The Air Accidents Investigation Branch said a body has been recovered from the plane which went down in the English channel on January 21 with pilot David Ibbotson and Cardiff city new signing Emiliano Sala on board.
The wreckage of the plane, which vanished two weeks ago over the English Channel, had been found off Guernsey.
Mr Ibbotson, 59, from Crowle, North Lincolnshire, was at the controls when the flight lost contact with air traffic controllers on 21 January.
The body that was recovered from the wreckage was being taken to the Isle of Portland to be passed to the Dorset coroner. No details have been released concerning its identification. The plane was discovered through the help of specialist contractors.
Sala was travelling to Cardiff after saying goodbye to his former team-mates at Nantes, having sealed a transfer to the Premiere League in a club-record deal for the Bluebirds.
Report from the search contractors ” 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. The body is currently being taken to Portland to be passed into the care of the Dorset Coroner.
However, the AAIB said video footage captured by the ROV would provide “valuable evidence” for its safety investigation.
Its has been reported that Sala’s former club Nantes has demanded Cardiff City pay his £15m transfer fee. The fee was due to be paid over three years but Cardiff have withheld the first scheduled payment until they are satisfied with the documentation.
