## Probable cause

An in-flight loss of control caused by the main rotor severing the tail rotor drive shaft as a result of the pilot's cyclic pull-up into a tailwind for his second approach and landing. The loss of the tail rotor caused an uncontrollable descent and tree strike with the main rotor and in-flight collision with terrain. Contributing to the accident was the pilot's improper decision to make a downwind approach and landing.
