Tech Bulletins

Hang Gliders require routine maintenance to meet the airworthiness standards to which they were developed and are sometimes subject to airworthiness advisories for inspection, configuration and maintenance. We strongly encourage all pilots of Wills Wing gliders to review all Technical Bulletins that are applicable to their equipment and check this page periodically for updates.

Tech Bulletins are titled with the prefix “TB” followed by 8 digits representing the issued date as YYYYMMDD.
