A senate committee has recommended a Defence report into the 2023 Taipan army helicopter crash be reviewed after claims of corruption and fabricated evidence.
The committee heard explosive claims that an independent Defence Flight Safety Bureau (DFSB) report had been corrupted by an "obvious" conflict of interest.
The senate has also recommended the Department of Defence reconsider eligibility for the Roll of Honour at the Australian War Memorial.
The senate probe into the MRH-90 crash, which claimed the lives of Captain Danniel Lyon, Lieutenant Max Nugent, Warrant Officer Class Joseph "Phil" Laycock and Corporal Alexander Naggs, began its inquiry in June.
The IGADF inquiry had heard the TopOwl 5.10 software had a tendency to give incorrect readings when pilots turned their heads.
Major Wilson said he had flagged issues with the technology with Defence before it was pushed into service, fearing someone would die if it was rolled out.
Senator David Shoebridge asked Major Wilson at the first hearing in June.
The DFSB investigation into the downing of the MRH-90 found it was unlikely the TopOwl technology contributed to the crash.
DFSB director Group Captain David Smith was questioned about the alleged conflict of interest at the senate hearing but said any perceived conflict of interest was not the subject of the report.
The senate has now released a set of recommendations following its probe, including that the Australian government independently review the DFSB report "to ensure the investigation and its findings were not improperly influenced and conclusions are sound".
