The upshot was that the RAAF told Army to take over helicopters and Army refused to maintain airfield defence capability which RAAF had to adopt. So now we have an Army with its own Air Force and an Air Forcer with its own Army.
The driving force behind dropping the Engineering Standard was that the alternative repairs were cheaper and faster to perform than more rigorous "repair for life" repairs. But if you save five hours to put on a crap repair which falls off in a year or two and you have to repeat it again and again, is it really cheaper? And when the repair fails and corrosion or further disbonding starts, it is certainly not cheaper. Then as the repair gets bigger and bigger, you need engineering disposition with even more cost until you have to replace the part.
But the initial repair is faster and cheaper!!
