NTSB: Full investigation could take up to 2 years

NASHVILLE, Tenn. (WTVF) It’s day three of recovery efforts after a deadly plane crash on Percy Priest Lake this weekend.
On Monday, a barge and crane were put in the water to load up some of the wreckage. Local authorities say a number of items have surfaced, and the National Transportation Safety Board (NTSB) has taken over the investigation.
Rutherford County officials said crews were able to locate both of the engines and a significant portion of the jets fuselage. Additionally, they said more human remains were recovered, and the Rutherford County Medical Examiners Office verified that there are seven victims, four males and three females.
Investigators are working with the victims families to identify those human remains.
Crews also said the debris field expanded due to several possible factors, including but not limited to, weather and boat traffic. The recovery effort is likely to continue on Tuesday.
The NTSB said it should release its initial report in the next two weeks. However, the full crash investigation could take up to two years.
Although some of the Cessna Citation 501 is still submerged in Percy Priest Lake, former FAA inspector Larry Williams says investigators can get their hands on information about its final flight.
Williams says, in addition to specifics about the jet and man flying the plane, investigators are digging into fuel and maintenance logs, as well as the weather Saturday morning shortly before 11.
As soon as that investigation starts, they look at the background of the airplane, the pilot, he said. The weather was 1300 overcast. So, he was in the clouds at 1300 feet and that’s about the time he started to turn according to the radar track.
Williams was an FAA inspector for nearly 34 years. The type of plane that went down is also one he is licensed to fly.
Although he’s not sure what happened to send seven passengers into the water, he’s pretty certain the plane is in pieces, which is why this investigation could take a year or longer.
Unless they land on the water like Sully did, which was a miracle, it tears the airplane up, he said.
The seven people killed were all leaders at Remnant Fellowship Church in Brentwood, including The Weigh Down Workshop founder Gwen Shamblin Lara. Rutherford County officials said all indications were that William J. Lara, Gwen S. Lara, Jennifer J. Martin, David L. Martin, Jessica Walters, Jonathan Walters, and Brandon Hannah were on board the flight that originally left Smyrna airport just before 11 a.m. heading to Palm Beach International.
Families impacted by plane crash. Elizabeth Hannah was not on board.
The Lamar Boat ramp and waterway will reopen Tuesday. Fate Sanders Recreation Area will remain closed until further notice.
