The Air Accidents Investigation Branch searching for Sala’s plane has come out to say the seat cushion belonging to the plane has been found on a beach.
The items were spotted near Surtainville on the Colentin Peninsula in the north of France during the under water search.
An underwater search of four square miles would be done by the AAIB on its known flight path and known radar positions.
The search is expected to start this weekend and is likely to last for three days.
A private air and sea rescue mission is also being conducted after more than €300,000 were raised by a GoFundMe campaign.
The AAIB search is separate from the private search, but they are now liaising with each other.
