification Achieved By Joby Aviation In a hugely important step towards entering into service (EIS), Joby Aviation has received Part 135 certification from the Federal Aviation Administration (FAA). This is a key piece of certification that will allow the company to commence on-demand air-taxi services in the future. The timeline shortened significantly as this approval was expected to come in the second half of 2022. However, it isn't the only part of approvals needed for EIS. Joby Aviation also needs to achieve Type Certification (TC) of the aircraft as also attain a Production Certificate (PC) which would allow them to produce the aircraft on commercial scale for customers.
