An investigation's underway into what caused a plane to crash near Renmark Airport in South Australia's Riverland region.
The Rossair charter training flight took off around 4pm yesterday and struck trouble shortly after, activating an emergency beacon at about 4.30.
Police came across the wreckage 4 kilometres from the Renmark Aerodrome at about 7pm last night.
Three men were on board the twin-engined Cessna Conquest 2 - Chief Pilot Martin Scott, Re-Training Pilot Paul Dawe and CASA Officer Stephen Guerin.

Investigators will probe whether the crew were carrying out exercises during the takeoff which may have included an engine failure simulation.
Such exercises aren't used on larger planes because they're considered too dangerous.
Rossair has grounded its entire fleet while the investigation takes place.
The crash is South Australia's worst aviation accident since the Whyalla Airlines disaster killed 8 people in 2000.
