Investigating agency: CAA SouthAfrica
Narrative:
The helicopter went down in mountainous terrain while water bombing the area. The pilot sustained fatal injuries.

Probable cause: The pilot was unable to regain control of the helicopter following a loss of tail rotor thrust, which was caused by fracture of the left-hand aft control cable during flight, followed by the failure of the tail rotor driveshaft.

Contributory factors: The left-hand aft control cable fractured due to mechanical wear at the pulley location, which caused secondary damage and failure of the tail rotor drive train.
Failure of the maintenance organisation and maintenance personnel to follow required maintenance procedures, thereby not detecting the deteriorating condition of the aft control cable timeously (absence of daily inspections).
The maintenance engineering staff complement employed by the AMO at the time was found to be inadequate to conduct proper maintenance inspections of the ageing fleet of helicopters as called for in the aircraft maintenance schedule.
