I am pretty sure that the crashworty fuel system modifications were incorporated in the late 80s, having been a JT on the MU team that did the modifications. The systems have never been fitted for 30 years..
The system itself was very simple as been stated, but there is no satisfactory way of testing such systems without ripping all the components out. I cannot see why the cornoner can make the statement that he has on maintenance errors like he has. He says that a valve might not have worked. I think it was more likely that the tanks or anti spill lines were damaged being the source of the fuel IMHO.
TD, this accident bears little relation to XV230, so please don't speculate that it does.
