The pilot, Ed Busch of Anacortes, was taken to Island Hospital with a possible head injury and later transferred to Harborview Medical Center in Seattle.
The accident happened shortly before 3pm Saturday as the pilot reportedly attempted a landing, but clipped power lines. The plane was reported to have taken off from an airport in the San Juan Islands.
The Skagit Valley Herald said the plane is registered to an Anacortes aircraft sales and leasing company.
