How does ICAO choose the "official" set of accidents every year?

ICAO's global accident rate provides an overall indicator of safety performance for air transport operations. The accident rate is based on scheduled commercial operations involving fixed-wing aircraft with a certified MTOW over 5,700 kg. Aircraft accidents are reviewed and validated by the ICAO Occurrence Validation Study Group (OVSG) using definitions provided in Annex 13 — Aircraft Accident and Incident Investigation.

Data on departures is collated by ICAO's Air Transport Bureau and comprises scheduled commercial operations that involve the transportation of passengers, cargo, and mail for remuneration. Estimates are made where data has not been provided by States, and as new data is provided to ICAO, it will be incorporated into the database. It is worth noting that this may cause slight changes to the calculated rates from year to year.
