1 International Civil Aviation Organization Airport Self-Audit Checklist (RERR 2 nd edition - Issued 2011)

2 Runway Excursion Risk Reduction Airport Self Audit Checklist Purpose Runway excursion risk factors can be directly related to airport design, operation, maintenance and operating procedures. ICAO Annex 14 Aerodromes, Volume 1 Aerodrome Design and Operations contains extensive specifications which are intended to enhance safety., When properly implemented, many of the Standards and Recommended Practises within the Annex, will provide defences against the risk of a runway excursion. This self audit checklist is provided within this toolkit as a means for airport operators to evaluate their own facilities, organisational and operational policies, procedures and programs. With the objective to assist the hazard identification process and to identify and plan for corrective actions needed to minimize risks associated with runway excursions. From the airport operator s perspective it is important to ensure that notification of deficiencies by Notice to Airmen (NOTAM) or publication in AIP is promptly initiated when required as part of a corrective action. The items in the checklist draw on lessons learned in global aviation over many years. They reflect, and comply with, the Standards and Recommended Practices of various ICAO Annexes, but particularly Annex 14 Aerodromes, Volume 1, Aerodrome Design and Operation. The checklist is intended to assist aerodrome operators and Civil Aviation Authorities to identify issues that have been shown to improve safety particularly relating to runway excursions. This self audit checklist is not intended to comprehensively cover every conceivable risk factor that may contribute to a runway excursion, nor is it intended to over-ride regulatory guidance, or manufacturer s specifications and/or maintenance requirements. Airport owners and operators are encouraged to adapt this checklist to suit their own particular airports and to modify or enhance it, as necessary, to be relevant and useful to their own particular situations. Readers and users of the guidance material should act on it only after consideration of national safety regulations and requirements, as it is not possible to provide material which will be applicable to all situations at all times. It is recommended that action be taken in respect of the material provided only in conjunction with appropriate technical advice. Although ICAO has made every effort to ensure accuracy, it shall not be held responsible for any loss or damage caused by errors, omissions, misprints, or misinterpretation of the contents hereof. Readers are invited to give their views, comments and suggestions about the contents of this document. These should be directed to the Secretary General of ICAO. 2
