The Australian Tranportation Safety Bureau (ATSB) released its annual report on aviation occurrence statistics.
In 2013, there were 106 accidents, 221 serious incidents, and about 5,500 incidents reported to the ATSB involving Australian aircraft. There were also 71 accidents, 33 serious incidents, and 137 incidents involving Australian recreational aircraft and a further 200 foreign-registered aircraft operating within Australia or its airspace were involved in reportable safety occurrences.
Over the past 9 years, recreational aeroplane, aerial agriculture and private/business/sport operations had the most accidents per hour flown, with more than 160 accidents per million hours flown. Gyrocopters (recreational aviation) had the highest fatal accident rate over this period, followed by recreational aeroplane and private/business operations.
Commercial air transport aircraft were involved in the majority of occurrences, and in 2013 the most common occurrences reported were wildlife strikes, weather affecting aircraft, and aircraft system problems. Most accidents and serious incidents involved reduced aircraft separation, engine malfunction, or runway excursions. The number of incidents reported by commercial air transport operators has increased in each of the last 10 years, reflecting more flights and greater awareness of the importance of reporting safety occurrences.
