This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
On November 18, 2018, at 2240 central standard time, a Cessna 441, N441CX, was destroyed when it broke up in-flight and impacted an open field near Harmon, North Dakota. The airline transport certificated pilot, flight nurse, and paramedic were fatally injured. The airplane was registered to and operated by Bismarck Air Medical under the provisions of Title 14 Code of Federal Regulations Part 135. Visual meteorological conditions prevailed at the time of the accident, and an instrument flight rules (IFR) flight plan had been filed for the air medical cross-country flight. The flight originated from Bismarck Municipal Airport (BIS), Bismarck, North Dakota, at 2230, and was en route to Sloulin Field International Airport (ISN), Williston, North Dakota.
Preliminary information indicated the crew was en route to ISN to pick up a neonatal infant for transport back to BIS. Radar data indicated the airplane climbed on a direct course until reaching 14,000 feet above sera level. Ground speed was at 240 knots. The airplane then entered a steep right bank and radar contact was lost. No distress calls were received.
Wreckage was scattered for about 1 mile long and 600 feet wide on snow-covered terrain. The cockpit area, cabin area, empennage, both engines and propellers, and both wings were identified and recovered. Flight control continuity was established.
