A probabilistic fatigue damage tracking method for airframe structure with an inspection criterion of Single Flight Probability ofFailure (SFPOF) exceeding 10-7 was compared to the conventional method for fatigue tracking. Two retired fighter aircraft wingswere experimentally loaded with different load histories. Fatigue at 14 locations in the outer portion of each wing were trackedwith both methods. It was thought that probabilistic tracking would results in fewer inspections because it was believed thatSFPOF at inspections with conventional tracking was significantly less than 10-7. Probabilistic fatigue tracking resulted in thesame or greater number of inspections as conventional tracking. SFPOF at the time of inspection with conventional tracking wasfrequently greater than 10-7. Thus, the greater number of inspections with probabilistic fatigue tracking.
