It took about 10 minutes to get the wings in place and the temporary pins installed. There were 3 of us doing the work. I haven't installed the hardware since I'll be taking the wings off to do some more work before I go to the airport. I'm working on getting the controls adjusted and centered. I can see where getting upside down in the cockpit to attach the flap tubes is going to be a pain. At least I enlarged the wing rib holes so there is lots of room to get a hand in there.

Having temporary (tapered) pins go in first is much preferable to trying to get the actual hardware (flat-ended bolts) in place. With 4 tapered pins in place you can just pop out one at a time as you put in the actual AN bolts.

Hello,

I am new to Sonex, and have searched the forums, I have found no answer to my question. I did find the documentation provided by Sonex on removal of and wing installation.

On a finished and flying aircraft, can anyone reinstall the wings legally or do you need to be the builder or A&P, is an airframe logbook entry required?

Thank you

Hi Jim

Anyone can uninstall and reinstall the wings. I found the process to be more time consuming than 15 minutes. It took a couple of hours to get them off due to the location of the flap bolts and nuts, and an hour or so to reinstall them.

My opinion is no logbook entry is required.

The only thing a second or third, non builder owner cannot do is the condition inspection. An A&P is required to do that.

Hope this helps.

I would argue that a logbook entry is required, just as if you performed an oil change or valve adjustment. But no A&P required as Robbie said.

Is installing the wings "maintenance"? If you remove the cowl and then reinstall it does it require a log entry? What about inspection panels?

Good question actually. I'm honestly not sure.

Us sailplane pilots rig and de-rig our aircraft (including pulling the wings and tail) just about every day we fly. Many sailplanes are type certified. None that I know of require a logbook entry to rig & fly. A safety inspection after rigging (with a second pair of eyes and hands) is strongly recommended, of course.

I'm not aware that the glider guys make a log entry every time they remove wigs for transport and then rig the glider to fly. However the FAA Glider Flying Handbook suggests there are some best practices relating to checklists tool counts etc:
