EVALUASI POLA KOROSI PADA NARROW BODY AIRCRAFT MENGGUNAKAN METODE PARETO ANALYSIS

---

The structure of a current aircraft is composed of 80% aluminum and 20% composites. Aluminum is a non-ferrous metal known for its corrosion resistance and light weight. Furthermore, aluminum alloys are easy to manufacture and have a high strength-to-weight ratio (GMF, 2018). An aircraft requires lightweight materials to reduce weight and improve fuel efficiency. Structural corrosion that occurs in the environment is almost always an electrochemical process. The electrochemical process that occurs on the surface of the corroded object is called an electrode. The liquid that induces ionization is called an electrolyte. The resulting electrochemical reaction causes a change in the valence between the two elements. The research method used in this study was experimental. This study examined corrosion occurring on the Boeing 737 NG aircraft. The aluminum materials commonly used are Aluminum 2024-T3 and Aluminum 7075-T6. The standard analysis used the Pareto analysis method to evaluate the corrosion patterns occurring on the Boeing 737 NG aircraft. Based on research data and discussions conducted on the Boeing 737 NG aircraft, it can be concluded that the corrosion pattern of the Boeing 737 NG aircraft is as follows. 1. Of the total aircraft damage cases on Boeing 737 NG aircraft, 818 were found to be due to corrosion. Furthermore, of the 818 cases, 641 affected the skin. 2. A total of 633 cases of corrosion occurred in zone 100. The main cause of corrosion was environmental in 497 cases. Zone 100 is the lower zone of the aircraft, corrosion often occurs due to environmental factors (humidity and condensation).
