Probable cause

The pilot's poor inflight decision in selecting an unsuitable area for practice landings and the pilot's inadequate visual lookout resulting in a tail rotor strike and loss of antitorque control.

Analysis

The pilot made a practice landing to an abandoned concrete building foundation. While at a hover after completing the landing, the pilot executed a 90 degree right pedal turn and the tail rotor struck a structural reinforcing bar that was protruding 18 inches out of the edge of the foundation. Antitorque control was lost and the acft spun 90 degrees before making a hard landing.
