Due to the global pandemic that the world is suffering these days, the aeronautical industry is feeling one of the worst crisis ever seen. Many airports are looking for alternative ways to generate money due to the very low passenger aircraft operations. This has brought forward the business model of the current maintenance and storage airports that has achieved better economic results than pre-pandemic times. Besides, the more and more complex aircraft and the continuous growth of the aeronautical sector, excluding the global sanitary crisis, makes aircraft maintenance one of the main potential fields to develop airports with low passenger rates. The content of the project is divided into eight chapters. First, the maintenance and storage airport concept is detailed in order to see what implies and which differences there are between passenger and maintenance airports in terms of infrastructure, capabilities, systems and personnel needed. The second chapter addresses the evolution of the MRO (Maintenance, Repair and Overhaul) market through the years and how it has been changed according to new regulations and necessities. Besides, it includes an MRO market forecast reviewing the estimations and predictions of the market. Chapter three is focused on the business model of these airports through a business model canvas and SWOT analysis. The fourth chapter covers one of the main maintenance and storage airports in Europe, Teruel Airport. It details the main activities performed, the companies operating there and the finance evolution and results of the airport. Chapter five establishes an airport type proposal collecting the common characteristics of the airports and the most important requirements needed to carry out maintenance and storage operations. Chapter six suggest one current airport with low revenues to change its business model in order to improve its results and become a viable facility. Chapter seven includes the conclusions and the recommendations to continue to project and go deeper in the analysis of some aspects. Finally, the future project planning to establish a guideline to continue the project and improve even more the study
