Abstract : The G-222 is a transport aircraft designed about 20 years ago; from the fatigue point of view the design is of the conventional 'Safe Life kind, verified by means of a full scale test. The aircraft was equipped with a counting accelerometer, whose recordings have been used, together with the pilot-compiled forms, for the evaluation of life consumption. In recent years, following the Damage Tolerance evaluation of the structure, a different approach has been developed for fatigue damage monitoring: the same input data are used for the prediction of crack growth. The main drawback of this approach is the lack of information about the sequence of load application, so that only non-interactive models can be properly used.
