This handbook is intended to provide detailed instructions for [State CAA] staff to conduct air operator certification, surveillance and resolution of safety issues. It is divided into three volumes: Volume I outlines the policy and procedures to be followed by [State CAA] and operators for the initial issuance of an AOC; Volume II outlines the policies and procedures related to operational demonstrations, inspections, approvals and surveillance; while Volume III contains policies and procedures for airworthiness inspections, approvals and surveillance. Many of the inspections required for the initial certification of an air operator will subsequently be repeated during the implementation of [State CAA] surveillance programme.
