How do you
get a Cherokee tank out? Derivet? Remove a wing?



Cherokee tanks don't have bladders. The tank forms a portion of the
leading edge of the wing. It is held in by about 70 screws around the
edge of the tank. After taking out the screws the tank slides forward,
often with the help of a 2x4 place along the rear edge on top of the
spar and a rubber mallet. Assuming the screws haven't corroded into
place, it takes about a half hour to pull an empty tank off a Cherokee.

The tanks do start to leak at the seams sometimes. They can be resealed
by drilling out all the rivets, cleaning up the pieces and putting them
back together with new sealing compound at the seams, which is typically
done by a shop that specializes in rebuilding cherokee tanks.
