Hi All,
Many thanks Ex Brat will have a look at that in depth in due time, I had just a quick scan I saw this below. Would you say this is more less hits the nail on the head why we do not have aircraft in the complex category flying ?

The more complex an aircraft is, the greater the level of organisational and operational support that will be required and, unless the CAA agrees alternative provision through a suitably competent design organisation, the continued involvement of the manufacturer will be required.
