The crash site – a rural area only reachable by a 30-minute ATV drive – is not ideal for investigators.
"We have got a fairly large team," NTSB investigator Tom Latson said. "At this time, we have three FAA inspectors on scene and three accident investigators from the aircraft manufacturer."
The NTSB also has a meteorologist on hand to monitor weather conditions.
The issue now comes down to the best way to get the wreckage back to a hanger in Dallas for further inspection. The cause may not be determined for 12 to 18 months. There should be a preliminary report on the NTSB website sometime in the next weeks.
The wreckage may be removed by Monday, officials said.
