The Washington state Aviation Division continues to search Thursday for a plane that failed to arrive Monday on a flight from Tonasket to Sequim (skwim).

Spokeswoman Nisha Marvel says if there are no developments officials will have to decide when to call off the search.

Eight planes with the Civil Air Patrol and Washington Air Search and Rescue flew Wednesday out of Wenatchee's Pangborn Airport. They're checking the route pilot Ed Jeffko of Tonasket would have flown.

Jeffko is the only person aboard the home-built single-engine kit plane. Marvel says there's no emergency beacon signal, radar track or flight plan.

The Wenatchee World reports Jeffko is a former Tonasket city councilman who has been active in the civil service board and economic development committee.
