Initial Notification (#A99O0109): The Bell 206B helicopter pilot/instructor and student pilot were returning to base following a training session of practice autorotative landings in the training area. While en-route, the instructor simulated a failure and the student pilot carried out an autorotative forced approach and landing in a clearing 8NM east of the Buttonville Airport. The helicopter landed heavily with some forward cyclic control input. The instructor checked the helicopter in the hover and elected to continue the flight to base. Company maintenance reported that upon inspection of the helicopter they found wrinkles in the helicopter tail boom and damage to the main rotor head system, consistent with the rotor and transmission rocking forward. The helicopter was removed from service.
