My understanding is that Boeing has the contract to supply instructors, day SAR and loadmaster training. The last two being subcontracted to Australian Helicopters.
The instructor side has been done, I believe, by re-employing existing civvy instructors and have advertised for some additional ones but must have previous QHI experience within past 2 years.
AH has recently (about 6 weeks ago or so) advertised for B412 pilots to fulfill their comittment to Boeing. Not sure if they have their pilots (2 off) yet or not?? Apparently the Army will do the night SAR coverage because of their requirement to fly NVG at night. So the SAR coverage by AH is purely day....so I believe?
