ALBANY, Ore. (AP) A preliminary report on the investigation of the crash of a light plane last week near Albany says a witness saw one wing fold upward during a turn, and the wing apparently hit the canopy, shattering its glass.
The Albany Democrat-Herald reports there was an area of glass shards between the wing, found on Oregon 226, and the rest of the wreckage about 1,000 feet south.
The brief document from the National Transportation Safety Board didn't say why the wing detached from the plane.
Van McKenny, an aerospace engineer with the agency, said experts will examine the plane later this month. A final report may take a year.
Timothy Dean Carter, 46, of Portland and Jeff Earl Kropf, 45, of Halsey died in the crash.
The plane's manufacturer said it was built from its plans and heavily modified.
