24. Student Aircraft Builders

Student Aircraft Builders (SAB) is a student-led organization that has been building airplanes since 2013. The organization was founded by students who, sharing a passion for aviation, decided to take on the challenge of building a full-sized airplane. Over the next year, these students were able to acquire all the resources necessary to start construction of a kit aircraft, the CH STOL Zenith 750. While the initial motivation for starting this organization was to build a plane, the focus quickly moved to the educational potential of the project. The founding members realized how valuable this experience was and wanted to share it with others. A training module was established so that anyone, regardless of prior skills, could take part in the project. Students from all disciplines of engineering joined the effort. Through this, SAB has become a platform on which students develop real skills that can be leveraged in industry. Moreover, through the resource and human management demands of this project, students acquire the soft skills that are in high demand by employers. This concept has shaped our vision: through the design and construction of aircraft, SAB will stand as a source of inspiration and a vector through which students innovate, learn, and pursue their dreams. Since the origin of SAB, over 80 students have taken part in airplane construction. We truly pride ourselves in the number of students we have impacted in such a short time. In addition to the Zenith aircraft, members of SAB are actively working on the manufacturing of a Pro-Composites Vision aircraft, and an unpowered glider aircraft.
