Flight simulation fatigue crack propagation tests on 2024-T3 and 7475-T761 aluminum alloy sheet were carried out using a gust spectrum representative of the load history of an under wing skin in a transport aircraft. The investigation included tests at several design stress levels and in environments of laboratory air and air plus water spray. The results are discussed with respect to the choice of structural concepts using 7475 alloy and evaluation of the fatigue properties of such concepts.
