Narrative:
On 15 February 2015, the pilot of a Bell 206 Long Ranger helicopter was conducting sling load operations involving moving fuel drums and an electric generator a distance of 150 metres. During a sling load release under the direction of a ground-based load master, the helicopterís engine failed. The investigation found that a small ball of non-ferrous material used in pressure blasting for cleaning/polishing during engine overhaul had become lodged in the orifice of the Pc diffuser union, effectively blocking the Pc air line.
The investigation was unable to determine when or how the ball had entered the Pc line. It is likely that the non-ferrous ball entered the Pc diffuser union during the last engine overhaul.
The blocked Pc fuel line starved the engine of fuel at a critical time of the flight.
The AIC issued recommendations to the Civil Aviation Safety Authority of PNG, the operator Helifix Ltd, and the engine overhaul company Gas Turbine Overhaul Pty Ltd, to address safety issues noted during the investigation.
