The incident involved a certificated flight instructor who was providing instruction to a student on the student's first flight. The instructor reported that he was simultaneously controlling the helicopter's flight controls along with the student. While the helicopter was in a hover, it began to drift sideways toward the right. The right skid subsequently made contact with the turf, and the helicopter then "experienced dynamic rollover," as phrased by the instructor.
The instructor further stated that the helicopter's performance and handling characteristics were normal before the event. He did not provide any additional information regarding the cause of the lateral drift or the dynamic rollover. The instructor's account stands as the only description of the event provided.
No details were given about the specific helicopter model, registration, location, or the number of people on board. The time of day, weather conditions, and any injuries or damage were also not mentioned in the source. The instructor's statements are the sole basis for this report.
