Abstract

The process of aircraft production and maintenance cannot be separated from various obstacles related to data collection and documentation. So far, at AMO PPI Curug, the recording is still in hardcopy and softcopy. The hardcopy recording uses a recording form which is monthly recapitulated while softcopy recording uses Microsoft excel which is daily recapitulated from the summary of monthly data. The problem analysis found that there are frequent occurrences of input and data collection errors in the addition of flight hours that made it inefficient in work performance and schedule inspection. The research purpose is to develop an application design for a digital-based maintenance recording system on training aircraft at the Approved Maintenance Organization. The Research and development (R&D) research method are used to develop products into the results of product effectiveness testing. The research result shows that the application has web-based specifications and it can be used on a computer device platform or Smartphone gadget. The conclusion is that the electronic-based maintenance recording application can run well and it has a very good level of satisfaction in testing.

Abstract

Penelitian ini berdasarkan kebutuhan terhadap struktur kurikulum dan pembelajaran yang tepat program Direct Approval European Aviation Safety Agency (EASA) Part 66/147 Program Studi Teknik Pesawat Udara (TPU) Politeknik Penerbangan Indonesia (PPI) Curug pada Tahun 2020. Perbedaan fundamental struktur kurikulum dan pembelajaran EASA dengan standar Badan Pengembangan Sumber Daya Manusia (BPSDM) Perhubungan untuk Prodi TPU PPI Curug diduga menyebabkan proses dan hasil pembelajaran program EASA second site tahun 2013 sampai 2018 tidak optimal, terukur dari hasil audit internal dan hasil EASA examination. Perbedaan modularisasi, tata cara pembelajaran praktik, durasi mata ajar dan durasi pembelajaran untuk capaian pembelajaran yang hampir setara dengan standar Civil Aviation Safety Regulation (CASR 147) di Prodi TPU. Implementasi kurikulum dan pembelajaran dengan memasukkan silabus EASA Part 66 dalam mata kuliah Prodi diimplementasikan dalam pembelajaran Program D III TPU Angkatan ke-12, Angkatan ke -13 dan Angkatan ke-14. Hasil examination dinilai tidak memenuhi target karena rerata hasil ujian pertama menunjukkan 81 % taruna gagal untuk mendapatkan nilai passmark. Hipotesis peneliti kegagalan tersebut disebabkan adopsi kurikulum EASA belum diimplementasikan secara tepat dalam pembelajaran konvensional Prodi dan perlu direkonstruksi ulang tepat untuk memberikan dampak pembelajaran standar EASA. Tools untuk menganalisis program tersebut menggunakan model CIPP (Stufflebeam, Daniel F, 2000 hlm.282) yang dapat diterapkan untuk evaluasi konteks dalam pembelajaran. Data diperoleh dari internal audit, hasil EASA examination, studi literatur dokumen terkait serta wawancara terhadap dosen dan taruna yang terlibat dalam program second site serta pembanding dari Politeknik PPSDMPU dengan approval AMTO 147. Data hasil evaluasi konteks diolah secara kuantitatif dan kualitatif melalui metode Mixed Method Research (Creswell dan Clark, 2000) secara concurrent triangulation untuk mendapatkan gambaran yang utuh permasalahan dan hipotesis. Temuan penelitian memperlihatkan perlunya penyesuaian terhadap program penngembangan speciality knowledge dan experience bagi pengajar, fasilitas belajar yang sudah mengalamai downgrade, komposisi teori dan praktik dalam kurikulum, kebutuhan belajar taruna, kebutuhan pasar global dan regulasi domestik, dukungan stake holder internal, kedalaman dan keluasan bahan kajian dan buku referensi. Hasil evaluasi konteks tersebut menjadi dasar hipotesis rekonstruksi struktur kurikulum baru yang sesuai dengan lingkungan pembelajaran yang mengakomodasi semua standar yang berlaku baik EASA part 66/147, CASR 147 dan standar nasional pendidikan dengan optimal.

Abstract

Pemeliharaan struktur pesawat merupakan aspek krusial dalam menjaga keselamatan dan keandalan operasional, khususnya pada komponen aft cargo door pesawat Airbus 330 yang berperan mempertahankan integritas fuselage dan tekanan kabin. Dalam praktik maintenance, kerusakan seperti dent, scratch, dan chafing sering ditemukan dan berpotensi menurunkan kekuatan struktural material Aluminium Alloy 2024-T3, sehingga diperlukan metode perbaikan yang sesuai dengan batasan kerusakan pada Structural Repair Manual (SRM). Penelitian ini bertujuan menganalisis pengaruh repair blend-out terhadap kekuatan tarik (tensile strength) struktur aft cargo door menggunakan metode kuantitatif eksperimental melalui pengujian tarik berdasarkan standar ASTM E8/E8M pada dua kondisi spesimen, yaitu tanpa repair (initial thickness) dan setelah repair blend-out sedalam 0,25 mm (kategori repair B sesuai SRM), dilanjutkan dengan uji statistik Independent Samples T-Test. Hasil pengujian menunjukkan spesimen initial thickness memiliki rata-rata Ultimate Tensile Strength (UTS) 482,72 MPa, yield strength 344,84 MPa, dan elongation 17,92%, sedangkan spesimen repair blend-out menghasilkan rata-rata UTS 440,64 MPa, yield strength 311,42 MPa, dan elongation 14,68%. Uji statistik menunjukkan perbedaan yang signifikan (p<0,05) pada seluruh parameter, dengan penurunan tensile strength sebesar 8,72%, yield strength 9,69%, dan elongation 18,08% akibat berkurangnya luas penampang efektif material. Meskipun demikian, kedalaman blend-out pada penelitian ini masih berada dalam batas allowable SRM kategori B, sehingga metode repair blend-out tetap dinyatakan valid dan efektif untuk diterapkan pada aft cargo door, dengan catatan penurunan kekuatan tarik perlu diperhitungkan dalam analisis structural safety margin sesuai prosedur airworthiness yang berlaku.

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

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.
