Abstract : The patent relates to an improved system for determining fatigue in aircraft structure. More particularly, the system provides a means for using an accelerometer system to reliably record the number of times an aircraft has experienced load factor levels above predetermined magnitudes. This enables aircraft structure to be retired in terms of fatigue experienced by the structure rather than the number of years it has been in service.
