Investigator assessment
Analysis narrative
The instructor pilot said the student was making the landing and was compensating for a cross wind condition. The student suddenly neutralized the controls after touchdown, and, when the wind began to pick up the right wing, reapplied the right aileron and left rudder correction. According to both of the pilot's statements, the student applied full left rudder and the aircraft ground looped off the left side of the runway, striking some runway light fixtures. The instructor said that she could not overcome the students control inputs to correct the situation before the aircraft ground looped.
