Abstract

Safety and operational efficiency are fundamental pillars of the aviation industry, where the reliability of each aircraft component plays a vital role. One crucial component of the Airbus A330 fuel system is the Twin Motor Actuator (FRH010041), which controls the crossfeed valve between wings. Failure of this component may disrupt fuel distribution and significantly impact flight safety. This study aims to analyze the root causes of 40 repetitive failure cases recorded at PT GMF AeroAsia from 2020 to 2024. The urgency is reinforced by its classification under the Minimum Equipment List (MEL) category Repair Interval B, requiring repair within three calendar days. The research employs a qualitative Root Cause Analysis (RCA) approach, using Pareto Diagram, in-depth technician interviews, Fishbone Diagram mapping, and the 5 Why and Focus Group Discussion (FGD) techniques. Results indicate that connector corrosion is the dominant failure mode (50%), driven by the absence of corrosion inspection procedures in the Maintenance Planning Data (MPD), poor compliance with the Aircraft Maintenance Manual (AMM), and high humidity exposure in open hangars. The failure of the Twin Motor Actuator reflects systemic weaknesses in maintenance procedures, work culture, and operational environment, highlighting the need for strategic corrective actions to enhance component reliability and flight safety.

Abstract

This study analyzes the recurrent failure of the Cabin Rate of Climb Indicator (P/N WL501RC1) on Boeing 737-800 aircraft maintained by PT. GMF AeroAsia Tbk. The research aims to identify the main causes of unscheduled removals and propose improvement strategies to enhance maintenance reliability. The study employs a qualitative method using the Root Cause Analysis (RCA) approach, supported by Pareto and Fishbone diagrams. Data were obtained through interviews, field observations, and technical documentation, including Component Removal Reports and Out-of-Tolerance Notifications. The results show that “Housing Leak” is the dominant failure mode, accounting for 46% of total cases between 2019 and 2024. The root causes were linked to human error in O-ring installation, outdated work procedures, reduced test bench accuracy, substandard repaired materials, and environmental exposure affecting component elasticity. Corrective and preventive actions include technical training, updated maintenance documentation, and stricter quality control on materials and testing equipment. These findings provide a practical basis for improving MRO performance and aircraft operational reliability.

Abstract

Flight safety is a critical component of the aviation industry, with human performance being a primary factor in maintenance-related incidents. This study investigates the impact of human factors specifically the "Dirty Dozen" on safety culture at PT. Mulya Sejahtera Technology. Using a quantitative method, data were gathered from 79 technicians through an online questionnaire. Descriptive analysis indicates that while human factors are rated as "good" (73.1%), the safety culture remains at a "moderate" level (56.2%). Simple linear regression analysis confirms a significant influence of human factors on safety culture (Sig. 0.006 < 0.05), with an R-Square value of 8.1%. These findings suggest that addressing specific human factor issues, such as resource availability and technician awareness, is essential for strengthening the organizational safety culture.
