NOTE: This is a controlled and restricted publication. The latest revision of this publication is with the Directorate of Airworthiness Standards (DAWS) of the NCAA. This advisory circular (AC) provides all aircraft operators with information and guidance for assistance in compliance to Nig. CARs Part 5 on mandatory continuing airworthiness information. The recommendations contained in this AC are one means, but not the only means, of complying with Part 5 requirements pertaining to Airworthiness Directives (AD). However, individual operations and needs should determine an operator’s AD management process. When developing an AD management process, operators should consider its size, capabilities, resources, and equipment. The operator’s AD management process should be documented in their Maintenance Control Manual (MCM) or Continuing Airworthiness Management Exposition (CAME).
