ShyTorque,
It isn't a case of pilots not being capable of carrying out limited tasks and certifying them. Provided they have received specific training, Pilots ARE quite capable and both the previous and the present rules allowed it. As an avionics LAE I was also trained to do transit inspections and perform and certify specific airframe tasks, such as wheel and brake unit changes for example. I haven't converted to a JAR 66 licence and probably never will, but if I did I would be required to meet the experience requirements and pass the JAR66 examinations for an A rated licence as well as receive task specific training before I would be allowed to continue to do that for which I was previously qualified. It is that situation concerning limited authorizations, and which makes no sense, that Bus429 is trying to highlight.
