The authors investigated the breaking of tuna long line, for the purpose of improving reliability. The results were analysed by means of reliability engineering methodology as follows: 1 Breaking rate curve is divided into three failure periods as initial, random, and wear-out. 2 Regression lines of cumulative breaking probability on Weibull's paper made the characteristic of breaking periods distinct as being initial, random, wear-out, and progressed wear-out. 3 Breaking modes were clarified and the frequency of each mode and curves for occurence of each breaking with time were obtained.
