Marine scientist David Mearns, who directed a privately-funded search operation north of Guernsey on behalf of the Sala family, said the wreckage of the plane was "located earlier this morning".
Pilot David Ibbotson, the other man on board, was taking Sala to Cardiff where he was to start playing for his new club in the Premier League after signing from French club Nantes.
Cushions believed to be from the aircraft were found on a beach near Surtainville, on the Cotentin Peninsula in France, on Monday last week.

And Sky News reporter Tom Parmenter has reported that the plane has been located on the seabed. "We think we have got double the chance of finding something".
"I just thought the whole club was unbelievable".
"I was the proudest man to be manager of the whole club today, because the fans were just wonderful".

Sala's name was sung throughout a game which Cardiff won with a Bobby Reid double.
"The crowd were incredible and it's been a very emotional 10 days", Cardiff boss Warnock told BT Sport.
