A body seen in the wreckage of the plane carrying footballer Emiliano Sala and pilot David Ibbotson has been "successfully recovered", investigators said.
Remotely operated vehicles (ROVs) were used in "challenging conditions" to pull the body out of the water "in as dignified a way as possible" the Air Accidents Investigation Branch (AAIB) said.
The body is being taken to the island of Portland to be passed over to the Dorset coroner for examination, the AAIB added.
The aircraft remains 67 metres underwater 21 miles off the coast of Guernsey in the English Channel as poor weather conditions stopped efforts to recover it.
An AAIB spokesman said: "Unfortunately, attempts to recover the aircraft wreckage were unsuccessful before poor weather conditions forced us to return the ROV to the ship.
"The weather forecast is poor for the foreseeable future and so the difficult decision was taken to bring the overall operation to a close.
"In challenging conditions, the AAIB and its specialist contractors successfully recovered the body previously seen amidst the wreckage.
"The operation was carried out in as dignified a way as possible and the families were kept informed of progress."
The remains of the plane were discovered on Sunday evening. It had disappeared on 21 January as it travelled from Nantes in France to Cardiff.
The AAIB said previously that the work of the ROVs has been hampered by the difficult tidal conditions around the Channel Islands.
The plane had requested to descend before it lost contact with Jersey air traffic control.
An official search operation was called off on 24 January after Guernsey's harbour master David Barker said the chances of survival following such a long period were "extremely remote".
The remains of the aircraft were tracked down by a team co-ordinated by ocean scientist David Mearns, who has located some of the most elusive wrecks in the world.
Mr Mearns and his team located the aircraft within two hours of commencing their search.
He said the discovery had been so quick because the team had been looking for a static object rather than in a dynamic environment searching for survivors.
The AAIB said it expected to publish an interim report within the month.
