Take a Bex and have a good lie down Dick. It really is quite amazing what can be found through a simple search on Google:
B300 King Air Fleet returns to service : Department of Defence
RAAF King Airs return to the air | Australian Aviation
The aircraft were grounded on 30 June and recommenced flying on 4 August, so they were grounded for about 5 weeks, not 'over three months' as was claimed earlier.
