NTSB accident and incident record under N543SX

ERA18LA083Accident on February 5, 2018 at Carrabelle, FL: fatal, substantial damage (1 fatal).

Aircraft on the NTSB record: Gregory Newman SONEX TRAINER · serial 0543

A loss of engine power for reasons that could not be determined because the airplane was not recovered. Also causal was the pilot's decision to conduct a low-altitude turn following the loss of engine power, which resulted in an exceedance of the airplane's critical angle of attack and an aerodynamic stall.
