Research Project Title Preventive Maintenance Improvement Availability Generators of Aerodome Control Tower at Suvarnabhumi Airport Industrial Research Project
Abstract:
This industrial research project presented a preventive maintenance plan for the generators of
aerodome control tower at Suvarnabhumi Airport. The study aimed to increase the average time
between failure and the percentage of the overall availability of the generators. The current
maintenance system was reviewed, and it was found that maintenance was only done when the
generators broke down. In addition, there was no data collection to identify the cause of the
breakdown for the preventive maintenance purpose. This study developed a preventive maintenance
plan, starting with a data collection system of the breakdown to identify the main causes. Then
maintenance activities as well as the control and monitoring were initiated to complete the
preventive maintenance plan. The plan was implemented for 24 months and compared with the data
of the previous 12 months. The results showed that the maximal unavailability of the generators was
decreased from 79.07x10 -4 to 9.42x10 -4, or equivalent to 88 percent reduction.
