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.
Remaining stems can then be shortened to shape. Shrubs that should be pruned this spring soon after flowering include lilac, deutzia, kerria, mockorange, weigela, forsythia, viburnum, St. johnswort and redtwig and yellowtwig dogwood. Shrubs that bloom after June 15 can be pruned in early spring. Summer and fall flowering shrubs bloom on new wood or stems that were produced in the same season as flowering. Many of these shrubs can be pruned by the scary rejuvenation method. Rejuvenation is the complete cutting of all stems down to 4 to 6 inch stubs generally done in February and March.
