The Australian Transport Safety Bureau will begin an investigation into a serious plane crash in central western NSW which left a trainee pilot and instructor in a critical condition in hospital.
Emergency crews found the four-seater single-engine Cirrus SR-22 aircraft engulfed in flames on Aerodrome Road at Orange Airport about 7.10pm on Tuesday.
The two occupants, a man and woman, were airlifted to Royal North Shore Hospital suffering critical burns, police said.
The ATSB said the pair were conducting a training flight at the time of the accident.
A team of ATSB investigators will begin an investigation on Wednesday morning, examining the wreckage, gathering available recorded data and interviewing witnesses.
