Reliability analysis techniques: How they relate to aircraft certification

Classic reliability analysis techniques, namely, reliability prediction, fault tree analysis (FTA) and failure mode effect analysis (FMEA) are the framework for the aircraft certification process. These innovative technique have been utilized since the 1990s with the advent of the society of automotive engineer´s aerospace recommended practice 4761 (SAE ARP 4761). Today, SAE ARP 4761 is the defacto standard used for aircraft certification. SAE ARP 4761 draws heavily on reliability techniques with roots steeped in the military programs of the 20^th century..
