This paper describes the background work used to determine causes of Cannot Duplicate (CND) and Bench Checked, Serviceable (BCS) action. A new figure of merit, Expended Maintenance Importance Ratio (EMIR) is discussed. Techniques for eliminating CND and BCS actions through off aircraft techniques are discussed, using data from in-depth studies. Current efforts to identify on aircraft improvements in flight control systems are discussed. Development efforts discussed include: A BIT effectiveness model used to unambiguously quantify diagnostic results. Near real time diagnostic systems for use on board aircraft. Suggested on aircraft measurements required to eliminate CND and BCS diagnostic results.
