The Air Accident Investigation Authority (AAIA) is responsible for investigating civil aviation accidents in Hong Kong, as well as those in other territories involving a Hong Kong-registered aircraft. It is led by Darren Straker, Chief Inspector of Accidents, and headquartered at Hong Kong International Airport. AAIA was established in 2018 in response to an ICAO directive instructing that member states maintain air accident investigation authorities that are independent of civil aviation authorities and related entities.
