Effective: on issue


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.


Aerodromes are required to hold a certificate if they are to conduct certain types of flight operations. An aerodrome certificate is issued to a certificate holder, normally an aerodrome operating company, on successful completion of the certification process. Once an aerodrome certificate is issued, the certificate holder has an obligation to maintain compliance with laws and regulations to ensure the aerodrome certificate is not suspended or revoked. To assess compliance with laws and regulations, Aerodrome Inspectors of Air Safety Support International (ASSI) or the designated Overseas Territories Aviation Authority (OTAA) will undertake visits to the aerodrome, both for initial certification and continuing compliance. This circular provides guidance on the conduct of such visits.


OTAR Parts 139, 140 and, where applicable, 178.


The fourth issue has been revised and updated to include new reference guidance for applicants.


Enquiries regarding the content of this Circular should be addressed to Air Safety Support International at the address on the ASSI website or to the appropriate Overseas Territory Aviation Authority.
