Developed as Korea’s first hydrogen-and-battery hybrid propulsion system, this next-generation eco-friendly aircraft uses electric batteries for take-off and hydrogen fuel cells for cruise flight, achieving a new standard in sustainable aviation. Recognized as a world-first intellectual property, this model also became the first hydrogen hybrid Advanced Air Mobility (AAM) aircraft in Korea to receive Special Airworthiness Certification from the Ministry of Land, Infrastructure and Transport in 2024.

Taesang manufactures Fixed Wing Aircraft using advanced closed die forging technology with SMS Group equipment. This process ensures precision, consistency, and superior quality for critical aerospace applications

QPL certification is a system in which the US government guarantees the quality only for products that have passed strict local company inspections made of 150 tests and verifications under the supervision of the US government. Yeonhab Precision obtained the certification in Asia for the first time after 10 years of application. In particular, with the successful QPL registration for the first time in Asia, Yeonhab Precision is the first and only company in Asia which got the qualification of marking “MS” with the title of “Korea’s first MIL-DTL connector”. We will provide customers with the best products as we have the sense of the pride of developing the QPL certified connector with our own technology in Korea.
