2012 Accident Statistics

As its primary indicator of aggregate safety in the global air transport sector, ICAO studies the accident rate based on scheduled commercial operations involving aircraft having a maximum take-off weight (MTOW) above 2250 kg. Aircraft accidents are categorized using the definition provided in Annex 13 to the Chicago Convention—Aircraft Accident and Incident Investigation. Exposure data is comprised of scheduled commercial operations that involve the transportation of passengers, cargo and mail for remuneration or hire.
The chart below shows the change in the accident rate over the previous seven years, with 2012 having an accident rate of 3.2 accidents per million departures, the lowest recorded since ICAO began tracking the global accident rate. In addition to the global accident rate as calculated historically, ICAO is committed to working with its partners through the Global Safety Information Exchange (GSIE) to develop a harmonized accident rate based on common criteria. Details on the GSIE harmonized accident rate can be found later in this report.


Regional Accident Statistics

To further analyze the state of aviation safety, the accident data for scheduled commercial air transport is categorized according to United Nations regions, based on the state of occurrence for each accident. The table on the next page provides insight into the state of aviation safety in different regions in the context of global outcomes. While Africa had the highest regional accident rate, it also accounted for the lowest percentage of global traffic volume, about 3 per cent of scheduled commercial traffic. However, it should be noted that for the second consecutive year, none of the regional accident rates were greater than twice the global rate.

Accident Statistics and Accident Rates: 2012


The distribution of accidents, fatal accidents and fatalities by region is shown in the table above. While Africa accounted for only 5 per cent of total accidents, 45 per cent of all fatalities occurred in that region. Northern America experienced no fatal accidents while no accidents at all occurred in Oceania in 2012.
