description This paper examines two individual aircraft tracking methods for tracking crack growth in fighter aircraft utilizing counting accelerometer data. Individual aircraft tracking programs were developed for the F-4 and A-7D aircraft in conjunction with damage tolerance assessment programs conducted for these aircraft. Both the F-4 and A-7D tracking methods were based on existing counting accelerometer data acquisition systems. The F-4 tracking method utilizes an equivalent S-N curve system to calculate a damage index at a monitoring location. The A-7D tracking method utilizes regression analysis to calculate equivalent baseline hours expended at a monitoring location. Both methods then relate damage at the monitoring location to damage at other critical structural locations.
