Abstract:

Although there is a connection between time in service and fatigue effects, it is not a clear-cut, straight-line type of relationship. The effect of flight time on structural integrity is greatly modified by operating conditions, pilot technique, and the quality of maintenance and inspection. Of these factors, maintenance and inspection is probably the most important. Experience shows that fatigue damage does tend to increase with time in service, but proper inspection and maintenance, which become more important as the airplane ages, will find these conditions and correct them before serious damage is created. The actual service life of the airplane is usually determined by an economic factor rather than a wearout factor.
