CHEHALIS, Wash. -- Two helicopters searched without success Monday for a light plane carrying three people that reported an engine problem in southwest Washington.

A spokeswoman for the Washington State Aviation Division says the choppers flew in rainy, windy weather between White Pass and Chehalis.

The plane dropped off radar about 7:45 a.m. Monday in mountainous terrain in the Morton-Packwood area.

The pilot and two passengers have not been identified.

An FAA spokesman says the pilot of the Cessna 340A reported losing power in one of two engines about 10 minutes after taking off from Chehalis for Lewiston, Idaho.

The plane is registered to Pacific Cataract and Laser Institute in Chehalis.
