Eu não sei muito sobre os LSAs, mas os regulamentos dizem que os LSAs com um certificado de aeronavegabilidade especial não podem ser usados em operações comerciais (com duas exceções).
Este documento da FAA diz que um LSA de controle de mudança de peso terá um certificado de navegabilidade especial:
A special airworthiness certificate in the light-sport category is issued to an aircraft that meets the definition of light-sport aircraft (LSA), is manufactured to the applicable consensus standards, and is one of the following five classes of the LSA category: airplanes, gliders, powered parachutes, weight-shift-control aircraft (commonly called trikes), and lighter-than-air aircraft (balloons and airships).
E 14 CFR 91.327 diz:
(a) No person may operate an aircraft that has a special airworthiness certificate in the light-sport category for compensation or hire except—
(1) To tow a glider or an unpowered ultralight vehicle in accordance with §91.309 of this chapter; or
(2) To conduct flight training.
