The Air Accidents Investigation Branch have published new set of pictures from the crashed plane of late Emiliano Salah.
The Argentine forward joined Cardiff City from French League side Nantes during the January transfer window.
However, he was unable to kick a ball for the Premier League side after the plane transporting him to his new club crashed into the English Channel in January.
Both Sala and David Ibbotson, who was the pilot of the Piper Malibu plane died in the process of their movement from France to England last month.
According to SunSport, the US-registered plane did not have approval to be flown commercially and had not sought permission to do so, while the pilot
The publication also claim Ibbotson is confirmed to have held a private pilot's licence - but not a commercial one.
"[The plane] was registered in the USA and could not be used for commercial operations without permission from the FAA and CAA." the statement said.
"At the time of writing there was no evidence that such permission had been sought or granted.
"To fly an aircraft registered in the USA between EASA Member States, a pilot must operate using the privileges of an FAA licence."
After preliminary investigations, the plane crashed at the rate of around 7,000ft-a-minute after twice requesting permission to descend in order to gain better visibility in heavy fog.
In its final seconds, the report says radar signals suggest the plane climbed rapidly from around 1,600ft to about 2,300ft.
Reports also revealed that Ibbotson did not use flight instruments that were vital to flying through cloudy conditions on the night of the doomed flight to Cardiff.
While he was reported to have filled the Malibu-Piper aircraft's licence number incorrectly on his flight plan form as reported by Argentinian journalist Christian Martin.
Mr Ibbotson said shortly after arriving in France: "Was not to (sic) bad when I got there but I'm a bit rusty with the ils, in France now. " A friend replied: "Rusty with the ILS?! I can't believe that !"
Mr Ibbotson added: "You wanna bet, a little on the high side hehe, better than on the low side."
Sala arrived at the airport at 6.36pm on the night of January 21 and the flight took off exactly half an hour later.
