It's expected to take a couple of hours to remove the plane.
Jason Adamae, with the FAA, says the pilot Ray Martin is in serious condition at a hospital in Shreveport.
The crash happened just before 11 a.m. on Tuesday.
The McDonald's restaurant remains closed.
Monroe -- FAA officials arrived at the scene Tuesday evening of the plane crash in a McDonald's parking lot in Monroe.
Near 10 p.m. that night, fuel started leaking again, but crews who have remained on the scene are using sand to keep it contained. Sand has also been spread near Desiard to keep any liquids from leaking toward the street.
The officials are there to assess the plane, which is still upside down, and see what they can find out about what caused the crash. Firefighters still don't expect to be able to move the plane until Wednesday morning.
The crash happened just before 11 a.m. Tuesday at the McDonald's located on 8023 Desiard Street in the Lakeshore area.
According to Louisiana State Police, the pilot was airlifted to a hospital in Shreveport to be treated for moderate injuries, including a broken leg.
According to KTVE/KARD's Nick Lawton, Desiard Street is completely reopened. Highway 80 is also now open to all traffic. Balboa Street surround the scene is still blocked off.
The McDonald's restaurant is also still closed and roped off with the crashed plane still in the parking lot.
Onlookers have been pulling up in droves to take pictures of the plane. Deputies will be monitoring the scene all night to prevent anyone from disturbing the wreckage.
The firetruck from Monroe Regional Airport is also required to be on the scene for 12 hours in case of flare ups, officials say.
The plane, a single engine Beechcraft Bonanza, is registered to WFO Flying Service out of Carmi, IL. According to Greg Brown from Brown's Feed & Chemical, Michael Ray Martin, 41, of Calhoun, was piloting the plane when it crashed this morning.
Brown says the plane never originated from Carmi, Illinois and has been at the Monroe Regional Airport since November 2013.
Brown says Martin was taking part in a test flight after repairs were made on the plane after some mechanical issues. Martin told deputies that engine quit on him while in the air, according to officials.
Officials say Martin was the only occupant on board.
According to witnesses on the scene, the plane was flying east along Balboa Street when it clipped the top of a tree, spun and crashed into the parking lot.
No injuries on the ground were reported. A parked car was damaged in the crash.
Entergy fixed a transformer that was clipped as the plane came down.
NTSB has been notified and will investigate the exact cause of the crash.
LSP also says there is no immediate threat to public safety.
This is also the same McDonald's that was robbed at gunpoint on Sunday morning.
