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.
