This is an active investigation now in the hands of the AAIB (Air Accidents Investigation Branch), and they will be taking over as agreed.
He tweeted on Tuesday evening: "This is most welcome news from the AAIB, and now we wish the SALMO and GEO OCEAN III team has the best possible conditions for a successful recovery".
"Regardless of the results, we will not be making a further statement until the families have been informed".
British investigators said Monday they had spotted a body in the wreckage of a plane that disappeared in the Channel two weeks ago carrying Argentine footballer Emiliano Sala and his pilot.
The AAIB's vessel deployed a remote-controlled submarine to examine the plane and confirmed it was the craft carrying the striker.
Sala had plans to later arrange transport to the Welsh capital for Nala, who he rescued from an animal shelter and would regularly walk the Labrador in the vineyards of French town Carquefou, north of Nantes, which he had made his home.
A private search of the waters off Guernsey revealed wreckage of the plane, with an unidentified body inside, on the seabed off the coast of Guernsey on Sunday morning.
"At the moment we are still conducting research - all I can say is that an announcement will be made when we are able to", James Hotson, AAIB spokesman said.
"We can think that the plane did not make a fall, but rather that the pilot, perhaps following the engine stop, tried to land, which is obviously very hard to do", he told Bouchard.
He has now handed over the investigation to the AAIB who will make the decision on the next steps.
"I saw Emiliano's sister Romina in an interview after her brother's disappearance and went to the Argentinian consulate and said I thought I could help", he told the Observer.
The privately-funded operation on behalf of the Sala family came after a campaign raised more than £260,000.
In cases of disorientation, pilots may feel that their aircraft is gaining altitude while the opposite is happening, he said.
"What I know is that they only have one body, that's everything I know".
He previously said: "There's a much greater chance they [the Sala family] will get answers if [the plane is] recovered". "They are very keen but bad weather may delay that operation", he went on.
"It's a matter of will to do it", he added.
