The pilot was carrying out circuit practice in his aircraft. After about 15 minutes flying the engine stopped. Realising that the aircraft would not glide to the strip, the pilot attempted a forced landing in a grassed paddock just short of the property boundary fence. Just after touching down, the aircraft struck the trunk of a fallen tree and the landing gear was bent rearwards. An inspection of the wreckage found that a hose clamp holding the fuel line to the inlet side of the carburettor had failed and allowed fuel to siphon overboard. The failure of the clamp had resulted from the incorrect size clamp being used and the resultant size differential resulted in geometrical discontinuity and circumferential stress overload. The engine failed due to fuel exhaustion.
