Abstract

The engine nacelle, particularly the inlet section, plays a crucial role in propulsion performance as it affects the pressure and airflow velocity entering the fan and compressor. This study compares the aerodynamic performance of two inlet geometries: the flattened lip design of the Boeing 737-800NG and the circular lip design of the Airbus A320. A Computational Fluid Dynamics (CFD) simulation was conducted using ANSYS Fluent, with three-dimensional models developed in SolidWorks based on official geometrical data from Boeing and Airbus. The analyzed parameters included average pressure, airflow velocity, P/V ratio, drag force, and drag Coefficient under two operating conditions—cruise (Mach 0.7) and climb (Mach 0.2). The results show that the Boeing inlet produced lower drag forces, 824.43 N during cruise and 234.29 N during climb, compared to Airbus with 911.94 N and 249.56 N, respectively. The flattened lip design demonstrated better flow diffusion efficiency and reduced drag by up to 9.59%. In conclusion, inlet geometry significantly influences aerodynamic efficiency. Optimizing inlet contour can enhance aircraft performance without major structural modifications, offering potential improvements for future narrow-body aircraft design.

Abstract

This study aims to analyze failures in the Fan Extract component P/N CE1909AA1 installed on Airbus A330 aircraft at PT. GMF AeroAsia Tbk. The Fan Extract is a vital part of the avionics ventilation system, preventing overheating of electronic equipment. Engineering data from 2019 to 2024 recorded 66 unscheduled removals, indicating recurring issues requiring further investigation. Pareto analysis shows the main cause of failure is Bearing Rough (47%). Using the Fishbone Diagram with the 5M, root causes of Bearing Rough were identified as non-compliance with procedures, incorrect greasing, lack of cleaning procedures in job cards, uncalibrated tools, low bearing material quality due to OEM supply limitations, and improper aircraft storage conditions causing lubricant contamination. Corrective actions recommended include revising maintenance procedures, calibrating tools, retraining personnel, and improving storage policies. Preventive actions involve condition-based maintenance scheduling and procuring OEM-standard lubricants and tools

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

Aircraft maintenance is an essential aspect of aviation aimed at ensuring airworthiness and keeping components in optimal condition to minimize accidents. The landing gear system supports the aircraft during ground operations, takeoff, and landing, with the Alternate Brake Servo Valve serving as a vital component that regulates hydraulic pressure in the brake system. The failure of Alternate Brake Servo Valve P/N C20374000-2 on Airbus A330 aircraft at PT GMF AeroAsia Tbk has resulted in 57 unscheduled removals between 2020–2024. This study aims to analyze the factors causing these failures, identify the root causes, and provide improvement recommendations. The methods used are Failure Mode and Effect Analysis (FMEA) to identify failure modes and calculate the Risk Priority Number (RPN), and Fault Tree Analysis (FTA) to determine root causes. The analysis shows that Leak From Connection is the dominant failure mode with the highest RPN value (210). The FTA results indicate that the main causes include the absence of specific maintenance procedures, uneven standard practices training, lack of reinspection by Inspectors, non-compliance with manuals, and inaccurate tools used. Based on these findings, several corrective actions are proposed, including developing specific inspection procedures, providing comprehensive standard practices training, implementing a double-check system, emphasizing adherence to the Aircraft Maintenance Manual (AMM), and conducting periodic tool calibration.

Abstract

This study aims to improve safety and efficiency in aircraft landing gear maintenance at the Aviation Facilities Calibration Center (BBKFP). BBKFP currently lacks a landing gear stand, which increases the risk of workplace accidents and component damage during the removal, inspection, and installation processes. This research designs a landing gear stand for the King Air B350i aircraft using the VDI 2221 method, which consists of four stages: clarification of task, conceptual design, embodiment design, and detailed design. The design process was based on field observations and discussions with BBKFP personnel to determine user requirements. The tool was designed to support a load of up to 157.5 kg (safety factor 1.5), be operable by one person, have a vertical lifting mechanism, and use strong yet easily obtainable materials. The selected design features a “U”-shaped cross-section with a 2-ton hydraulic jack lifting system and pin-lock safety mechanism. The main material, SS400 steel, has a yield strength of 245 MPa. Structural analysis showed that all stresses were below the allowable limit of 61.25 MPa, with a maximum stress of 3.32 MPa. The stand is equipped with four caster wheels (350 kg capacity each) and a base frame of 1000 × 1000 × 40 mm. Functional testing confirmed the tool’s safety, stability, efficiency, and suitability for BBKFP’s operational needs.

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.

Abstract

The MRO (Maintenance, Repair, and Overhaul) industry in Indonesia still faces challenges in efficiency, productivity, and global competitiveness, especially against international companies with more advanced technology. PT XYZ, as one of the largest MROs, continues to innovate and optimize aircraft maintenance processes to reduce manhours deviation and achieve Turn Around Time (TAT) targets in line with customer commitments. Uncontrolled increases in manhours lead to higher manhours cost and lower profitability. Form Analysis Profitability Maintenance (FAPM) is used to plan maintenance project profits, where manhours cost is the largest fixed cost. Of 36 C-Check Airbus A330 maintenances conducted between 2022–2024, only nine achieved the FAPM target. This study applies Value Stream Mapping (VSM) to analyze process flow and identify non value added activities. The results show the largest deviation occurred during the inspection phase, particularly in request for material (347.4 manhours) and request for tools and equipment (295.025 manhours), categorized as waste of waiting. Through Root Cause Analysis (RCA) and the 5 Why method, the main causes were data input errors, limited safety stock, suboptimal warehouse layout, and few vendors. Solutions using the 5W+1H approach are expected to reduce deviations, lower costs, and enhance company profitability.
