The year 2015 was an "extraordinarily safe" one for the commercial aviation industry, the International Air Transport Association (IATA) said Monday.
In its annual assessment, IATA said the 2015 global jet accident rate - covering most large commercial airliners - was one major accident for every 3.1 million flights, a 30-per-cent improvement compared to the average over the previous five years.
There were four accidents in 2015 which resulted in 136 passenger fatalities, all of which involved turboprop - or propeller-driven - aircraft.
"In terms of the number of fatal accidents, it was an extraordinarily safe year," said Tony Tyler, IATA's director general in a press statement. “The long-term trend data show us that flying is getting even safer."
IATA say they did not include the destruction of Germanwings flight 4U9525 in March or Metrojet 9268 in October over the Sinai in its report because "they are classified as deliberate acts of unlawful interference," rather than accidents.
"While there are no easy solutions to the mental health and security issues that were exposed in these tragedies, aviation continues to work to minimize the risk that such events will happen again,” said Tyler.
