The Manufacturing Processes of Airbus A320 Landing Gear Bhushings Using Reverse Engineering Methods

The aviation sector is currently enjoying fast growth, as seen by the manufacture of 8,650 Airbus A320 aircraft. One critical component is the landing gear bushing (P/N 201160616), which provides safety and performance during takeoff and landing. PT. GMF AeroAsiaTbk is having difficulty obtaining these bushings due to low stock, configuration changes, and delivery delays. To address this, PT. GMF AeroAsiaTbk, through PMA Holder GMF Aero Asia, intends to produce bushings independently under the Parts Manufacturing Approval procedure outlined in CASR Part 21 Sub-Part K, with DGCA monitoring. Reverse engineering approaches are utilized to overcome technical information restrictions, allowing high-quality bushings to be produced. The research goals are to collect dimensional and material data, develop optimal production methods, and understand the electroplating process on bushings. The reverse engineering procedure entails taking measurements with a vernier calliper and a Coordinate Measuring Machine (CMM) as well as reviewing the Component Maintenance Manual. Preparation, fabrication, inspection, packing, and marking are all part of the production process. Bright cadmium electroplating is used to prevent corrosion and enhance appearance. The findings are expected to improve production efficiency, decrease downtime, and ensure the availability of dependable spare parts.
