What happened

The airplane was in cruise flight about 2,000 feet above the ground when several witnesses reported hearing a loud "crack," "pop," or "snap" sound and then looking up and seeing something separate from the airplane and then pieces falling to the ground. The outboard 4 feet of the right wing was found about 2,000 feet away from the main wreckage, and a turkey vulture carcass was found near the wing section. Postaccident examinations of the wing section revealed blood spots and a downy barbule, which was identified as a fragment of a turkey vulture feather.
