The AIG Section is the custodian of Annex 13 — Aircraft Accident and Incident Investigation, providing assistance for the application and interpretation of its Standards and Recommended Practices. To this end, AIG is the ICAO Section in charge of developing policies for aircraft accident and incident investigations conducted by Member States. The sole objective of Annex 13-type investigations is the prevention of accidents and incidents and not the apportionment of blame or liability.
AIG also develops and maintains guidance material to support the investigation of aircraft accidents and incidents, as established in Annex 13.
