The activity on the Beech Model 385 Air Refueling Store consisted of duplication of reported deficiencies encountered on flight test, on ground test, and corrective reworks. Test results prove that the store did not function as intended during flight tests. It was found that the coupling required excessive force for engagement, and that the fuel pressure in the hose resulting from pressurization against a partially open but not fully engaged coupling stiffened the store hose excessively and to the extent that all response power was lost. The coupling manufacturer will correct the coupling deficiency and the excessive hose stiffening under the pressure was corrected by restoring the lubrication of the hose which was removed to accomplish hose marking. The store will be ready for return to flight test when a satisfactory coupling has been received and tested.
