Abstract

Kecelakaan karena tabrak burung sering terjadi pada operasi penerbangan serta pada saat musim migrasinya burung-burung, hal ini dapat menyebabkan kegagalan struktur serta mengancam keselamatan penerbangan. Efek yang terjadi pada komponen struktur pesawat yang terkena tumbukan tabrak burung ini umumnya berupa deformasi penyok (Dent) atau berlubangnya lapisan kulit pesawat serta struktur lainnya. Penelitian ini membahas tabrak burung pada Leading Edge dengan metode SPH (smooth particle hydrodinamics) berbasis metode komputasi numeric elemen hingga (finite element method). Struktur Leading Edge diasumsikan hanya terdiri dari skin dengan memvariasikan 4 kecepatan burung yaitu: 75 m/s, 100 m/s, 125 m/s dan 150 m/s, serta 2 variasi sudut sebesar 0 dan 45. Hasil simulasi menunjukan deformasi Leading Edge meningkat dengan bertambahnya kecepatan, serta gaya impact lebih tinggi pada arah tumbukan 0o untuk tiap kecepatan yang sama. Gaya impact maksimum pada tiap kecepatan untuk arah tumbukan 0o dan 45o pada rentang 6 – 17 kN dan 3 – 12 kN. Sementara hasil displacement maksimum pada tiap kecepatan untuk arah tumbukan 0o dan 45o pada rentang 148 – 336 mm dan 89 – 198 mm.

Abstract

The aircraft maintenance business in Indonesia is still very attractive along with increasing number of aircraft on Indonesia airlines. As much as 65% of the aircraft maintenance costs of domestic airlines that have not been absorbed by MRO Indonesia. Most of the unabsorbed portions are aircraft engine and component maintenance clusters which only absorb about 10% (USD 100 Million) of 75% (USD 750 Million Th 2017) engine maintenance costs (35%) and aircraft components (45%), issued by Indonesian airlines. From the 10% uptake of engine maintenance costs and components, the portion of engine maintenance maintenance uptake is only 5% (USD 50 Million) of 35% (USD 350 Million) engine maintenance costs. There is still around 30% (USD 300 Million) which is an opportunity for MRO Indonesia to develop the engine maintenance capability of Indonesian airlines. Based on several types of aircraft engines in Indonesian airlines, CFM56-7B used by B737-800/900 which has the largest population of around 450 engines. From the feasibility analysis on the development of the capability of the MRO engine for maintenance of the CFM56-7B, the ROI and Pay Back Period / PBP calculations for the capability engine development program are 24.57% and 4.4 years respectively. The ROI and PBP show that the CFM56-7B MRO engine development strategy is feasible.

Abstract

Many causes of aircraft accidents one of which is the failure of the aircraft to operate normally due to the age of the aircraft that is old. Stipulation of aircraft age restriction regulations are applied to reduce the number of aircraft accidents. The aircraft owned by Whitesky Aviation, the Cessna 402B is an aircraft used for aerial photography activities. Age restrictions on aircraft that are prohibited from operating are 45 years. Calculation of flight hours of the Cessna 402B according to current data records if an estimate is made when reaching the age of 45, the condition of the aircraft is still in good condition. So that age-limiting regulations are not appropriate to apply if applied to aircraft that only have low flight hours. At the writing of this final project aims to determine the influence of the age of the Cessna 420B on operational and maintenance and age limits in accordance with the comparison of maintenance schedule according to Flight Hours and Flight Cycle. And in low utilization operations there is no difference in aircraft operations based on aircraft age, aircraft utilization does not affect the number of maintenance according to the calender time and the age limit of the aircraft has not been reached so that it still has a lot of remaining life. PK-WLW aircraft have a remaining life of 29882.4FH and PK-WLY aircraft have a remaining life of 31405.2FH

Abstract

Performa tinggal landas dan mendarat merupakan aspek penting dalam pengoperasian pesawat terbang, terutama terkait kebutuhan panjang landasan (runway requirement). Faktor-faktor seperti berat pesawat, elevasi landasan, dan kondisi permukaan runway menjadi parameter utama dalam menentukan kebutuhan panjang landasan yang optimal. Penelitian ini bertujuan untuk menganalisis performa tinggal landas dan mendarat (field performance) pesawat Airbus A350-XWB pada beberapa bandara di wilayah Yaman, yaitu Bandara Aden, Sanaa, dan Socotra, dengan mempertimbangkan perbedaan elevasi masing-masing bandara. Analisis dilakukan dengan pendekatan perhitungan kebutuhan panjang landasan berdasarkan data spesifikasi teknis pesawat dan tabel parameter International Standard Atmosphere (ISA). Hasil penelitian menunjukkan bahwa spesifikasi dan karakteristik pesawat Airbus A350-XWB serta mesin Rolls-Royce Trent-XWB telah diperoleh melalui aplikasi resmi masing-masing. Analisis performa pesawat pada tiga bandara di Yaman menunjukkan bahwa panjang landasan yang dibutuhkan saat lepas landas bervariasi, yaitu 2910,69 m di Bandara Aden, 2951,04 m di Bandara Sana’a, dan 2955,5 m di Bandara Socotra. Sementara itu, kebutuhan panjang landasan saat pendaratan relatif seragam di ketiga bandara, yaitu sekitar 2628,8 m. Perbedaan panjang landasan yang dibutuhkan terutama dipengaruhi oleh elevasi bandara yang berpengaruh terhadap densitas udara, di mana semakin tinggi elevasi suatu bandara, semakin panjang landasan yang dibutuhkan untuk proses lepas landas dan pendaratan.   Takeoff and landing performance are important aspects of aircraft operation, especially concerning runway requirements.  Factors such as aircraft weight, runway elevation, and runway surface conditions are the main parameters in determining the optimal runway length requirement.  This study aims to analyze the takeoff and landing performance (field performance) of the Airbus A350-XWB at several airports in Yemen, namely Aden Airport, Sanaa, and Socotra, taking into account the elevation differences of each airport.  The analysis was conducted using an approach to calculate the runway length requirements based on the aircraft's technical specifications and the International Standard Atmosphere (ISA) parameter table. The results of the study show that the specifications and characteristics of the Airbus A350-XWB aircraft and the Rolls-Royce Trent-XWB engine have been obtained through their respective official applications. Analysis of aircraft performance at three airports in Yemen shows that the runway length required for takeoff varies, namely 2910.69 m at Aden Airport, 2951.04 m at Sana'a Airport, and 2955.5 m at Socotra Airport. Meanwhile, the runway length requirement for landing is relatively uniform at the three airports, which is around 2628.8 m. The difference in runway length required is mainly influenced by the elevation of the airport which affects air density, where the higher the elevation of an airport, the longer the runway required for the takeoff and landing process.

Abstract

The main battery on the CRJ-1000 aircraft is an important component in the aircraft's electrical system. The main battery functions as the main source of electric power when the aircraft is turned off or when the aircraft engine is not operating. If there is a failure in the aircraft's battery it can cause disruption to other systems so that the aircraft cannot fly or Aircraft on Ground (AOG). In Garuda Indonesia's CRJ-1000 aircraft battery, there were several findings where the battery failed before reaching the scheduled removal time. This study aims to analyze the reliability of the CRJ-1000 main battery on the Garuda Indonesia airline. The analytical method is carried out by collecting historical data on main battery failures and calculating the Mean Time Between Failure (MTBF) and Availability values for a certain period. In addition, an analysis was also carried out on maintenance procedures and replacement of the main battery carried out by Garuda Indonesia airline technicians. The results of the analysis show that the MTBF of the CRJ-1000 main battery on Garuda Indonesia airlines has a fairly good value, but there is a need for improvement in maintenance procedures and replacement of the main battery to increase availability. The recommendations proposed are evaluating the main battery maintenance and replacement procedures, as well as increasing the availability of main battery spare parts which can speed up repair times in failure situations.
