Fatigue crack propagation is studied under random flight simulation loading and two types of programmed flight sequences. Tests are carried out on 2024-T3 Alclad specimens. Fractographic observations are made to determine the severity of individual flight types. Seven different flight types from a total of ten can be distinguished on the fatigue failure surfaces. Their severity is determined on the basis of crack extension.
