Lynden Fire Chief Gary Baar says the small single-engine plane clipped trees as it approached Jansen Field from the east, causing it to plunge straight into the ground near a major street.
The pilot walked away from the wreckage with only minor injuries. He was taken to Peace Health Saint Joseph Medical Center in Bellingham as a precaution.
The single-engine Tiger Moth biplane is registered to Vern Swanson of Bellingham. Baar did not confirm if Swanson was the pilot at the controls.
Lynden police are guarding the wreck until the FAA can investigate.
