CubCrafters Carbon Cub EX-3 Kit Completes Evaluation by FAA National Kit Evaluation Team

In April of this year CubCrafters received notification from the Federal Aviation Administration that their National Kit Evaluation Team had completed its evaluation of CubCrafters’ Carbon Cub EX-3 amateur-built aircraft kit.

Completion of their evaluation means the FAA has reviewed and approved the Carbon Cub EX-3 and that the aircraft has been added to the list of Amateur-Built Aircraft Kits that satisfy the majority build requirement (commonly referred to as the 51% rule) on the FAA website. The EX-3 joins the original Carbon Cub EX kits on the list, which the FAA provides as a service to prospective aircraft builders researching kit options.

“This is really good news,” says Mitch Travis, CubCrafters’ Kit Program Manager. “It affirms that the majority of the Carbon Cub EX-3 kit construction is undertaken by the builder – a key part of the definition of an amateur-built aircraft.” He continues, “Our customers can have confidence that even though the EX-3 is one of the most complete kits and quickest assemblies of any two place tandem STOL aircraft offered in the industry, it truly meets the intent of the rules for building E-AB aircraft. 

The Carbon Cub EX-3 is the kit version of the company’s popular builder-assist version of the aircraft, the Carbon Cub FX-3. It features an extraordinary thrust-to-weight ratio, thanks to the extensive use of lightweight composites, coupled with a 186-horsepower fuel-injected engine. The result is phenomenal short-field performance, a climb rate of 2,400 fpm, and exceptional handling.

The Carbon Cub EX-3 can be certified up to 2,000 pounds gross weight.
