Air accident investigators are dismantling the wreckage of a plane which crashed at Cork Airport, killing six people.
The cockpit voice recorder and flight data recorder, the black box, are being sent to laboratories in Dublin and Farnborough, Hampshire, for inspectors to recreate the final minutes of the doomed flight.
At least 16 investigators from Ireland, the UK, the US and Spain are working side by side on the inquiry led by the Air Accident Investigation Unit (AAIU).
Jurgen Whyte, AAIU chief inspector, said initial surveys and measurements have been taken and teams on site are planning to clear the wreckage.
"Investigators have done a survey of the site. The wreckage is generally confined to one area," he said.
"They are in the process now of dismantling the aircraft, maybe cutting segments off the aircraft, so that it can be transported."
The wreckage will be examined further at the AAIU centre in Gormanstown, Dublin.
"It's like a big jigsaw and we are looking at all of the information from air traffic control, recorders, radar and we are building a picture from that," Mr Whyte said.
He would not disclose if investigators had established exactly where the plane touched down.
A specialist 40ft lorry with a powerful crane has been brought in to lift the wreckage on to a low-loader for secure transport to Dublin.
