AMC M.A.802 Component certificate of release to service
CAA ORS9 Decision No. 1
The purpose of the CAA Form 1 (see also Appendix II to Part-M) is to release components after manufacture and to release maintenance work carried out on such components under the approval of a CAA, and to allow components that are removed from one aircraft/component to be fitted to another aircraft/component.
When an approved organisation maintains an aircraft component for use by the organisation, a CAA Form 1 may not be necessary depending upon the organisation’s internal release procedures; however all the information normally required for the CAA Form 1 should be adequately detailed in the certificate of release to service.
