- Annex 13 of ICAO to form the base of the investigation
Seattle.12 June 2025 . The following is a statement from Boeing [NYSE:BA] President and CEO Kelly Ortberg about Air India Flight 171.
Boeing President and CEO Kelly Ortberg said, “Our deepest condolences go out to the loved ones of the passengers and crew on board Air India Flight 171, as well as everyone affected in Ahmedabad. I have spoken with Air India Chairman N. Chandrasekaran to offer our full support, and a Boeing team stands ready to support the investigation led by India’s Aircraft Accident Investigation Bureau.”
Boeing will defer to India’s Aircraft Accident Investigation Bureau (AAIB) to provide information about Air India Flight 171, in adherence with the United Nations International Civil Aviation Organization protocol known as Annex 13.
Annex 13 defines an accident as an occurrence associated with the operation of an aircraft: in which a person is fatally or seriously injured; in which an aircraft sustains damage or structural failure requiring repairs; after which the aircraft in question is classified as being missing. According to the provisions laid down in ICAO Annex 13 to the International Civil Aviation Convention – Aircraft Accident and Incident Investigation, States shall investigate or delegate the investigation of accidents which have occurred in their territory. Serious incidents should be investigated by States or by other organizations, such as dedicated accident/incident investigation bodies or aviation service provider organizations. When an accident happens to involve an international civil aviation flight, Annex 13 sets out the rules on the notification, investigation and reporting of the accident.
Annex 13 outlines how accident investigation participating States are determined, as well as the process leading to the issuance of an accident investigation Preliminary Report (within 30 days of the event) and Final Report (ASAP or within 12 months of the event) following completion of the investigation. Final Reports ultimately provide as much official information as possible on an accident investigation’s findings, causes and/or contributing factors, as well as any safety recommendations on how applicable aviation safety frameworks should be amended in the future. It sets out the rights on who should conduct the investigation, which are the parties who can be involved, what right dues each party has, how should the investigation be conducted, and how the final results should be reported. Annex 13 also states that the sole objective of the investigation of an accident or incident is to prevent accidents and incidents and that the investigation is not to apportion blame or liability.
ICAO does not normally participate in aircraft accident investigations, except when the State or States with due authority under Annex 13 request assistance directly; in those exceptional circumstances, assistance normally involves ICAO acting as an official observer and/or clarifying various Annex 13 requirements when requested.
