    For what it's worth...
    At one time, the FAA classified installing wings on gliders as preventative maintenance. In '87 this was REMOVED from part 43,
    https://static1.squarespace.com/sta...2fe131f8fb14f4b7/1464113792897/05+06+1987.pdf
    Also added words in glider pre-flight (part 61) about training to install wings that have since evaporated and been replaced by just "preflight operations" near as I can tell.
    So, while one can argue that it doen't matter for an Avid (E-AB) for an S-LSA the above reference indicating that installing wings is normal operation per the FAA (at least for gliders) might be a handy reference if you have to deal with a pain in the butt inspector.

    Yea - no argument here. The only issue would be when you run into some paperwork "expert" as the original poster...
    Then it comes down to "is it maintenance" or "normal operation".  Putting a paragraph or two in a manual under a section "preflight checklist" gives you something to point at when someone wants to see paperwork.
    The other argument is that since part 43 does not apply (per 43.1) then it doesn't matter if it's maintenance (as it is on my ride), and the op-lims only require that you log the condition inspection then you just do it and go on your way.

    Maintenance: 43.1 B applicability - part 43 (which requires A&P, allows minor maintenance, etc.) does not apply.
    Condition inspection: What it says in the operating limitations. Probably should have written the repairman cert number.
    Folding wings without log book entry  - don't have a source for that, but obviously common with many models of aircraft. Is it covered in the aircraft "manual"?

  4. Geoffrey Thorpe added a post in a topic Transponders and Airworthiness inspections   

    I bought my ride without a transponder and flew it into an airport under the class B ring of death (ONZ) - phone call to the tower ahead of time (told to stay clear of Bravo), call up on the radio when I got close to the 30 nm ring (They didn't see me on radar at that point). After installing the transponder (and leaving it off), use the same process to get out of the B ring and into a C airport for the initial check. But since then, I have found a couple of "trunkers" who will come out and do the checks. Leave the hangar unlocked, log book and check on the glare shield and magic happens while I am at work :-)
    Dunno what would be required for the first inspection though.

    FWIW, I find a drywall lift to be handy when single handed wing removing / installing on my Merlin GT. I do have to get someone to help get it on/off the lift, but that's just a grab someone for 30 seconds.
    Without the hoist, my daughter can hold the wingtip while I undo things at the root.

    The Stitts manual has directions on testing polyfiber fabric. They say you can use the Maul tester if a problem is suspected, but the real test is to cut a strip, strip the paint, then hang a weight from it. The strength shouldn't be lower than the equivalent cotton. I don't recall if there was a table of the different fabrics and expected strength - and the book is at the airport.

    Your operating limitations will specify that you do the inspection as per appendix D of part 43.

    Your encoder will match the altimeter (which is what you want).

    FWIW - a solution of Drano crystals (Sodium Hydroxide) and water will dissolve aluminum deposited on steel cylinder liners. And, modeling clay (Plasticine) will plug holes and keep the Drano from the aluminum casting.

    Because he has a certificate that was issued after the FAA started marking all new certificates as "English proficient" on February 11, 2008

    Ask your AI if he/she is going to have a shit fit or if it's no big deal in their opinion. If your AI is happy, then everybody will be happy.
