Narrative:
Practicing precision automatic-rotations at clover field airport in gusty wind. The tail rotor of my helicopter contacted the ground as I was leveling the skids. The tailskid had been replaced with a non standard unit made out of aluminum, and bent back tail rotor. Struck ground causing damage to tail rotor gear box. Helicopter automatic-rotated to ground without further incident. Should not have been practicing precision automatic-rotations in gusty winds and should have stopped flare at higher level. Tailskid should have been original equipment.
