NASHVILLE, Tenn. (WTVF) – It’s the third day of the rescue effort after a fatal plane crash at Percy Priest Lake this weekend.

On Monday, a barge and crane were put into the water to load part of the wreck. Local authorities say a number of items have surfaced, and the National Transportation Safety Board (NTSB) has taken the investigation.

The NTSB said it should release its first report within the next two weeks. However, it could take up to two years to fully investigate the crash.

In addition to details about the jet and the man who controls the plane, investigators dig into fuel and maintenance logs, as well as into the weather on Saturday morning just before 11 a.m.

Although part 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 most recent flight.

“As soon as this investigation begins, look at the background of the plane, the pilot,” he said.

Williams was an FAA inspector for nearly 34 years. The type of plane that crashed is also one he has a license for.

While he’s not sure what sent seven passengers into the water, he’s pretty sure the plane was torn to pieces, which is why this investigation could take a year or more.

“If you don’t land on the water like Sully, which was a miracle, it’ll tear the plane apart,” he said.

The seven people killed were all leaders of the Remnant Fellowship Church in Brentwood, including the founder of the Weigh Down Workshop, Gwen Shamblin Lara.
