The helicopter was engaged in a sling operation to lift a powerline to the top of a transmission tower. The pilot was hovering the helicopter about 60 ft above the 30-ft tower, and had just passed the powerline to the linesman when the engine began to "spool down", resulting in a total loss of power. The pilot immediately banked the helicopter to the right to avoid personnel on and below the tower, and attempted a landing in light scrub. However, the helicopter came to rest on its right side, incurring substantial damage, and slightly injuring the pilot. The maintenance investigation found that the engine fuel system was contaminated with water, discoloured fuel, and particle debris. After the engine fuel system was cleaned, the engine was successfully ground-run. The helicopter had spent 45 hours on firefighting duties in the 60 hours since the last maintenance inspection. During the firefighting operations, refuelling was routinely undertaken from an assortment of drum and mobile bowser fuel sources. "Hot" refuelling also accounted for a significant proportion of these refuelling operations. It is probable that the fuel system was contaminated during those refuelling operations.
