This paper describes the System Safety Engineering Program of the AH-56A. The three most important aspects of setting up a proper program; the safety organization, control of safety effort, and the personnel requirements are discussed. An example of the failure-effects method of analysis, which is the method found most suitable for the AH-56A, is given. This example includes all of the worksheets used in conducting the analysis. Both the original design of the example (the fuel system), and the design as changed as a result of conducting the failure-effects analysis are shown. Finally, the quarterly safety reviews held between Lockheed and the Army are discussed. The procedures for conducting the meetings, personnel attending the reviews, as well as the manner in which the Army reviews and supplies their inputs into the safety program, are discussed.
