On August 20, 2026, a twin-engine turboprop Cessna 441 Conquest II, operated by Anchorage-based charter operator Security Aviation, crashed near a remote military installation in southwest Alaska, resulting in the deaths of all eight people aboard. The flight was an on-demand charter contracted by the U.S. Army Corps of Engineers to transport personnel on an official infrastructure assessment and mission support assignment.
The flight originated from Ted Stevens Anchorage International Airport and was destined for the Cape Newenham Long Range Radar Site Airport, located approximately 450 miles southwest of Anchorage on the edge of the Bering Sea. The airstrip serves a Pacific Air Forces Regional Support Center installation situated on the slope of a 2,300-foot mountain, utilized by the military to monitor Alaskan airspace and regional border corridors.
The aircraft was carrying two pilots and six passengers, including two civilian employees from the Alaska District of the U.S. Army Corps of Engineers. At approximately 12:15 PM local time, while on approach to Cape Newenham in conditions characterized by dense fog, low ceilings, and visibility reported at less than 800 feet, the aircraft impacted terrain west of the airfield. Search and rescue teams coordinated by Alaskan Command, the Rescue Coordination Center, and the U.S. Coast Guard responded to the site and confirmed there were no survivors. The National Transportation Safety Board is leading the investigation with assistance from the Federal Aviation Administration.
