Collective lowering 412
It might be worth mentioning that the collective should not be raised more than one to two inches of end-travel after shutdown as this defeats the object of the exercise. Many folks haul up on it like they are exhausting the hydraulic pressure in an older beast, whereas in reality this ends up loading up the flex-beam the other way and leaving the component in a 'loaded' and stressed condition after shut-down. MIL pilots seems to be addicted to this 6-inch 'pull'!
