Hi Turbs,
Not sure if we are in disagreement about the need for training to improve safety around maintenance ... my argument is about the need to improve accessibility to training.
Never the less, I still say that very few ac fall out of the sky because of mechanical failures from bad maintenance, it mostly has to do with other factors... therefore I don't think the RAA needs to apply brakes or restriction to hand out an L1 but improve training.
Btw ... not sure I know about the incident at Tyabb you mention, are you sure it was a Subaru and not a Jabiru engined ac? .. I recall Jab powered ac incident like that???
Cheers
Vev
