NTSB investigations: Flight Design CTLS
4 cases on aircraft the registry lists as Flight Design CTLS, where the sequence of events included Aerodynamic stall/spin. Aircraft are matched to the registry by N-number and event date, checked against the reported serial number, make and model, so older matches can be wrong.
