Four people injured in a Northern Territory plane crash remain in hospital as investigators probe what went wrong.
A pilot and five passengers were taken to hospital in a serious condition on Friday after their single-engine aircraft hit terrain near an airstrip and landed upside down at Groote Eylandt, in the Gulf of Carpentaria.
A Royal Darwin Hospital spokeswoman said on Saturday two people had since been discharged while four were now in a stable condition.
The Australian Transport Safety Bureau previously said engine problems could be to blame and the investigation is ongoing.
Anindilyakwa Land Council, which represents the local traditional owners, confirmed four of its employees were involved in the crash.
ALC chief executive Mark Hewitt has placed a temporary ban on company travel using single-engine charter planes as a safety measure.
“The ALC has banned all charter flights using single-engine aircraft for travel for its employees and has suspended its charter contract with Katherine Aviation pending the outcomes of the Australian Transport Safety Bureau investigation,” Mr Hewitt said in a statement on Saturday.
“We are also seeking to fast-track a more substantial solution which will give the ALC much more control over risk, reliability and safety for our employees and our community.”
The council is providing support to the families of injured employees.
Groote Eylandt is the largest island in the Gulf, with a population of about 3000 people, and is part of the NT.
