Federal investigators are focusing on one of the wings of the seaplane that crashed on the Willamette River last Saturday. Witnesses said the wing fell off the plane seconds before it crashed into the Willamette River last Saturday.

The crash killed 80-year-old David Wiley and 52-year-old Scott Forsberg.

Mayer said Forsberg was a certified float plane pilot who was here acruing some flying hours. He said he was not able to determine if Forsberg was the pilot of the plane when it crashed. His family said Forsberg wanted to be a pilot when he was a little boy.

Wiley was an accomplished flight instructor and a former National Seaplane Pilot of the Year.

The two men were killed shortly before noon last Saturday when Wiley's vintage 1941 Taylorcraft float plane crashed just north of Willamette Falls, which lies betwee Oregon City and West Linn.

Clackamas County sheriff's spokesman Jim Strovink said people who saw the crash told him the plane took off in an "unstable fashion." It was unclear if Wiley, a certified instructor and mechanic who runs Wiley's Seaplanes, was piloting the plane.

"The family wishes to extend their sincere appreciation and deep gratitude for the enormous outpouring of support. Following a private memorial service there will be a public gathering."

In 2000, Wiley, an aviation safety counselor for the Portland Flight Standards Division Office, was designated a master certified flight instructor by the National Association of Flight Instructors.

At the time, he was one of only two Oregonians and one of fewer than 200 of the 78,000 certified flight instructors in the United States to achieve the distinction signifying an expertise beyond minimum standards mandated by industry and government.

He was named National Seaplane Pilot of the Year in 1999.

His family has set up a scholarship fund in his name. Relatives encourage people to donate to the "Dave Wiley Memorial Scholarship Fund" at any US Bank Branch. The funds will help support young students who want to learn how to fly planes.

An investigator with the National Transportation Security Board said the investigation should take six months.
