This number represents the all-accident rate (measured in accidents per 1 million flights) in the International Air Transport Association’s (IATA) most recent safety performance report. While not all 2016 data points met 2015 standards, the five-year average shows a positive safety trend for global commercial aviation. For example, the major jet accident rate was reported at 0.39, or one for every 2.56 million flights. In 2015, the rate was 0.32; the five-year average is 0.36.
Conclusions are based on information provided through the Global Aviation Data Management program. Trends and analysis derived from the repository of de-identified operational information are used to detect what IATA says are the biggest risks to aviation safety—controlled flight into terrain, loss of control in-flight and runway excursions—either because of their fatality rate or frequency of occurrence. Data is making a concerted effort to focus on those areas, implementing techniques that go beyond the analysis of isolated accidents and incidents and using data to identify potential risks so they can be addressed before they become safety threats.
Data utilized in the report is gathered from multiple sources and validated and classified by the Accident Classification Task Force, which is managed by IATA and comprised of industry safety experts. It meets twice a year to review, validate and classify each accident.
