Abstract

Masalah kebocoran bahan bakar pada mesin pesawat merupakan aspek krusial dalam menjaga keselamatan penerbangan dan efisiensi operasional. Penelitian ini bertujuan untuk menganalisis penyebab dan dampak kebocoran bahan bakar yang terjadi secara berulang, serta memberikan solusi untuk mengurangi frekuensi dan dampak kebocoran tersebut. Metodologi penelitian yang digunakan mencakup pengumpulan data dari insiden sebelumnya, termasuk data pilot report Maskapai ABC tahun 2018-2020, menganalisis penyebab akar masalah, serta simulasi kondisi operasi. Penelitian ini bertujuan untuk mengidentifikasi pola dan faktor yang berkontribusi terhadap masalah kebocoran. Dengan ini, keselamatan penerbangan dapat ditingkatkan dan kebocoran bahan bakar dapat diminimalisirkan. Dari hasil penelitian, ditemukan enam registrasi pesawat yang mengalami kebocoran bahan bakar berulang, salah satunya mengalami kebocoran bahan bakar berulang sebanyak tiga kali. Kebocoran tersebut disebabkan oleh berbagai faktor, yaitu keausan material, kesalahan dalam proses pemasangan, dan tidak adanya tindakan permanen. Adapun langkah-langkah yang dapat meminimalisir terjadinya kebocoran bahan bakar berulang seperti, melakukan inspeksi lebih sering pada komponen sistem bahan bakar, dan melakukan penggantian komponen berdasarkan rekomendasi pabrikan atau interval waktu yang sesuai meskipun komponen tidak menunjukkan tanda-tanda kerusakan.   The issue of fuel leaks in aircraft engines is a critical aspect of ensuring flight safety and operational efficiency. This thesis aims to analyze the causes and impacts of recurring fuel leaks, as well as provide solutions to reduce the frequency and impact of these leaks. The research methodology includes data collection from previous incidents, including pilot reports from ABC Airlines between 2018 and 2020, analyzing the root causes of the issues, and simulating operational conditions. It is hoped that this study will identify patterns and factors contributing to the fuel leak problems. In turn, this will contribute to improving flight safety and minimizing fuel leaks. The research findings identified six aircraft registrations that experienced recurring fuel leaks, one of which had repeated fuel leaks three times. These leaks were caused by various factors, including material wear, installation errors, and the lack of permanent corrective actions. Steps to minimize recurring fuel leaks include more frequent inspections of the fuel system components and replacing components according to manufacturer recommendations or suitable time intervals, even if the components show no signs of damage.

Abstract

The lack of adequate physics laboratory facilities for conducting flight physics practicums in Aviation Vocational High Schools has been a significant obstacle in the learning process. Due to these limitations, students' understanding of the physics concepts underlying aviation principles has been suboptimal. To address this issue, community service activities have focused on enhancing the capacity of teachers at Gutama Aviation Vocational High School to design and implement physics practicums. Through the creation and utilization of Integrated Instrument Kits (KIT) for flight physics, it is hoped that teachers can provide more concrete and engaging learning experiences for students. With the successful development of 5 KITs, teachers now have the skills to design a variety of practical activities that meet the needs of their students. Additionally, the provided mentorship has equipped teachers with a deep understanding of physics concepts relevant to the aviation industry. It is hoped that the success of this activity can improve the quality of physics education at Gutama Aviation Vocational High School, encourage teachers to be more innovative in developing additional KITs, and prepare graduates who are more competent in the field of aviation.

Abstract

The lifting of the Restriction of Community Activities (PPKM) in January 2023 was the beginning of the aviation industry in Indonesia starting to rise marked by the emergence of new Maintenance Repair and Operations (MRO). Limited hangar space at MRO is a challenge in scheduling aircraft maintenance, setting the order of task cards that have been submitted by the airline and must be done in the maintenance project will be an illustration of how long this project will be done. MP item number 7122410504 contains Detailed Inspection of Aft Engine Mount Fail-Safe link is a maintenance job that can be done after the removal of Engine. The engine removal and installation process often takes more time and effort, potentially causing delays in the overall maintenance time. The purpose of this research is to make efficiency in the removal and installation process of the RR Trent 700 engine using the critical path method. The critical path method in analysing the stages of work in the maintenance process aims to identify and optimise resource allocation, so that maintenance time can be minimised and overall efficiency can be improved. The results showed that the application of the critical path method in the stages of engine removal and installation work resulted in a time efficiency of about 1,655 Hours so that the delay in work on the critical path became the main factor affecting the total duration of the engine removal and installation process.

Abstract

Maintenance management is a series of activities that include planning, organizing, program implementation, and control methods for maintenance activities. This study aims to determine whether maintenance management practices can be implemented effectively through a hybrid training method (virtual and offline) that utilizes a maintenance management laboratory. The research stages include understanding the data that must be inputted by technical records, how to read and fill out maintenance logs, and designing virtual tutorials which are then tested on aviation engineering students. In using the virtual tutorial, students input data, calculate aircraft life utilization based on Time Since New (TSN) or Cycle Since New (CSN), and calculate the life of aircraft components with the same parameters. Based on the results of testing the AFML tutorial on 10 aviation engineering students, it was found that 96% of them were able to answer the evaluation questions correctly, with 8 students answering perfectly and 2 students reaching 80% success rate. These results show that the virtual tutorial developed is quite effective and useful in improving students' understanding of maintenance management, especially in the use and analysis of AFML data.

Abstract

Spoiler is one of the components that has an important role in an airplane. This component serves to slow down the speed of an aircraft both in the air and on the ground. However, due to its classification as part of secondary flight control, its understanding is often limited to the general public as a braking device on an aircraft without paying attention to the complexity of its functions and mechanisms. Therefore, the design of this spoiler simulation is expected to help in understanding the work simulation of a spoiler on an aircraft. This tool is designed with a simple working system using a syringe and hose as a simple depiction of the hydraulic system performance on the aircraft, which is also equipped with a series of electrical systems consisting of arduino, servo and microswitch as a support system for this tool so that it can describe the difference in performance between flight spoiler (speed brake) and ground spoiler. The wing structure of this tool is made of thermoplastic material (PLA) and mica plastic, so that it can make it easier to see how this tool can work. This tool is also equipped with a lever that is duplicated as the original according to the aircraft. Based on the design and assembly that has been done, this tool is proven to work successfully in accordance with its respective functions.

Abstract

Aerodynamic principles are crucial for improving both efficiency and safety in commercial aircraft operations. This study compares three gliding strategies: (1) iterative calculation at a fixed 3° glide angle, (2) analysis of actual flight data from FlightRadar24, and (3) aerodynamic optimization using the drag polar method. The iterative approach produced relatively low descent rates 4.6–5.5 m/s and the longest glide times 1,100–1,323 s, offering safety benefits by enabling aircraft to reach more distant landing sites during emergencies. Actual flight data showed wider variations in descent rates 4.8–17.88 m/s and glide times 340–1,270 s due to operational requirements and ATC instructions. In contrast, aerodynamic optimization identified an ideal glide angle of 3.1°–4.1°, with higher descent rates 10.56–16.65 m/s but shorter glide times 366–577 s, representing the most efficient aerodynamic condition at maximum lift-to-drag ratio. Comparative analysis revealed that optimization median 512 s and actual data median 590 s yield greater aerodynamic efficiency, while the 3° fixed-angle approach median 1,186 s enhances safety margins. These results emphasize that glide strategy selection must balance efficiency and safety, integrating aerodynamic analysis with real operational data to support decision-making in commercial aviation

Abstract

Airplanes is transportation that need a high level of safety and comfort. Therefore, the aircraft's parts must be in excellent shape and able to fly. This study aims to assess the reliability of battery maintenance on A330-900 aircraft using the reliability mapping method, as well as to assess the efficiency of doing so in order to compare the reliability mapping method's implementation to maintenance schedules for the batteries on these aircraft. The stages of this study started with gathering maintenance information for the A330-900, then went on to classify the different types of maintenance and create reliability mapping tables. Additionally, a comparison between the implementation and maintenance schedule for the A330-900 aircraft battery was made in order to analyze the reliability of battery maintenance on the A330-900 aircraft and to determine the effectiveness of using the reliability mapping method. After that, carry out reliability mapping optimization computations till conclusions about the research's findings are reached. Reliability mapping makes it evident where and when unforeseen maintenance takes place. The fact that just 3 unscheduled maintenance visits totaling 5.5% of the total maintenance were made out of the 54 replacements shows how dependable the battery maintenance on the A330-900 is. The execution of battery maintenance is reportedly wrong, with numbers based on estimations made according to calendar time being 77% early, 19% late, and 4% accurate

Abstract

In aircraft operations, to determine the amount of fuel consumption on the aircraft, it is necessary to know the time used for holding. Holding time is influenced by the number of aircraft using runway facilities and can be calculated using queuing theory. This study aims to determine the calculation of fuel consumption on aircraft when holding at Halim Perdanakusuma International Airport using queuing theory. Data for queue calculation is based on observations on flightradar24. Fuel consumption is estimated using aircraft maximum landing weight data, turning flight performance theory and aircraft manuals. From the results of the calculation, it was found that it took 6 minutes for the aircraft to queue during holding, from this time the fuel consumption calculation was carried out on the holding pattern and obtained the most fuel consumption results on the KOMIT holding pattern, which was 241,8 kg based on queuing theory and 554,8 kg based on actual data calculations. The difference in fuel consumption results is far due to the difference in time used. The time obtained based on queuing theory is 6 minutes and is equal for each holding pattern, while the time obtained based on actual data varies from one aircraft to another. For turning flight performance capabilities, the A320 aircraft can maneuver 180º within 1 minute with the largest radius of 9.204 m in 61 seconds or 1 minute 1 second on the IMU holding pattern and a radius of 2.327 m in 60,6 seconds or 1 minute 6 seconds on the COMMIT holding pattern.
