An Indonesian Air Transport ATR 42-500 turboprop aircraft, reportedly chartered by the Ministry of Marine Affairs and Fisheries for aerial surveillance, crashed in the Bantimurung-Bulusaraung National Park, South Sulawesi. The plane, carrying 11 people—consisting of eight crew members and three ministry officials—lost contact with air traffic control on Saturday afternoon, January 17, 2026, while flying from Yogyakarta to Makassar. Rescue teams successfully located scattered wreckage, including parts of the fuselage, tail section, and windows, on Sunday, January 18, 2026. The crash site is situated in a rugged, mountainous area near Mount Bulusaraung, and rescue efforts are severely hampered by the challenging terrain and persistent dense fog, limiting visibility for both ground and aerial units. Over 1,000 personnel, including the air force, police, search and rescue agencies, and local volunteers, are engaged in the extensive search and rescue operation, with the primary objective of locating the missing individuals. Officials have expressed hope for finding survivors, despite the difficult conditions. The incident has once again brought attention to Indonesia's aviation safety record, given the country's reliance on air transport across its vast archipelago and its history of aviation accidents. The National Transportation Safety Committee (KNKT) has initiated data collection for an investigation into the cause of the crash.
