MARYSVILLE, Washington -- Authorities say one person died Wednesday after a small plane crashed into a rural Marysville field.

Marysville Police say the single-engine plane went down around 7 p.m. along the 15700 block of 51st Ave, just about two miles from Arlington Municipal Airport.

The person who died was the only one on board the plane at the time of the crash, officials said. The aircraft could be seen strewn across a field, broken and shredded into multiple pieces.

The NTSB is investigating the crash and told Q13 News the airplane that crashed was experimental amateur-built.

Multiple witnesses on the ground said they saw the aircraft passing overhead at a low altitude.

“I live in the flight line and see a lot of planes every day,” said witness Cody Woodward. “I was sitting in my front yard and I heard the engine pop and rev high.”

“All of the sudden I heard a really loud sound,” said witness Melissa Frenzel. “It sounded like a loud lawn mower and I looked up and saw a really low plane. I was like, that was odd.”

The NTSB says a preliminary report could be released within a few days but a full report could take six months or up to two years to complete.

An official from the agency is urging anyone who witnessed the crash but has not yet to reached out to law enforcement to do so.

The aircraft's tail number and the identity of the pilot has not yet been released.

This crash marks the third small plane crash in western Washington this month.

  1. Not familiar with the engine type ... Eastern European?


  2. The Vedeneyev M14P is a Russian nine-cylinder, four-stroke, air-cooled, petrol-powered radial engine. Producing 360 hp (268 kW), its design dates from the 1940s (Kotelnikov 2005), and is itself a development of the Ivchenko AI-14 engine. The engine has been used extensively by the Yakovlev and Sukhoi Design Bureaus.

  3. Thanks ... Most of our US engines originated in the 40's as well.

    May he RIP.
