WSDOT searching for missing plane near Snoqualmie Pass

OLYMPIA - The Washington State Department of Transportation is searching for a missing plane in the vicinity of Interstate 90 near Snoqualmie Pass.

WSDOT Air Search and Rescue was notified Sunday evening of a missing 2001 Extra Flugzeugbau 300/L piloted by Jerry Riedinger. Riedinger left the Arlington Municipal Airport Sunday at 4:30 p.m. Riedinger’s wife reported him missing around 6 p.m., after he did not arrive at his destination in Ephrata. An air search is underway and includes assistance from King County Search and Rescue and the King County Sheriff's Office on the ground.

The pilot was reportedly carrying a parachute, and the aircraft was equipped with a new 406MHz Emergency Locator Transmitter. There has been no communication from the aircraft and no emergency beacon signals received. Riedinger was the only known occupant.

Search efforts will continue through the night and WSDOT Air Search and Rescue will resume efforts Monday, May 20. Anyone who thinks they saw or heard the plane Sunday or spotted anything in the area should call the State Emergency Operations Center at 800-258-5990 with details. At this time, search officials do not need volunteers to conduct air or land searches.

Updates on the search will be posted on the WSDOT blog. Email updates from WSDOT are also available online by signing up and selecting the emergency news "air search and rescue" option. Barring new developments – which would be announced on the blog – the next update is planned for 11 a.m. Monday, May 20.
