From left in July 2023: Pilots of the L-39 Albatros fighter jet, Ross Feinstein, Matt Guthmiller and Mathew Perkins stopped in Aberdeen, S.D., on their way to EAA AirVenture Oshkosh. An Albatros listed to Perkins crashed Monday in Minnesota. David Colin Dacus, 49, of San Francisco, was killed. Surviving was Mark Ryan Ruff, 43, of Dallas.

The plane that crashed in western Minnesota, killing one person aboard, was a jet fighter training aircraft that was heading to an airport near a famed world air show, according to federal regulators and a flight-tracking website.

The crash occurred about 5:30 p.m. Monday near Hwy. 23 and the Granite Falls Municipal Airport, the Yellow Medicine County Sherif’s Office said. The flight originated in Alpine, Wyo., with a final destination of Fond Du Lac County, Wis., according to FlightAware.com.

On Tuesday afternoon, the Midwest Medical Examiner’s Office identified the crash victim who died as David Colin Dacus, 49, of San Francisco. Surviving the crash was Mark Ryan Ruff, 43, of Dallas, the Sheriff’s Office said.

The Federal Aviation Administration (FAA) said the plane is registered out of Alpine, Wyo., and is a privately owned Aero Vodochody L-39 Albatros, a Czech-made aircraft used by many air forces around the world for training.

About 10 minutes before the crash, the Sheriff’s Office received a report that a jet was experiencing engine trouble near the airport.

The FAA said in its initial report that the plane “experienced engine issues, struck power lines and impacted terrain.”

First responders were dispatched and saw one person standing by the highway and was given medical attention, while the other person aboard was declared dead at the scene, the Sheriff’s Office said.

A Bloomington police bomb squad was summoned Monday night at the crash site because of “concern over the aircraft ejection seat,” said Deputy Police Chief Kimberly Clauson. “Our squad worked with others over the evening to render the aircraft equipment safe. ... Apparently, the ejection seats are powered by an under seat rocket motor, which is why the bomb squad was contacted.”

Officials have yet to say which man was piloting the plane when it crashed. Ruff is licensed with the FAA as a commercial airline pilot and is authorized to fly the model of plane that crashed, according to agency records. Dacus is also a licensed pilot, but he was authorized only to fly single-engine private aircraft, the FAA records show.

The authoritative flight-tracking website FlightAware said the plane left Alpine shortly before 11:30 MDT, stopped about an hour later in Gillette, Wyo., and arrived in Watertown, S.D., about 5:05 p.m. CDT, then crashed before reaching its destination of Fond Du Lac County in eastern Wisconsin. That’s just south of Oshkosh, where the annual Experimental Aircraft Association air show opened Monday and runs through the weekend.

Wyoming state business records show that Mathew Perkins, of suburban Salt Lake City, heads a limited liability company that owns the plane.

Aberdeen Magazine reported that Perkins and two fellow pilots landed two Albatros aircraft in eastern South Dakota in July 2023 while on their way to the air show in Oshkosh.

The FAA is being joined by the National Transportation Safety Board in the investigation of the crash.
