Analisis Kegagalan Battery P/N 2758 dengan Menggunakan Metode RCM pada Pesawat Airbus 320 di PT XYZ

Abstract

The Battery component on the Airbus 320 plays an important role in the aircraft’s electrical system, especially when the aircraft is on the ground, during the start process of the Auxiliary Power Unit (APU), and in emergency conditions. Battery P/N 2758 is categorized as a NO GO item, meaning that if it fails, the aircraft is not permitted to fly. This component is a hard time component with a specific service life limit. Based on PT XYZ data, there were 184 cases of component removal within one year, indicating a high failure frequency before the end of its service life, which increases maintenance costs and disrupts flight schedules. This study analyzes the causes of Battery P/N 2758 failures and determines maintenance strategies using the Reliability Centered Maintenance (RCM) method with Failure Mode Effect Analysis (FMEA) and Fault Tree Analysis (FTA) approaches. The FMEA results identify four failure modes: Low Voltage, Battery Weak, Battery Drop, and Low Insulation, with Low Voltage having the highest RPN value of 192. FTA identifies three main causes: human error, improper work procedures, and environmental conditions. The recommended RCM strategies include Scheduled On-Condition Task and Failure Finding Task, with preventive actions such as voltage inspection, cleanliness maintenance, and proper storage temperature. This approach effectively minimizes failures by improving procedural discipline and regular inspections.
