Are 2-seat ultralights legal?
You will need a regular FAA airman certificate (Recreational or Private Pilot) and the plane must be registered with FAA and have a federal airworthiness certificate (such as amateur-built experimental). The pilot will then be operating under general aviation rules (FAR Parts 61 and 91). Dual training under Part 103 in a 2-seat ultralight is available through an FAA exemption. Part 103 rules specifically say that an “ultralight vehicle is a vehicle that is used or intended to be used for manned operation in the air by a single occupant.” Two-seat ultralight trainers can only be flown by an instructor operating under an FAA exemption. The only exceptions are ultralight students signed off to solo in the two-seater in which they have taken training from an instructor who holds an FAA exemption .
