Abstract

PT XYZ is one of the air transportation companies in Indonesia that experienced delays in completing C-check maintenance based on a predetermined schedule. The TAT (Turn Around Time) indicator is used to measure the performance in completing the maintenance at PT XYZ. This research aims to determine the factors that cause maintenance delays on the B737NG aircraft and minimize TAT delays. This research uses fishbone diagrams and Pareto diagrams to find the root causes. There are three main factors that cause the delays, namely due to lack of manpower, the process of waiting for material supply, and the length of time to process the findings. In order to strengthen the analysis, this research uses the Define Measure Analyze Improve Control (DMAIC) method with the support of FMEA to develop a table for the RPN values or risk priority scale. The calculation results show that the highest RPN value is not paying attention on the ratio of work to manpower, which gives an RPN value of 216. Then a solution is recommended to reduce the RPN value to become value 168 where the aim is to reduce the TAT delay in completing the C-check maintenance of PT XYZ’s Boeing 737NG aircraft.

Abstract

An airplane is a means of air transportation used to transport passengers and goods from one place to another. Just like other transportation in general, aircraft also require maintenance. One of the aircraft maintenance activities is maintenance on the Main Wheel and Brake of the aircraft which has an important role on the aircraft. In Wheel and Brake maintenance is examined in detail with various methods, one of the methods used in Wheel and Brake maintenance is the Non-Destructive Test (NDT) method. In this case, to carry out the Non-Destructive Test inspection the company must be able to distribute Manpower needs with a good and appropriate Manhour. This study aims to optimize the allocation of manpower and time (manhour) in the implementation of Non-Destructive Test (NDT) inspections at the Wheel and Brake Shop using the Vogel Approximation Method (VAM), resulting in savings in human resources and increased efficiency in the implementation of Non-Destructive Test (NDT) inspections at the Wheel and Brake Shop. From the results of the analysis, it can be seen the distribution of manhour on various NDT component jobs and it is found that using the Vogel's approximation method (VAM) calculation results in 588.3 manhours. it is known that by using the VAM method the difference obtained is 47.7 manhours faster than the actual data which is 636 manhours with a percentage of 13.2% faster.
