If the fuel system (to include the fuel tanks) are not built to withstand the Ethanol, it will slowly dissolve the fuel system causing a major failure. Our KIS4's use the "wet wing" method of fuel tanks so if Auto gas with Ethanol has been used there may be an issue hence the borescope inspection suggestion. FWIW: Mark K. was one of the original engineers that worked on the KIS design and is an encyclopedia of knowledge about the KIS line of airplanes.

Keep in mind that one side of the fuel tank is the main wing spar and it is built w ith epoxy resin. There was at least one KIS TR-1 that had the main spar hig hly compromised by auto fuel use.
