Their were a total of 68 accidents, fatal and non fatal, in 2015 down from 77 in 2014.
"In terms of the number of fatal accidents, it was an extraordinarily safe year," said IATA Director General Tony Tyler.
The 2015 accident statistics do not include two major airline disasters that were caused intentionally.
The deliberate crash of Germanwings 9525 by its pilot and the suspected terrorist attack on Metrojet 9268 resulted in the deaths of 374 passengers and crew.
