The investigation is set to begin Wednesday into what caused a plane crash that killed two people.
Searchers finally found the wreckage of the small, twin-engine plane in Western Leslie County, near the Clay County line, Tuesday night.
The plane is a Beechcraft Baron, which seats about four people.
Searchers spotted the plane from the air and got to the remote site using ATVs and chainsaws.
It was on its way from Maryland to Mississippi.
No one is believed to have survived.
The NTSB and FAA are investigating.
