The pilot landed and after egressing the helicopter, discovered that a piece of tail rotor skin was lodged in the skirting; the tailrotor had impacted the safety skirting. The helicopter's tailboom sustained substantial damage. The pilot reported that there were no preimpact mechanical malfunctions with the helicopter.
