Yep Whyalla Airlines had a Piper Chieftain lose power on one engine, the pilot tried to continue the flight from Adelaide to Whyalla on the engine still running but it failed due to the extra load and the plane ended up in Spencer Gulf. All eight people on board died including two of my old school friends. The sad part was when the first engine quit the aircraft was over York Peninsular and could have been landed safely, but due to various pressures the pilot felt compelled to continue on to Whyalla.
