Number of AOC 121 and AOC 135 Aircraft in Indonesia

Flight operator performance is assessed through the issuance of certified flight licenses. Aircraft with a passenger capacity exceeding 30 seats are categorized under Air Operator Certificate (AOC) 121, while aircraft with a capacity of less than 30 seats or chartered flights are designated as AOC 135. Several airlines, such as Garuda Indonesia, Merpati Nusantara Airlines, and Sriwijaya Air, fall under the AOC 121 category, whereas Travira Utama and Airfast Indonesia are AOC 135 operators.

Data from the Directorate General of Air Transportation shows that the number of aircraft certified with AOC 121 and AOC 135 in Indonesia totaled 891 in 2017. This indicates a decrease from the previous year's figure of 903 aircraft. Historically, between 2013 and 2017, the number of aircraft with AOC certification saw the most significant increase in 2015, rising by 8.17% to 887 aircraft.

The government aims to achieve an air transportation accident ratio of less than 3 incidents per 1 million flight cycles for AOC 121 and AOC 135 in 2019. Furthermore, the government has implemented a ban on carrying certain products on AOC 121 and AOC 135 aircraft to prevent fire hazards, such as the 15-inch Macbook Pro.
