The ATA 29 hydraulic system on the Airbus A330 is a critical subsystem that supports flight controls, landing gear, wheel brakes, and thrust reversers. Hydraulic leakage in components such as flexible hoses, actuators, and the enginedriven pump (EDP) can lead to unscheduled maintenance, delays/AOG, and increased maintenance costs. This study aims to optimize the determination of A330 hydraulic component life based on the MSG-3 framework and reliability data to produce more precise replacement intervals without exceeding airworthiness limits specified in the AMP/ALS/CMM. Data were collected retrospectively from installation–removal histories (FH/FC/date) and classified as failure or censored. Reliability analysis was performed using a Weibull model to estimate the β–η parameters, MTTF/MTBUR, and RUL. The results indicate that the analyzed components have β>1 (wear-out), suggesting that the most effective control strategy is scheduled replacement (HT) or a combination with condition monitoring (OC/CM).
