Due to poor government control and supervision , however , aviation service deregulation provoked price wars among low-cost carriers , resulting in fierce commercial competition at the expense of poor maintenance and service breakdown . Consequently , throughout the 2000s , the number of Indonesian aviation accidents and incidents spiked tremendously . The most notable aviation accidents that occurred during this period were Lion Air Flight 583 in Surakarta ( 30 November 2004 , killing 25 ) and the Adam Air Flight 574 crash into the Makassar Strait ( 1 January 2007 , killing 107 ) . The aviation safety records in Indonesia continued to plummet in a series of flight accidents , including Garuda Indonesia Flight 421 emergency landing on the Bengawan Solo River ( 16 January 2002 , killing 1 stewardess ) , and Garuda Indonesia Flight 200 in Yogyakarta ( 7 March 2007 , killing 21 )
