ATLANTA—A CFM Leap-1B engine made out of Lego bricks is making its worldwide public debut on April 18 at Lufthansa Technik’s booth (#1421) at MRO Americas.

The engine, built at 60% of the powerplant's actual size, is made of some 400,000 Lego pieces and weighs 450 kg (992 lb.). It measures 105.6 cm by 1.88 cm by 145 cm.

The idea came from a Lufthansa Technik employee who likes to build things out of Lego and his son, “who built the first Lego engines at a smaller scale for giveaways,” says Derrick Siebert, Lufthansa Technik’s VP of commercial engine services. “These were very well received from customers, and that is where the idea generated,” he adds.
