Family members could start to receive answers into the cause of Tuesday's plane crash which claimed the lives of two Border men within weeks.
The Australian Transport Safety Bureau has had staff at the scene of the crash at Sutton.
The Albury-based Cessna, which was manufactured in 1977 and first registered in July 1978, is being examined by investigators.
The ATSB is undertaking a short investigation with an initial report likely within weeks and full findings due between October and December.
A spokesman for the investigator said the plane had been conducting power line inspections at a height of about 500 feet when something went wrong.
The Cessna crashed into a paddock.
"A team of transport safety investigators with experience in aircraft operations and aircraft maintenance has deployed to the accident site from the ATSB's Canberra office, and are expected to be on site for a number of days," the spokesman said.
"Once on site, investigators will examine the wreckage and map the accident site, including using a drone.
"The ATSB will also analyse available recorded data and interview witnesses and other involved parties.
"A preliminary report is expected to be released in a number of weeks, while a final report will be published at the conclusion of the investigation.
"However, should any critical safety issues be identified at any stage during the course of the investigation, the ATSB will immediately notify relevant parties so appropriate safety action can be taken."
Witnesses have spoken to investigators.
Any devices on the plane will also be examined for flight data.
