An aircraft is considered one of the most sophisticated combinations of complex technologies and is known as the safest and fastest mode of transportation. The aviation industry reached such a safety level by implementing continuous innovation and improvement in flying technologies embedded during aircraft production. Along with production, the aircraft manufacturer's team also establishes aircraft maintenance requirements to keep the aircraft airworthy during its life span. Soon after the aircraft's delivery to its owner or operator worldwide, the owners'/operators' responsibility is to maintain the aircraft and ensure airworthiness by performing the maintenance work at predefined intervals. Such maintenance activities are defined in two categories and performed by aircraft engineers under the Part-145 framework and aircraft maintenance organizational setup. The first category is line maintenance, which is comparatively light regarding the nature of work, and the second is base maintenance, which takes all the major work needed on the aircraft. This research paper will discuss the significance and challenges in aircraft base maintenance engineering within the aviation industry.

A massive gap exists between aircraft maintenance planning functions and aircraft maintenance engineering services. The airline industry requires a more effective solution to improve the utilization and efficiency of their maintenance planning and maintenance engineering personnel so that aircraft maintenance turnaround time can be reduced to the optimal level, as it is a significant factor contributing to improving aircraft serviceability and availability for more revenue flights and generate more business. This exploratory study evaluated the significance of maintenance planning within the airline industry. It aimed to find a solution to reduce the time spent in maintenance management in the turnaround process. It also attempted to discover opportunities for airlines to follow a proactive approach in identifying problems early, thus improving overall aircraft efficiency and reducing lost time.

In the context of the aircraft Maintenance Repair and Overhaul (MRO) industry, Supply Chain Management (SCM) is paramount, as timely aircraft release per contractual agreements is imperative. Nevertheless, adhering to agreed-upon schedules remain a formidable challenge for MRO operations due to SCM-related issues, primarily delays in procuring aircraft components and inventory management complexities. This research paper is primarily dedicated to investigating two core aspects: the first one is the management, and the second one is the implementation of innovative tools in the supply chain domain, encompassing a broad spectrum of concerns. The findings of this study assess the impact of SCM on aircraft maintenance turnaround time, employing statistical analysis as the primary methodology.

The turnover time for aircraft maintenance is crucial for the operational efficiency and profitability of airlines. Quality assurance (QA) and quality control (QC) procedures play a role in assuring the safe and reliable operation of aircraft. The purpose of this paper is to evaluate the impact of QC and QA on turnover time and to propose strategies for achieving a balance between quality and efficiency. A large-scale survey of airline and aviation maintenance organization maintenance staff was combined with a literature study to form a mixed-methods strategy. The findings indicate that quality control and quality assurance have a substantial impact on the turnaround time for aircraft maintenance. Standardization, automation, collaboration, training, and regulation were identified as obstacles and best practices for enhancing QC and QA. Recognizing the intricate relationship between QC, QA, and turnaround time, the paper concludes by recommending future research and practices to enhance aircraft maintenance quality and efficiency.
