Joby's Air Taxi Just Passed Its Toughest Test

Joby Aviation clears Stage 4 of FAA type certification, putting the first US commercial eVTOL license within reach

7 May 2026

Joby Aviation has cleared the fourth of five stages in the US Federal Aviation Administration's type certification process, placing the California-based company closer to commercial operation than any electric vertical take-off and landing manufacturer has previously reached with American regulators.

Stage 4 marks the point where regulatory scrutiny shifts from design documentation to physical hardware. Every aircraft produced at Joby's Marina facility was validated against approved design specifications, with propulsion systems and fly-by-wire flight controls both assessed directly by the FAA. Completion confirms the aircraft as built matches what was submitted for approval.

Three steps remain before paying passengers board. FAA test pilots have begun flight evaluations of the S4 aircraft. A type certificate, anticipated in late 2026, would confirm airworthiness across all performance conditions. A separate air carrier certificate must then follow before commercial routes can open. Joby is developing vertiport infrastructure jointly with Delta Air Lines at New York's JFK and Los Angeles International Airport.

Joby has targeted late 2026 for initial service in both cities, with fares projected between $150 and $300 per trip. Independent analysts place realistic entry closer to mid-to-late 2027.

The milestone carries weight beyond Joby. Richard Aboulafia of AeroDynamic Advisory noted that Stage 4 completion demonstrates the FAA's powered-lift certification framework is operational, giving subsequent manufacturers a proven regulatory pathway to follow. Joby began the process in 2018.

Legislative activity is adding further structure. Introduced in February 2026, the bipartisan Aviation Innovation and Global Competitiveness Act calls on the FAA to publish standardised certification timelines, a reform that could reduce uncertainty for the broader advanced air mobility sector.

The question for US commercial electric aviation is no longer regulatory viability, but timing.
