Aviation Forum / General / Homebuilt / February 2005Removing cherokee wings..
Hi, Has anyone had experience with removing the wings on a Cherokee 140? Need to move it to rebuild. How hard is it to re-install them. I heard something about tapered pins or bolts.. Pete I read about one guy who flew through two trees. They came off easily. Putting them back on was much tougher. > I read about one guy who flew through two trees.

The major draw back to that method is the fuselage tends to get a bit dented on impact. Dan, U.S. Air Force, retired > I read about one guy who flew through two trees.

Maybe your method would be best. Kinda hard on the trees, though. Dan, U.S. Air Force, retired Sounds like it's time for "Mr. Chainsaw" I tried e-mailing you the appropriate pages from the service manual, but it bounced. Pick up a service manual for the Cherokee 140. Pages 4-4 to 4-14. > Hi, > Has anyone had experience with removing the wings on a Cherokee 140? > Need to move it to rebuild.

I heard >>something about tapered pins or bolts.. Pete I took my wings of my 1974 140 to do a spar inspection a few years back. Not too difficult to do but it does require some extra hands. I built a fuselage cradle out of 2x4's, jacked the wings, and slipped the cradle under the cabin. I had access to a heavy tail stand. Undid everything (fuel lines, wires, etc.), undid the spar bolts and slipped the wings out and laid them on the grass. The airplane sat outside for a couple of weeks while I did some cleaning up and painting. I recall that I took the tanks out of the wings beforehand. Reinstall was a reverse of the removal--extra hands very important to assist in lining up the holes. As I recall, I used new spar bolts and nuts (the bolts are specials with close sizing). My AME (A&P) supervised everything, installed the bolts, and set the torques. > I HAVE the service manual. My Question was has anyone here actually done > it??

So I guess you didn't have any major proplems re-installing them. How about the gasket around the wing root? I have heard its a bear to install...

Pete I think I cleaned the gaskets up and installed them to the wings and secured them with something....maybe crazy glue?? So long ago, I can't remember.. > Thanks for the info.
