I began the flight with my student around AB40. I was in the left seat and her the right. The AWOS stated wind 020 degrees at 11 KTS when we departed. We left the north ramp and taxied to and crossed runway 9 at the numbers. We practiced hovering in the field northwest of the pyramid building. We then departed for right closed traffic for parallel runway 9 and returned to that area. Upon coming back into a hover, I noticed the wind had shifted more to favor runway 36. We hovered east to runway 36, departed, and did 1 traffic pattern with right traffic for runway 36. We came to a hover south of the paved runways 9/27 and again started to practice hovering. At several points while practicing, the aircraft became unstable, I corrected. We did all hovering from a ht between 5-10 ft AGL. The last time, when hovering, the aircraft began to drift left and turn left, with a nose low altitude. I came into correct and I raised the collective. The aircraft continued to settle onto the ground and rolled to its left side. I shut off the gas, as it was leaking, turned off the key, shut off the switches, helped her to exit, and walked back. There were no injuries.

Title: A CFI AND STUDENT IN AN R22 HELI EXPERIENCE A LOSS OF ACFT CTL WITH THE ACFT SETTLING ON ITS L SIDE DURING A HOVER OP AT LANSING MUNICIPAL, IGQ, IL.
Narrative: I BEGAN THE FLT WITH MY STUDENT AROUND AB40. I WAS IN THE L SEAT AND HER THE R. THE AWOS STATED WIND 020 DEGS AT 11 KTS WHEN WE DEPARTED. WE LEFT THE N RAMP AND TAXIED TO AND CROSSED RWY 9 AT THE NUMBERS. WE PRACTICED HOVERING IN THE FIELD NW OF THE PYRAMID BUILDING. WE THEN DEPARTED FOR R CLOSED TFC FOR PARALLEL RWY 9 AND RETURNED TO THAT AREA. UPON COMING BACK INTO A HOVER, I NOTICED THE WIND HAD SHIFTED MORE TO FAVOR RWY 36. WE HOVERED E TO RWY 36, DEPARTED, AND DID 1 TFC PATTERN WITH R TFC FOR RWY 36. WE CAME TO A HOVER S OF THE PAVED RWYS 9/27 AND AGAIN STARTED TO PRACTICE HOVERING. AT SEVERAL POINTS WHILE PRACTICING, THE ACFT BECAME UNSTABLE, I CORRECTED. WE DID ALL HOVERING FROM A HT BTWN 5-10 FT AGL. THE LAST TIME, WHEN HOVERING, THE ACFT BEGAN TO DRIFT L AND TURN L, WITH A NOSE LOW ALT. I CAME INTO CORRECT AND I RAISED THE COLLECTIVE. THE ACFT CONTINUED TO SETTLE ONTO THE GND AND ROLLED TO ITS L SIDE. I SHUT OFF THE GAS, AS IT WAS LEAKING, TURNED OFF THE KEY, SHUT OFF THE SWITCHES, HELPED HER TO EXIT, AND WALKED BACK. THERE WERE NO INJURIES.
