Overseas Territories Aviation Circulars are issued to provide advice, guidance and information on standards, practices and procedures necessary to support Overseas Territory Aviation Requirements. They are not in themselves law but may amplify a provision of the Air Navigation (Overseas Territories) Order or provide practical guidance on meeting a requirement contained in the Overseas Territories Aviation Requirements.
This Circular provides guidance, to applicants for the preparation of the data required to support applications for the approval of design changes (modifications) to aircraft in compliance with the Air Navigation (Overseas Territories) Order and OTAR Part 21.
This Circular relates to OTAR Part 21 and, insofar as a design change may affect noise certification, OTAR Part 36.
Enquiries regarding the content of this Circular should be addressed to Air Safety Support International at the address on the ASSI website www.airsafety.aero, or to the appropriate Overseas Territory Aviation Authority.
