maybe. if you are at least a private pilot with an instrument rating you can IF the aircraft is equipped and is allow by the manufacture of the aircraft. this is a clip from AOPA.
Can I fly a special light-sport aircraft (S-LSA) in IFR conditions or at night?
Only day/VFR conditions are specifically addressed in the ASTM consensus standards that govern the design, safety, and production of S-LSA. Being that sport pilots and those exercising sport pilot privileges are limited to flying only in day/VFR conditions, this seems appropriate.
On the other hand, if an appropriately rated pilot (example: private pilot with an instrument rating) wants to fly S-LSA under IFR or at night, the aircraft's operating limitations must allow it, and the aircraft must be equipped per
91.205 for VFR flight at night and/or IFR flight. Additionally, 91.327(d) requires all S-LSA to be operated in accordance with the aircraft's operating instructions. Operating instructions differ from operating limitations in that the engine, airframe, and accessory manufacturers issue them; the FAA issues operating limitations.
If you are appropriately rated and would like to operate a special light-sport aircraft at night or under IFR, contact the manufacturer to determine if any provisions can be made.
