According to the instructor, after demonstrating some ground maneuvers, he entered the pattern to demonstrate a practice autorotation. The instructor stated that they entered the autorotation at approximately 850 feet above the ground. The airspeed, and rpm were in the green, and the descent was around 1500 feet per minute. The instructor stated that at approximately 40 feet above the ground, they started the flare. At the end of the flare, he announced "recover," and then announced, "I have the controls." The instructor was unable to recover the engine rpm. The instructor leveled the helicopter and landed hard on the runway. The impact with the runway crushed the landing gear skids upward, and buckled the fuselage and tail boom.
Probable Cause: the instructor's failure to maintain adequate rotor speed during the landing flare, resulting in a hard landing. Contributing factors include the student's delay in relinquishing the controls and the instructor's improper supervision.
