“…3) The test may reveal several cracks which are insignificant for safety but which are important for the economic operation of the aircraft* 38 ' 39) . Harpur and Troughton (33) and also Rhomberg' 40) evaluating this argument came to the conclusion that full-scale testing is fully justified from the economic point of view. In many cases the economic argument will not allow an easy and relevant evaluation, but we should recognise that a flight-simulation test on a full-scale structure is equivalent to "flying the aircraft in the test hall" and valuable structural experience may be gained.…”

Fatigue in aircraft structures is a problem for which quantitative and generally accepted solutions are not available as yet. Even in recent years significant fatigue failures in aircraft structures have occurred. Some of these failures can be attributed to either poor design or underestimating of the fatigue environment. Unfortunately such statements are of little help since there are a confusingly large number of aspects involved. For a designer considering fatigue problems, experience, qualitative understanding and a good intuition are therefore essential.
