At present, the use of information and communication has become an everyday thing. There are many types of applications, for instance, in an activity as simple as going to run, we can plan our route, go running while following the planned route and receive voice messages from friends that encourage you to complete the route. At the end, you can upload your results in social networks and get a weekly summary of your achievements. All this information is stored in databases and can also be used. In a maintenance centre PART-145 such as Habock Service & Support, which provides technical support and support to all operators of the Habock Aviation Group [1] (TAF Helicopters, Helicopteros Insulares, CoyotAir, Habock Argentina), the data have a large volume. To date, office automation tools have been used and have worked, but when the workload increases, a change in the way of data is processed, to extract valuable information for decision making is needed. The aim of this project is to design an application for the Habock Service & Support Quality department, which centralizes all the available information of the department and that serves to help comply with the regulations of ANNEX II (PART-145) which EASA requires a maintenance centre. In addition, this application will have functions that increase the efficiency of the personnel involved. To achieve this objective, the requirements that EASA requires of a PART 145 maintenance centre and which the Quality department must comply with have been studied. Then, the modelling of a database that encompasses all the requirements and reflects the maximum possible workflow used by the department, so as to minimize the impact on the personnel of the department Quality. The choice of the programming language, the database and the client-server model have been made after a small analysis among the available resources, being the Symfony framework, the MySQL database, the Apache server and the JasperReport Server reporting server the chosen ones. With Doctrine, which is part of the Symfony framework, we have proceeded to declare all the entities of the application. Then a CRUD of the entities has been generated. To facilitate interaction with users and thinking about the future, the Boostrap framework has been implemented in version 3.0, which helps us to adapt our web design to any device. We also implemented Select2 in the selection boxes that makes interaction with users more obvious and faster. One of the most important parts of the project, which concerns the increase of the personnel efficiency, has been the implementation of functions such as staff competencies. With the implementation of the report server, our application and data base, we have met all the requirements for Habock Service & Support's Quality department to work in a fast, data-free and efficient way. Finally, the conclusions have been written and a small study has been carried out with the Director of the Quality Department, with a view to expand the application's functionalities, as well as being able to implement it in other areas of the Habock Aviation Group.
