Schedule maintenance task interval is a key index representing the reliability and economy of aircraft, and the accumulation of maintenance and fault data after aircraft service provides the basis for the adjustment of maintenance task interval. The method for data sampling size is determined by analyzing the optimization process of aircraft maintenance task interval. The failure trend analysis method based on data fitting is given to judge the necessity of interval optimization method. The hypothesis test criteria of maintenance interval optimization is defined. The proposed optimization method is verified with instance. The results show that the method can judge the feasibility of new maintenance task interval, and guide the update of maintenance review board report (MRBR).
