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. Search in the Title: box by keywords, models and/or issue date, the Category: box by subject or the all-fields Search: box to find relevant documents. For example, the all-fields search “Maint 199” will return all rows with the keyword “maint” and issue or revision dates before year 2000.
