This check is referred to as an operational flight check in the latest revision of the GMM and GOM. A tail rotor has been changed on a BO-105. After the assembly is installed there will be functional checks involving rigging, flapping, and balance. functional check evaluates only a single system within the entire aircraft. This is not to imply that all systems in the aircraft must have a functional check to complete an operational check on the aircraft.
Cut back shrubs grown primarily for their foliage, such as barberry and burning bush, almost anytime except in late autumn. New growth that starts after late-season pruning won't harden off properly before winter. If you want to do major pruning, it's best to cut the shrub back when it is dormant in winter.
If you want to research the particular shrub that you grow before deciding on the best pruning time for it, find it in my Plants Database. When to Prune Evergreen Shrubs In general, prune needle-bearing evergreen shrubs in early spring, toward the end of dormancy and prior to emergence of new growth. Pruning the evergreens at this time allows plenty of time for new growth to emerge, as well as plenty of time for these new shoots to harden off before the following winter.
