Latest: No distress signal was sent from the aircraft which crashed in Co Kildare yesterday evening.
The aircraft has been removed from the scene after an initial investigation by the Air Accident Investigation Unit.
Two men, one aged 70 and the other in his 50s, were killed when their light aircraft crashed in Belan near Athy.
The wreckage was located by the Rescue 116 helicopter at around half four this morning, three hours after the alarm was raised.
The Air Accident Investigation Unit is currently carrying out an initial examination of the aircraft at the scene.
Lead Investigator Howard Hughes says no communication was made by the pilot.
"Indications are there was no communication from the aircraft nor would the pilot have been obliged to have done so," said Mr Hughes.
"Kilrush Airfield is located in air space where they do not have to make radio contact with any of the major air traffic control units around Ireland.
"So our understanding at this stage is that there was no communication."
Update 1.30pm: The chief inspector of the Air Accident Investigation Unit, Jurgen White is hoping to have a preliminary report within 30 days into the fatal air accident which occurred in Kildare yesterday evening.
He told RTE radio’s News at One that at 3am this morning he received a call from an Garda Síochána that an aircraft had not returned to its base in Kilrush airfield in Co. Kildare.
An emergency response was immediately initiated involving numerous agencies including the gardaí, rescue helicopter R116 and the aviation authority which played back radar tapes to determine the last known position of the aircraft.
Once that position was identified it led gardaí to discover the downed craft in Belan, Moone, Co. Kildare with the two fatally injured men.
Two inspectors of the Air Accident Investigation Unit are at present on site recording all the information from the aircraft and conducting a full investigation of the site, said Mr White.
It is hoped that the wreckage will be removed today and transported to Gormanstown, Co. Meath, for a detailed examination.
The aircraft, which was registered in the UK, was based in Kilrush which is not an unusual situation according to Mr White.
The aircraft was on a training flight when the accident occurred, he said. It was only when families of the two men and the owner of the aircraft became concerned that the alert was activated.
He said he will keep an open mind as to the cause of the accident through the entire “long and detailed” process which will be “meticulous”.
“I hope to have a preliminary report within 30 days.”
