Ply wood was used in the manufacture of aircraft…! For lightness stability and strength.

It’s really thin, and really expensive (like Paris Hilton!).

“Aircraft” rated ply also has to have a higher burn temp than normal ply, so, depending on the location and use, has to be fire-rated for that application. Many plywoods would probably work in a lot of areas, but it has to have certification, which means lab test, etc, which cost more. In some instances it means different wood and glue.

Just like linoleum. When I worked on cargo aircraft, we had floors that were plywood and linoleum covered. The linoleum we used was stamped the same as what you could buy at flooring store but cost 3 times as much. The difference was that the company spent the $$ to have it fire rated, and when sold to an aircraft application, included the testing certification. Bottom line, they paid to get into the market, and charged the market for it.

The regulations make the item safer, but you pay for that safety certification, even if its a common off-the-shelf item. Without the cert, you can’t use it.

Heck in Canada Mosquito Bombers were built almost entirely of plywood during WW11. My dad was a carpenter & he worked for an outfit called “Aircraft Repair” & yup that’s what he did….he repaired them.

Aircraft graded plywood has to meet strict guidelines for strength, weight, rigidity, resistance to temperature extremes, lack if voids, moisture resistance, etc. It’s a higher grade than what you get at the big box stores for general use. While expensive, would YOU trust YOUR life to something less if building an aircraft YOU would be flying in?
