When I tested my wings I had the same thing happen.
When you fill the balloons when it is warm they will go down when the
temperature goes down overnight due to air having more volume when it is warm
than when it is cool.If you let them warm up again the next day the
balloons will partially re-inflate.My balloons would not
completely re-inflate but someone at lancair said if they will stay
inflated 8 hours they are OK. So far I have no
leaks.

Subject: [LML] Re: wing leak
Does anyone have good ideas for finding the leak
location? I'm still building.
I tested my Legacy wings by
plugging all but two holes and covered the vent and fuel cap (latched) with
packing tape. I then installed barbed fittings to the two remaining
threaded holes and put a party balloon over one and a tube on the other.
I then compressed the tank and balloon through the tube until the balloon was
filled and capped the tube. I checked all the plumbing and capped holes
with soap bubbles, but saw no signs of leaks. However, the balloon was
partially deflated the following day. A tied-off test balloon didn't
deflate measurably, so I must presume that the air didn't bleed through the
balloon.
Does anyone have any ideas for further leak tests? I've
heard of putting some freon into the tank and using a sniffer to find leaks,
but doing this without false alarms within a garage seems tough.
Besides, I don't have the freon or the tester. Has anyone tried this and
if so, any suggestions? How about other methods?
Thanks in
advance for your help.
