If you upholster aircraft interiors, you already know the leather has to do two jobs: pass the burn test, and still look right under cabin light years from now. Everything else — brand name, tannery story, minimum order — is negotiable. This guide lays out how the options actually differ, including our own Slipstream line, so you can buy with your eyes open.
The one non-negotiable: FAR 25.853
Any leather going into a certificated aircraft interior has to meet FAR 25.853 vertical-burn requirements — burn length under 6 inches, self-extinguishing within 15 seconds, limited drip. If a supplier can't hand you a burn certificate tied to the dye lot you're buying, the material doesn't belong in the airplane, no matter how nice the hide feels.
That's the first question to ask any leather source: "Can you give me a burn cert for this exact lot?" If the answer is vague, keep walking.
How the market breaks down
The big tannery brands — Moore & Giles, Muirhead, Cortina, and similar houses — make excellent aviation leather and back it with in-house flammability testing. They're the default for OEM programs and large completion centers. The trade-off: they're built to sell in volume. Minimums, lead times, and pricing are set up for shops buying by the pallet for a full-cabin program — not the shop doing a two-seat repair next Tuesday.
Supply-house resellers stock cut pieces and small lots. Handy for a quick patch, but you're often a step removed from the burn documentation, and color consistency lot-to-lot can wander.
Slipstream Aviation Leather sits in the gap: FAR 25.853 fire-certified full-grain, burn certificate per dye lot, sold by the hide, free-shipped, with no minimum order. It's built for the working shop — the one that needs a certified hide for one job this week and three hides for a cabin next month, without committing to a program.

How much leather do you need?
A standard hide runs roughly 50–55 square feet — call it 2.5 to 3 yards of usable material. A pair of executive seats is often one to two hides depending on wastage and pattern. If you're close to a hide boundary, order the extra hide up front — dye-lot matching after the fact is the expensive way to learn this lesson. We wrote a full hide-to-yardage guide if you want the math.
The honest bottom line
If you're running an OEM program, the big houses are a fine home. If you're a shop that wants certified aviation leather without the minimums, with a burn cert you can actually put in the logbook, shipped free — that's exactly what Slipstream is for. Order a hide, or ask us to mail a sample deck first so you can check the hand yourself.
