Welcome to the San Diego Ultralight Association (SDUA) website! SDUA was formed in 1976 to support and promote ultralight and sport aviation. We are a chapter of the Experimental Aircraft Association (EAA Ultralight Chapter 114) and our mission is to help sport flying to become more accessible to all by freely sharing our combined knowledge and experience while being committed to safety and protecting the environment. We intend to have fun along the way!
Our clubhouse is on John Nichol’s Field, a private use airport in San Diego County, CA. John Nichol’s Field (0CL3) is also home to an active skydiving community.
