Abstract


Engine bleed valve or pressure regulated valve is one of the components in the engine bleed system which is located on the aircraft engine. This component is based on data removal of the pressure regulated valve component from PT. XYZ. Research using the fishbone diagram method and Why analysis is used to find the causes of frequent damage to PRV components. Then the Weibull distribution method is used to obtain the failure rate and reliability level of PRV components and determines the MTTF (Mean Time to Failure) value used to determine the schedule effective treatment. After evaluating the reliability using the Weibull method, the MTTF value of the pressure regulated valve was 9161.438 FH, the most common cause of PRV unshedule removal was not closed PRV which was caused by damage to several components such as butterfly valve corrosion, carbon actuator, spring, body actuator, piston, and piston guides.
