The production of B737 MAX Advanced Technology Winglets requires various cutting-edge technologies, such as fabrication technique for Co-cured Blades, ultraprecision machining system and non-destructive inspection.

Korean Air has set up a task force comprising of specialists to take charge of the project and perform various tests, ensuring the maturity of technologies and identifying solutions to different problems. After years of development, Korean Air finally constructed a mass production system for the winglets.

Following the first B737 MAX winglet delivery, Korean Air will be supplying 2,400 units of B737 MAX winglets for several years.

Korean Air has played a major role in components manufacturing for both Boeing and Airbus, the world’s most famous aircraft manufacturers.
