My understanding is that the insurance company determines if repair is justified and when the aircraft is totaled, then they sell it to a salvage operator and pocket the money gained. In the US, there are various colored tags to document the repair/overhaul status of used equipment and licensed mechanics will not install equipment without such a tag or doing the overhaul for you. Anything similar in Europe?
Of course we have that here; being Europe it is even more gold plated, and equally worthless if there is an intermittent defect caused by mechanical damage
I cannot believe that avionics from a "chuted" Cirrus are being salvaged.
