Rather than discarding your bags just because they are over 10 years
old, remove them and inspect them. Unless they are obviously rotten
lay them out on the ground and fill them.

Tell us what they are made of and whether they leaked, then we may
tell you to fly with them, or chuck them.

Smiley bags are good for 20 years or more. I flew my ASW-19 for 15
years (1,500 hours) with no bag problems except one minor wear spot
that needed patching. I was the third owner and I'm pretty sure the
bags were fitted shortly after it was new. I did replace the bag root
fittings and fit piccolo pipes after the first season.

BTW before you pull the bags be sure you understand how they are
retained and, if there is a pull or retaining string, don't lose the
end in the wing!
