4. 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.
