Sioux Lookout Area Plane Crash Update

The cause of a fatal plane crash north of Sioux Lookout last month has become a complicated puzzle.
Transportation Safety Board Official Peter Hildebrand says there are no witnesses or flight recorders which is hindering their investigation.
He says they are looking at the fittings that attach the wing to the plane to see if that may be a problem area.
Parts of the plane have been sent to a lab for analysis.
Hildebrand says it could be a couple of months before testing is done and a preliminary report is released.
The aircraft, owned by Pickerel Arm Camps, went down on May 18th on Fawcett Lake killing all 4 people on board.
