| Subject: | another fuel tank leak |
Owner complained that the fuel leak was fixed by his mechanic last year but
it still leaks. =C2-
I removed the access covers and peeked inside. =C2-No fewer than 6, and as
many as 8, attempts to reseal the tank. =C2-There is red, orange, black,
brown, gray, and, of course, lo-adhesive sealant all over the place in the t
ank. =C2-Oh, yea, there is also a green coating all over the bottom of the
filler neck that looks like epoxy. =C2-The lo-ad sealant is smeared all o
ver the spar; perhaps the guy thought the spar was leaking. =C2-The guy wh
o put in the red stuff must have believed it was leaking though the skin sin
ce it is spread all over every flat surface except the area where it 'MIGHT'
be leaking. =C2-The green epoxy is all over the area between the two ribs
(on the outside of the tank) where both the tank and the middle wing panel
come together. =C2-There is lo-ad sealant dripping all over both ribs also
. =C2-
I removed the wing and started scraping. =C2-I scraped for 3 hours on it t
oday and managed to clean an area about 9 sq inches. =C2-This one will cos
t somewhere in the $2500 to $3000 range. =C2-
