It seems that some people assume that if the engine of any aircraft stops then there will be an accident... this does not have to be the case.Lets face it if the engine stops , the wings don't fall off until you hit something on the ground! After I learnt to fly GA (when we did EFATOs and in flight failures) , I learnt on AUF/RAaus aricraft (Drifter and Thruster) I/we were all taught to fly as if the engine will stop not IF it will stop. If you always fly as if the engine will stop(usually on take off) - and you won't be surprised! (GA or RA Aus)
It seems also that from the article in The Aviation Consumer that most accidents were a result of Pilot error. It could be said that if you have an accident due engine stoppage through what ever reason then that could also be Pilot error.
It also follows that the larger the fleet of aircraft e.g Cessna 150 or Jabiru then the greater numbers will statistically have more recorded incidents..
If people are so worried about engines then perhaps they should do some gliding and learn to fly an aircraft that doesn't have an engine at all. Believe me it will improve your skills no end>>Lets not turn this whole RA AUs grounding/ATSB thing in to another excuse to have an engine bashing forum..
In the Aviation world globally, Pilot error and maintenance errors are the primary causes for accidents and incidents...
