MRH 90s still grounded

The ADF’s current fleet of MRH 90 helicopters remains grounded nearly three months after an aircraft experienced a catastrophic engine failure near RAAF Edinburgh on April 20.

“MRH 90 flying operations are suspended whilst the investigation into the cause of the engine failure continues,” a Defence spokesperson told Australian Aviation on July 8. “An Aircraft Incident Investigation Team has been investigating the incident with support provided by the DSTO, the engine manufacturer (Rolls-Royce Turbomeca) and the aircraft manufacturers (NHI and Australian Aerospace). This is a complex investigation, and the precise cause of the failure has not yet been identified. Detailed investigation and analysis are continuing.”
