International Air Transport Association director general and CEO Tony Tyler has said that over the past decade the aggregate safety results for airlines adhering to the association’s Operational Safety Audit standard are superior to those of carriers that do not use the system. His remarks came at last week’s annual African Airlines Association general assembly in Mombasa, Kenya. Tyler also said in 2012 there was not a single hull loss of a Western-built airplane by any of IATA’s 25 African member airlines.
