Spar Nails Again

[powers]

There are a lot of discussions about nails in the archives, but none that answer my question specifically, I think. I ordered brass plated cement coated AN301-20-5. They are 5/8 in. Can I use these to attach the ribs to the spars?

....I sure hope so, that's exactly what I ordered (and using) from Aircraft Spruce. take care, Jim

Wag Aero says the following: "THE DRAWING FOR THE 7AC WING FRAME ASSY, 7-439, SHOWS 80 AC-301-16-5 NAILS PER WING, LEFT AND RIGHT". I am holding out until Wag Aero gets the 16s in stock. If they still have problems in finding a supplier by the time I need to finish the wings, I will consider using the smaller 20s.

Ok, I thought the 20s were larger. Being that the 20 means 20 gauge. If you look in the Aircraft Spruce manual they specify AN-301-20-5 as: an-301=formerly FF-n-105, -20 as 20 gauge, and -5 as 5/8. However, I did notice that the old holes in my ribs are bigger that the an-301-20-5s.

Aeronca drawing #7-439 (at 3rd rib from butt, rear spar) shows
AC-301-18-5, 20 GA., 5/8 long cement coated...?? not sure I understand "18" -vs- "20 ga"
but I have found several mistakes/discrepensies on drawings. It says "20", I went with "20". anyway, after 60 years,
I wonder how many wings are out there with Home Depot brads? Jim

Or Screws

Screws?

Or Screws

If the plane is experimental, almost anything is allowed. Otherwise its what is called out in the blueprint, or new spars when the holes are too large.

I ran across a Champ wing that was using gimp pins to secure the ribs. I don,t know long they had been in there. All of the pins were as tight as a ducks butt in salt water.

Just a suggestion, nothing to do with nails, and yet Everything to do with nails.

Pick up a copy of AC 43-13. "acceptable techniques,practices,and procedures,..."

It is a many paged book chock full of tidbits of info relative to the inspection, repair, and restoration, of aircraft.

It can be had at Aircraft Spruce, and similar dealers of aviation supplies.
Also from FAA.gov. But it's cheaper through an independent source.

You can also download it free off of the internet, then print it out if needed, or if not just view it on the computer and print off the pages you need.
