## Probable cause

Insufficient lubrication within the tail rotor gearbox, which resulted in the seizure of the duplex ball bearing and a fixed pitch setting of the tail rotor.  Also causal, was the pilot's loss of control, which was the result of a relative low speed/high power combination during a go-around attempt.  A factor was the manufacturer's lack of procedures for fixed tail rotor pitch settings.
