1、Designation: F2483 18Standard Practice forMaintenance and the Development of Maintenance Manualsfor Light Sport Aircraft1This standard is issued under the fixed designation F2483; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the

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

4、d with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.3 This international standard was developed in accor-dance with internationally recogni
