The behavior of short and long fatigue cracks in the widely used damage tolerant aluminum alloy 2024-T3 was compared using flight simulation loading representatives for the Fokker 100 wing/fuselage structure. The results showed that the apparently anomalous behavior of short cracks is not significant for durability analysis of the current wing/fuselage structure. Also the data provide a reference for evaluating new, candidate materials for durable wing/fuselage structures in transport aircraft.
