PNEUMATIC TEMPERATURE SENSOR FAILURE ANALYSIS P/N 767C0000-01 ON AN AIRBUS 330-300 AIRCRAFT AT PT GMF AEROASIA

Abstrak

This study aims to analyze the causes of sensor failure at PT GMF AeroAsia Tbk. The methodology used was observation, interviews, and document analysis. Modern aircraft rely heavily on reliable support systems, including pneumatic systems for regulating cabin temperature and safety. On an Airbus A330-300, a problem with the pneumatic temperature sensor was found, with corrosion on the sensor rod resulting in inaccurate temperature readings that could impact flight safety. This study aimed to analyze the causes of sensor failure at PT GMF AeroAsia Tbk. The methodology used was observation, interviews, and document analysis. Data were analyzed using Pareto charts and Fault Tree Analysis to identify the root cause. The results indicated that corrosion was the primary cause, exacerbated by environmental factors, weak inspection procedures, and a lack of technician understanding. In conclusion, the sensor failure was caused by a combination of technical, procedural, and human factors. This research helps develop better aircraft maintenance strategies to improve safety.
