RIP crews and all condolences to their families, colleagues, mates...
Hope they find closure
Aside from 6th Regt, 5th also operates the MRH-90, (apart from CH-47F and pair of Toll AW139 ) and from what I have read at this juncture the 40 something Taipans grounded as matter of course. Also w.r.t FMS sale of UH-60M, the first deliveres should commence later this year to the AAAC.
All the best.
