2、 year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice provides guidelines for the qualificationsto accomplish the various levels of maintenance on U.

3、S.-certificated experimental and special light sport aircraft. Inaddition, it provides the content and structure of maintenancemanuals for aircraft and their components that are operated aslight sport aircraft.1.2 This standard does not purport to address all of thesafety concerns, if any, associate
