Carbon Cub Kit - Wing Static Test (Ultimate)

http://www.cubcrafters.com - The test you see here is what the aircraft structure would withstand when the airplane's speed is increased to redline, pulled up quickly to a 6G pull-up, and the aileron is fully deflected... all at the same time. The rear spar is typically the weak link in this test, as there is tremendous load applied to the outboard rear spar when the aileron is deflected. Yakima, WA - 7.21.2008

whats the margin of safty is it FFA decided or factory decided

[CubCrafters]

@datzfast These are the same static load testing methods that were used in the FAA Certification of our TOP CUB. The TOP CUB is certified in the Standard Category - FAR 23, Amendment 55. - The only difference is this wing is being tested to 1,865 lb. gross weight whereas the TOP CUB was tested to 2,300 lbs.

What aircraft is this?

[CubCrafters]

@9VARZ It is the wing used in the Carbon Cub EX and the Carbon Cub SS.

@CubCrafters Nice. I wonder how different is it using a simulated rig like this as compared to a static (full) airframe for testing purposes. I'm sure a lot of us here would have seen the footage from the B772 certification trials.

Would simple static load tests like these contribute to FAA certification requirements?

[CubCrafters]

@9VARZ Yes. These are the same static load testing methods that were used in the FAA Certification of our TOP CUB. The TOP CUB is certified in the Standard Category - FAR 23, Amendment 55.

if you think there's someone out there making loads of money on airplanes, you're smoking crack. These guys put out a quality product, and make enough profit to be a reasonable venture, unlike some of the other jokers selling "kits" - basically a box of parts and a pat on the butt for support.

Muito bom, estou diminuindo bem lentamente a minha ignorância sobre o tema.

Obrigado a todos

I did not like the fact that they were rushing the test... 1/2 inch clearance and 1,2,3 put the jacks/stands back on in a rush... too pricey as well. Sorry guys but show more confidence in your product which I am sure is a good one.

After you do a test like that, can that same wing be used on a aircraft, or is it pushed to the limit and be considered over stressed? because I have a design for a wing that I would like to build for myself, I love fiberglass and foam!

they will test a few to destruction but they test all to a set load to make sure that it is airworthy
