Abstract
An identified component of Airbus A-330 aircraft which should be maintained properly is the normal braking system. The objectives of this study are to: (1) identify the critical component of the normal braking system; and (2) determine the optimal replacement time interval of replacement of the normal braking system component. This study is conducted in Garuda Maintenance Facility Aero Asia company. Primary data in this study are the components replacement data of normal braking system in period January 2015 - January 2017. The life distribution such as Mean Time to Failure (MTTF), reliability, probability density function, cumulative distribution function, and failure rate are obtained by the Weibull++ software. Results show that the critical component of the normal braking system is the brake unit assembly. Meanwhile, the life distribution analysis show that the reliability of importance value of the normal breaking system IR is 74.07 percent which occurs at MMTF and system reliability are 4365.5 hours and 55.58 percent, respectively. These values indicate that optimal replacement time interval of the Brake Unit Assembly is 5599.7 hours.

Summary
Aeroplane safety in flight is under the influence of many factors. One of these factors is braking safety while the aircraft is landed. In order to reduce failure of the braking system, monitoring and checking of the system are required. These activities involve analysis of the pilot report, delay report and maintenance report. Pilot report is the data from the pilot while an error occurs in flight such as taxing, take off, flight, and landing. Delay report is the incident flight report which causes airplane delay. These data are obtained from the real flight conditions
