Investigators on Monday will attempt to remove the wreckage of a plane that crashed into Lake Harney in Seminole County.

The plane went down on Friday and three bodies were recovered over the weekend.

Divers have been out over the weekend not only to recover those bodies but dealing with nearly zero visibility as they attempt to find the pieces of that plane, a Beech C-90 twin-engine aircraft.

Investigators with the National Transportation Safety Board (NTSB) are still trying to figure out what brought the plane down.

Officials say the tower at the Orlando Sanford International airport lost radio communication with the pilot, 56-year-old Sanford resident Kamahlesh Naik, but at this point, there were no maydays or distress calls received.

Officials say the plane is just 10 feet underwater and are using sonar to find it.

However, it is taking longer than expected to retrieve it because the water is so murky.

"It's a fairly complex situation right now due to the underwater visibility. The divers that have been going under the water report 5 to 8 inches of visibility. So with that limited visibility it hampers our effort to figure out where the rest of the airplane is," said Joshua Cawthra, a senior aviation accident investigator with the NTSB.

The bodies of Naik and two trainees from China were recovered Saturday.

Once the recovery of the aircraft is complete, the NTSB will examine the wreckage to conclude what brought that plane down.
