Abstract : In a previous program 8 similar specimens were tested, two at each of the following load sequences: (1) random load, (2) programmed load, (3) random load with ground-to -air cycles, (4) programmed load with ground-to-air cycles. The present two tests consist of ground-to-air cycles (GTAC) only. The following trends were observed: (1) the picture of fatigue critical cracks was somewhat different in the GTAC tests than in the eight previous tests, (2) the damaging effect of GTAC of the previous tests reasonably obeys the linear damage rule.
