A 12-year-old girl has been killed in a plane crash in northern NSW.
The pilot, a 52-year-old man, escaped from the wreckage with minor injuries.
Police said he and the girl's father, also a passenger, pulled her from the plane and gave her first aid but she did not survive.
The father, 38, is in a serious condition after being flown to Lismore Base Hospital.
Police believe the three had set out on a joy flight from Murwillumbah when the aircraft hit power lines and crashed into the Clarence River, south-west of Casino.
The pilot alerted authorities from a neighbouring property.
The four-seater aircraft remains upside-down in the Clarence River and is being examined by forensic officers.
An investigation into the cause of the crash will be undertaken by the Australian Transportation Safety Bureau.
