INITIAL investigations have begun into the plane crash near Roma that killed cattle producer John Quintana and livestock agent Charlie Maher last month.
Both were killed when the single-engine Cessna T210N they were travelling in crashed on March 25.
Mr Quintana was flying his own plane to the Northern Territory to check on cattle, along with Ray White Livestock Australia chief executive officer Mr Maher.
The initial report by the Australian Transport Safety Bureau stated the plane crashed about 5.25am. A witness heard the crash and called police.
It also noted the plane's pilot, Mr Quintana, had 6000 hours of flying experience but did not hold a night visual flight rating or an instrument flight rating.
Information derived from the Geoscience Australia website indicated the beginning of daylight for aviation purposes was about 5.50am with sunrise just after 6.10am.
Available records provided no indication of any medical condition that could have affected Mr Quintana's ability to fly.
The investigation is ongoing and will include a review of the pilot's experience and records, an analysis of witness statements and a collection of meteorological information.
A final report is scheduled for release in January next year.
