Airctraft defects in production can result in significant financial losses, lead to costly rework, delays, and even safety risks. This study proposes a framework to improve productivity and efficiency in aircraft manufacturing and analyze quality control using machine learning, Six Sigma, and the QCDSME (Quality-Cost-Delivery-SafetyMorale) method. The DMAIC (Define-Measure-AnalyzeImprove-Control) stage is a reference in the implementation steps of the Six Sigma method of the Airbus A320. The sigma value in this study was obtained on average for 40 periods of 4.61 sigma and a DPMO of 1225.69. At the analyze stage, a fishbone diagram is used to find the root cause of the problem. Furthermore, a machine learning analysis was performed using the text mining method to identify the most common product components that frequently have defects in Airbus A320 and identify the main factors causing defects, by the human factor. The enhance stage suggests a rise in overcoming challenges with the QCDSME method. Overall, it was discovered that the number of defects fell while the sigma improved and this method can enhance industry performance. |\n| DOI:\u003Cbr>[https://doi.org/10.31315/opsi.v18i1.13960](https://doi.org/10.31315/opsi.v18i1.13960) | This is an open access article under the CC–BY license.\u003Cbr> |  |\n\n1. INTRODUCTION  \nThe aviation industry, a cornerstone of global transportation, faces relentless pressure to enhance productivity and efficiency while maintaining stringent quality standards. As highlighted by Bhatia et al. [1], the aircraft production need to flexibility, adaptability, and data-driven decision-making has become increasingly apparent. Stringent safety regulations, complex supply chains, and the need for continuous innovation have intensified the pressure on manufacturers to deliver high-quality aircraft on time and within budget. The complex nature of aircraft manufacturing involves numerous processes, components, and  \nsuppliers, making it difficult to optimize the overall production flow. Inefficiencies can result in increased costs, longer lead times, and reduced customer satisfaction.  \nThe aviation industry faces a critical challenge in ensuring the quality and reliability of aircraft products. Defects and low-quality components can lead to serious consequences, including safety risks, operational disruptions, and increased maintenance costs. According to a study by the International Civil Aviation Organization (ICAO), aircraft defects can result in significant financial losses for airlines, with an estimated global cost of over $100 billion annually. Defects and non-conformances can lead to costly rework, delays, and even safety risks. For instance, a study by the European Aviation Safety Agency (EASA) found that manufacturing errors are the leading cause of aircraft defects, accounting for approximately 40% of all incidents.
