The Robinson is being added to a fleet that has MD500s and OH-58s in it so those 1100 hours are not being thrust upon the one airframe. I was guess that the acquisition is to replace the OH-58s which must be very tired airframes by now and an economic option. It remains to be seen whether Polk choose to buy more when other airframes grow too old to support .... or whether they have their MD500s rebuilt into 530s.
