Tugas Akhir ini merupakan penyempurnaan Tugas Akhir sebelumnya berupa pembuatan alat bantu pelepasan/pemasangan roda pendarat Grand Commander 680FL bagian Mekanisme Sistem Pneumatik yang sudah dilakukan oleh Novi Surya Ratri (2016) berjudul “Penyelesaian Rancang Bangun Pneumatik Tyre Bead Breaker Tools Untuk Pemasangan/Pelepasan Main Wheel Landing Gear Pesawat Grand Commander 680 FL (Bagian Rancang Bangun Mekanisme Sistem Pneumatik)â€�. Penyempurnaan yang dilakukan adalah pembuatan bagian penahan gerakan tambahan pada mekanisme sistem pneumatik (terpental), penyelesaian permasalahan pada piston penarik serta penyempurnaan desain dudukan silinder pneumatik agar dapat juga digunakan untuk melepas Nose Wheel Landing Gear Pesawat Grand Commander 680 FL. Metode yang digunakan pada Tugas Akhir ini terdiri atas metode analisis dan eksperimental yang meliputi tahap pelaksanaan antara lain: studi literatur, obeservasi dan survei, analisis dan desain, manufaktur dan perakitan, pengujian serta evaluasi dan trouble shooting. Tugas Akhiri ini telah berhasil menyelesaikan rancang bangun Pneumatic Tyre Bead Breaker Tool bersamaan dengan dua TA lain berupa perancangan dan pembuatan bagian pemasangan/penahan dan pelepasan/penarik. Alat bantu yang dihasilkan telah berhasil diuji secara operasional dan fungsional, dimana didapatkan hasil bahwa: panjang langkah piston aktuator sepanjang 100 mm dengan menggunakan tekanan udara sebesar 6-7 bar. Alat bantu yang telah dibuat dapat digunakan dalam perkuliahan praktikum Perawatan Pesawat Udara di Program Studi Teknik Aeronautika-Jurusan Teknik Mesin-POLBAN. Kata kunci: Pneumtic Tyre Bead Breaker, Pneumatic, Wheel Landing Gear Grand Commander 680FL.

This Final Project is the improvement of tire removal and installation tool of wheel landing gear of the aircraft Grand Commander 680 FL (Pneumatic System Mechanism) that had previously been conducted by Novi Surya Ratri on 2016 entitled "Settlement of the Design of the Pneumatic Tyre Bead Breaker Tools For Installation / Removal of Main Wheel Landing Gear Grand Commander 680FL. (Mechanism Pneumatic System Design)". The improvement of the Pneumatic System Mechanism was conducted by the manufacturing of the additional motion absorber of pneumatic system mechanism (bouncing), troubleshooting of the piston's malfunction and also the design improvement of Pneumatic Cylinder's holder for nose wheel's removal. The methods used in the final project are experimental and analytical methods that are implemented by the following steps:literature study, observation and survey, analysis and designing, manufacturing and assembly, testing and the evaluation and trouble shooting. The designing of the Pneumatic Tyre Bead Breaker Tool is successfully conducted as described previously. This Final Project is finished along with two other that finish their own project about installation and removal part. The tool is successfully tested operationally and functionally, where the testing results: stroke of the piston is 100 mm by using 6-7 bars air pressure. The tool is usable for practicing aircraft maintenance course in Aeronautical Engineering Program Study-Mechanical Engineering Department-Bandung State Polytechnic. Keywords: Tyre Bead Breaker, Pneumatic, Wheel Landing Gear Grand Commander 680FL.
