## Analysis

The helicopter was being operated as a corporate/executive flight when it received substantial damage during a hard landing. The pilot had been demonstrating inputs needed to control the helicopter to the passenger. He was demonstrating a normal approach to a hover by talking through all the control inputs during a visual approach. The tail boom separated from the fuselage during the hard landing.
