A Senate Committee has raised serious concerns about the competency of the bodies overseeing Australia's aviation industry.
The committee has investigated the official reviews into a Pel-Air plane ditching into the ocean off Norfolk Island in 2009.
The service had been flying a patient from Samoa to Melbourne for treatment on behalf of CareFlight.
All six people on board survived but only the pilot, Dominic James, escaped without injury.
The committee has found the Civil Aviation Safety body withheld critical documents from the Australian Transport Safety Bureau and that many in the industry are reticent to speak out because of a fear of retribution, especially from CASA.
Independent Senator Nick Xenophon says of particular concern was the evidence of the head of the ATSB, Martin Dolan.
"In respect of his credibility as a witness," Senator Xenophon said.
He says the report highlights serious concerns about the oversight of the industry.
"My confidence in our aviation safety regulators and accident investigation body CASA, the Civil Aviation Safety body and the ATSB have been shaken to the core," he said.
Karen Casey was injured in the crash and says the report must be acted on.
"The truth has finally been revealed," she said.
The report has been referred to the Director of Public Prosecutions.
