Air Accident Investigators are attempting to recover the body found in the wreckage of the plane that was carrying Emiliano Sala and his pilot David Ibbotson.
The AAIB says if that is successful, it will consider whether to recover the stricken aircraft.
Only the Cardiff City footballer and David Ibbotson were on board the plane.
The light aircraft was found in the English Channel on Sunday - nearly two weeks after it dropped off the radar.
In a statement, an An Air Accidents Investigation Branch spokesperson said:
"We are attempting to recover the body. If we are successful, we will consider the feasibility of recovering the aircraft wreckage.
"Strong tidal conditions mean we can only use the remotely operated vehicle (ROV) for limited periods each day and this will mean that progress is slow. Regardless of results, we will not be making a further statement until the families have been informed."
