Can see where you are coming from regarding Airbus.
If your expensive product whatever it is breaks you go to the name on the product not their supplier, unless you specificaly asked for a modification & even then I would expect the Name to fight my corner, or to say we do not recommend\fit that because!!.
I appreciate this is a simplistic view but with other threads regarding parts, instrumentation, AOG.there seems to be the feeling we are being taken for a ride
