Abstract

Kecelekaan Pesawat TWA 800, sebuah Pesawat Boeing 747 pada 17 Juli 1996 disebutkan disebabkan karena bahan bakar yang mengalami ledakan di dalam tangki sayap tengah. Karena kecelakaan tersebut, Federal Aviation Administration (FAA) melakukan evaluasi guna meningkatkan persyaratan keamanan tangki bahan bakar pesawat komersial. Salah satu cara yang direkomendasikan oleh National Transportation Safety Board (NTSB) adalah mempertahankan bahan bakar yang cukup di tangki bahan bakar pesawat supaya peningkatan suhu bahan bakarnya bisa dibatasi sehingga bahan bakar selalu ada di bawah batas ledakan. Dari evaluasi tersebut, kemudian FAA membentuk Fuel Flammability Task Group. Yang memiliki tugas untuk meninjau data mengenai ledakan bahan bakar Jet A di tangki pesawat dan energi minimum yang diperlukan Jet A untuk memulai ledakan. Penelitian ini menggunakan metode pengumpulan data yang diambil dari data flight test pesawat N-219 yang telah dilakukan oleh PT Dirgantara Indonesia. Data tersebut kemudian diolah dan dianalisa sesuai dengan grafik yang dihasilkan. Berdasarkan analisa data yang telah dilakukan, diperoleh kesimpulan bahwa Flammability bahan bakar Jet A-1 sangat dipengaruhi oleh suhu dan altitude. Dengan penjelasan semakin rendah suhu, maka energi yang dibutuhkan untuk mencapai titik mudah terbakar akan semakin tinggi, begitu juga dengan altitude-nya. Kemudian untuk energi minimum bahan bakar pesawat N- 219 aman dari ledakan apabila nilai E Ignation-nya di bawah 10 mJ. ============================================================================================ The TWA 800 aircraft accident, a Boeing 747 on July 17, 1996, was said to have been caused by an explosion of fuel in a central wing tank. Because of the accident, the Federal Aviation Administration (FAA) conducted an evaluation to improve the safety requirements of commercial aircraft fuel tanks. One method recommended by the National Transportation Safety Board (NTSB) is to maintain sufficient fuel in the aircraft's fuel tank so that the increase in fuel temperature can be limited so that fuel is always below the explosion limit. From this evaluation, the FAA then formed the Fuel Flammability Task Group. Which has the duty to review data regarding Jet A fuel explosions in aircraft tanks and the minimum energy required by Jet A to start the explosion. This study uses data collection methods taken from N-219 aircraft flight test data conducted by PT Dirgantara Indonesia. The data is then processed and analyzed in accordance with the resulting graph. Based on the analysis of the data that has been done, it can be concluded that the Flammability of Jet A-1 fuel is strongly influenced by temperature and altitude. With the explanation of the lower temperature, the energy required to reach the flammable point will be higher, as well as the altitude. Then for minimum energy the N-219 fuel is safe from explosion if the value of E Ignation is below 10 mJ
