The National Transportation Safety Board recovered and identified more parts of the Learjet 60 that slammed into the ground on Nov. 1 in Palm Beach County, Florida. 

Investigators have recovered both wings, both engines, the flight deck, and parts of the tail section, as well as other control surfaces, the NTSB announced in a post on X on Sunday. 

Some of the parts have been sent to Washington, D.C. for closer inspection, the NTSB said. 

Federal investigators found three pieces of the jet's left elevator between 1.3 and 3.8 miles from the impact site in Palm Beach County, Florida, a few days after the crash, which killed all nine people on board. 

The NTSB is asking the public to contact the agency if they find any more parts of the aircraft. 

"Please do not keep it or attempt to move, alter or dispose of it," the agency said. 

The NTSB has said the investigation will be complicated and take a long time, due in part to the near-total destruction of the plane.
