Abstract : The unreliability of some current cargo handling systems has resulted in the loss of expensive military equipment. Additionally, the unavailability of aircraft and the many maintenance man-hours on cargo handling systems have caused increased costs and mission aborts. The basic reason for this has been a lack of appreciation, by both the Army and the helicopter manufacturer, for the rigors of cargo helicopter operation. Southeast Asia experience has shown that rough handling and the combined effects of extreme environmental conditions and operational cycles are the leading causes of cargo handling system failures. The purpose of the report is to present cargo handling system qualification test methods which better represent actual field use and to systematize methods for demonstrating stated reliability requirements for these devices.
