It's what happens when someone totally tops off the tank (and filler tube) on a cold winter day. Then pulls the airplane into a warm shop where it sits unattended for a long holiday weekend. Cold auto fuel (with ethanol) expands in warmth of shop and dribbles out cap vent keeping the paint wetted non stop for three days.
A very difficult test for any paint...It has since been repaired and has not reoccured.
Scott,
Have they been regularly using ethanol-laced autogas in the red plane or a combo with 100LL? Any noticeable effect on the Rotax?
A word of caution: If you use fuel filter elements with plastic housings, (common with the 912 series), swap them out for metal housings. We have seen several CTs with plastic bodied fuel filters that have either been deformed or failed when using E10 gasoline.Rotax has approved the 912 for E10, so it should be alright...
Is the fuel cap supposed to show the fuel type and quantity?
