The pilot, accompanied by two ground engineers, took off from Rand Airport on a test flight after maintenance work was performed on the gearbox and fuel control unit of the helicopter. After a satisfactory test flight of approximately 45 minutes, the pilot made a turn to land on the helipad close to the tower when he suddenly experienced a loss of power. The pilot then executed an autorotation and elected to land on the grass at the Eastern side of Runway 17. However upon landing the right hand main skid made contact with a rain water furrow on the side of Runway 17. The helicopter bounced once causing the main rotor blades to strike the tail boom. The main rotor blades, tail rotor, tail boom, tail rotor drive shaft, horizontal and vertical stabilizers were substantially damaged. There were no injuries. The last Mandatory Periodic Inspection was carried out on 22-08-2001 at a total of 7044.40 airframe hours and 7037.9 hours since new. The accident happened at a total of 7081.00 airframe hours. An on-site investigation was carried out and the fuel control to governor tee pneumatic tube '?B' nut assembly Part number 6893073 was found completely loose which will result in a minimum fuel flow and / or in fuel flow shutdown. PROBABLE CAUSE: The most probable cause of the accident is that the fuel control unit to the governor tee pneumatic tube ‘B’ nut was not properly tightened after work was performed on the fuel control unit and vibrated loose during flight.
