I recently did a wing pull AD. The owner had the plane all ready when I arrived. Fairings off, interior removed, cotter keys out, etc. 2.5 hours later I had the wings back on and the log filled out. Add maybe 1-1.5 hours if had to pull the fairings and interior stuff. Then add another 1-1.5 hours to torque bolts, cotter keys, fairings, etc. I have pulled a fair number of Ercoupe wings and have my favorite sockets and end wrenches for getting at the bolts. I also have an pretty good idea of what can go wrong. The big bolts can be stuck due to old grease--or no grease and corrosion. There can be misalignment and the bolts might have been driven in sometime in the past. Pitot-static connections might be deteriorated and require renewing. Electrical connections made up with crimp splices rather than the proper connections. Fairing screws can be frozen-holes oversized, etc etc. Actually pulling the wings and replacing them needs two people. That will add another hour or so to the labor bill for the second guy. I feel that the 5 hour labor estimate applies to experienced Ercoupe wing pullers where everything goes pretty well. Double that if the plane and AD is dropped at an FBO that doesn't do Coupes. Add some more time if you bring your plane to and old guy like me who doesn't move too quickly any more. <G> But I work cheap so I guess that evens thing out.
