Investigators have returned to the site of a fatal helicopter crash at Hobart Airport to look for evidence but say it's too early to tell what caused the aircraft to nosedive into the tarmac.
Roger Paul Corbin, 57, died when his Rotorlift helicopter plunged from about 200m above ground at Hobart Airport, just before 5.30pm on Tuesday.
Two investigators combed the crash site on Thursday for "ground scars and other evidence left behind by the impact" and will examine CCTV taken from the airport.
A 33-year-old trainee pilot survived the crash and was released from Hobart Hospital on Thursday confirmed.
He is yet to be interviewed.
The investigation is still in its early stages and an Australian Transport Safety Bureau spokesman said there won't be any "analysis or any causal factors" of the accident at this stage.
ATSB transport safety investigator David Grambauer said the accident occurred as the helicopter was coming into the airport and the pilots were conducting "training-type manoeuvres".
Mr Grambauer said it's not yet known who was in control of the helicopter when it crashed.
The helicopter wreck has been taken to a secure facility where it will be examined by an engineer, which should take a few days, he said.
Investigators will also examine the aircraft's onboard GPS and data logs and are working to get any voice recordings between the pilots and the control tower before impact.
Mr Corbin, from suburban Otago Bay, was the managing director of Rotorlift and his website said he had more than 14,000 flight hours in fixed-wing aircraft and helicopters.
Rotorlift operates the Tasmania Police rescue helicopter, helps with emergency service activities and also conducts tours and flight training.
Police it will continue to use Rotorlift for its emergency rescues, with a future agreement already in place.
"They will continue as normal, there is no impact on the emergency response to the community," Tasmania Police Inspector Natasha Freeman said.
"It is definitely a loss but there are plans in place for business continuity."
A preliminary ATSB report will be released in about a month and the final report could take up to a year to complete.
