Paper is concerned with study of accumulation of damage under complex loadings encountered in service, rate of fatigue-crack propagation, and residual static strength; rates of crack propagation tend to increase and residual static strength tends to decrease as strength of materials increases; ground-air-ground and other negative loadings accelerate damage to certain critical sections so that fatigue life in these areas should be estimated on basis of number of flights, rather than flight miles or flight hours; regular inspection for cracks is necessary to assure safe operation of existing flight structures.
