Real-time Condition-based Maintenance for Adaptive Aircraft Maintenance Planning

Periodic Reporting for period 1 - ReMAP (Real-time Condition-based Maintenance for Adaptive Aircraft Maintenance Planning)

Reporting period: 2018-06-01 to 2019-11-30

ReMAP is a European project that started on the 1st of June 2018 and has a duration of four years. The project addresses the specific challenge of replacing fixed-interval aircraft maintenance inspections with adaptive condition-based interventions. In order to achieve this, a data-driven approach will be implemented, based on hybrid machine learning & physics-based algorithms for systems, and data-driven probabilistic algorithms for systems and structures. A similar approach will be followed to develop a maintenance management optimisation solution, capable of adapting to real-time health conditions of the aircraft fleet. These algorithms will run on an open-source IT platform, for adaptive fleet maintenance management. The proposed Condition-based Maintenance solution will be evaluated according to a safety risk assessment, ensuring its reliable implementation and promoting an informed discussion on regulatory challenges and concrete actions towards the certification of Condition-based Maintenance.
The work in the term of the ReMAP project was mainly dedicated to 1) the identification of requirement and specification and 2) the initial developments of the technologies from several Work-packages. In addition to this, 3) a particular effort was given to the dissemination activities and engagement of external stakeholders.

1) The identification of requirement and specifications was common to most Work-packages. This included the identification of the main actors involved in the implementation of a Condition-based Maintenance solution, allowing the definition of the requirements and specifications and the high-level architecture needed for the IT platform. In parallel, the specifications of the experiments and technologies to be developed in the project. For instance, detailed procedures were defined for the laboratory tests associated with the Structural Health Monitoring experiments, while for Prognostics and Health Management, data requirements and exploratory data analytics were presented and discussed in this first part of the project.

2) All Work-packages are running according to the initial project plan and producing initial results. For instance, the sensing technologies proposed have been designed, manufactured and installed in aero-structural coupons. These coupons are currently been used in the initial laboratory tests essential for the development of the data-driven algorithms for aero-structures damage and remaining useful life estimation. The first algorithms to estimate remaining useful life and diagnostics for systems have also been developed and successfully presented in public events. In this initial period of the project, the consortium has also developed an initial deterministic maintenance schedule algorithm, collected a list of hazards and run initial risk assessment analysis .

3) A strong communication and dissemination strategy was created during the first year of the project to create the ReMAP image, launch the communication channels and promote the project next relevant stakeholders. The effort since M12 has refocused on building the ReMAP ecosystem for the discussion of the common roadmap towards the implementation.
ReMAP will define a roadmap towards the implementation of Condition-based Maintenance in aviation. To contribute to this goal, ReMAP’s approach will be tested in a unprecedented 6-month operational demonstration, involving more than 12 systems from two different aircraft fleets. It is expected that ReMAP will have an estimated benefit to the European aviation of more than 700 million Euro per year, due to a direct decrease in maintenance costs, reduced unscheduled aircraft maintenance events, and increased aircraft availability. Furthermore, ReMAP will engage relevant aviation stakeholders in the discussion of the results from the demonstration and the definition of a White-paper for future Condition-based Maintenance implementations.
