A tail rotor failure at night in Saudi Arabia
We started a slight descent to 2500 ft. AGL, completed the pre-landing checklist, and turned to a 5-mile final to the LZ. As I added pedal to adjust for the change in our power setting, I realized very quickly that we had no tail rotor authority. I quickly checked to verify the condition, found that I had a full range of left and right pedal, but with no result.
