Investigation Summary
The aircraft, a former U.S. Marine Corps KC-130R refurbished to C-130H standards, was on a routine monthly logistical mission. It departed Punta Arenas at 16:53 local time. At 18:13 local time, while cruising over the notoriously turbulent Drake Passage, all contact was lost. The lack of a distress call suggested a sudden, catastrophic failure that left the crew no time to react or communicate. Search teams from Chile, Argentina, Brazil, the United Kingdom, and the United States faced extreme weather conditions, including rough seas and poor visibility. On December 11, the Brazilian research vessel Almirante Maximiano recovered the first pieces of floating debris, including sponge-like material likely from the fuel tanks, approximately 31 kilometers from the last known position. On December 12, the search area was refined and the main wreckage field/impact zone was located approximately 27 kilometers from the last known position. Subsequent recovery of landing gear components and fuselage sections confirmed a high-impact water entry or mid-air disintegration.
Final Conclusions
The investigation conducted by the Chilean Air Force was hampered by the depth of the ocean in the Drake Passage and the limited amount of wreckage recovered. While the aircraft underwent a complete structural break-up, investigators could not definitively determine if the failure occurred in flight or upon impact with the water. As of the latest official updates, the specific trigger for the accident, whether mechanical, structural, or environmental, remains unknown.
