How much training is needed to learn you don't use a jet engine intake as a desk??
Well, if you offer a low hourly rate and employ people who may or may not have experience in the aviation environment then you need to provide more training ( initial and ongoing) than if you pay more and get aviation folk who stick around the industry for decades and mentor their co-workers without even knowing it.
There is no free lunch.
My disappointment lay in the fact that the ATSB doesn’t have the courage to identify the real cause and is satisfied with supporting the way things are currently done even when safety is impacted. Or are the ATSB so inept now days that they believe what they wrote?
