Periodic Reporting for period 1 - WISE (A novel approach to remote and real-time aircraft maintenance)

Teaser

Summary

The project WISE will develop and demonstrate a unique service: the first remote and live expert assistance accessible to aircraft maintenance operators, whatever their location, whatever the type of maintenance or repair operation and whenever needed (24/7 on the wing service). It is expected to disrupt the traditional market of Maintenance, Repair and Overhaul (MRO) by turning it predictive, expert and accessible to any operator.

The 24-month project will address five major objectives:
1. To demonstrate the adaptability of the disruptive service to the MRO operators on any aircraft maintenance site,
2. To scale up the number of sites connected with the WISE center,
3. To fully engage the stakeholders in the WISE project,
4. To foster market uptake by increasing awareness of the transformative impact of the approach in the aircraft maintenance sector,
5. To maximize value creation from the WISE approach.

Work performed

At the end of the first reporting period, SUNAERO has achieved the first main technical and regulatory steps of the WISE project:
- The technical teams have been focusing on the validation of the different elements, which compose the WISE system. They have validated the prototype system integrated with new communication and optimized maintenance features and certified tools.
- Successful performance tests have been carried out to assess the usability of the system in first relevant use cases. The tests enabled to validate the relevance and the early compliance of the systems specifications
- The WISE database has been designed to provide predictive insights on a large majority of maintenance use cases
- The Service application guidelines have been defined.

Final results

In the last decade, the aircraft industry has been facing fundamental maintenance dilemmas:
- Maintenance expertise is missing in more than 21â€™000 airports worldwide whereas the number of commercial aircrafts on duty is inexorably growing (more than 43,000 aircrafts by 2030 , twice the volume of the current fleet).
- Aircraft On Ground (AoG) for structural maintenance is a persisting financial burden : AOG costs 120 000â‚¬ per day to airline companies . Maintenance Repair and Overhaul (MRO) operators have to work under time pressure, thus augmenting the risk of defaulting repair.
- Today structural repair on AoG unavoidably requires to bring external experts physically on site. It takes 1 to 2 days for the expert to actually arrive and 2 to 10 additional days to have the aircraft repaired and allowed back in the air. Complex structural repair on AoG (for example composite or engine repair) can even last several weeks because the MRO operator has not been trained to specific non-recurring operations and does not have the proper maintenance equipment in hand.

The level of maintenance skills onsite needs to increase dramatically and rapidly, otherwise the aircraft industry can expect a huge economic loss due to inappropriate structural maintenance on AoG.
The WISE system developed in this project will make it possible to give a remote access to any airport (line maintenance) or MRO site to a maintenance expert center and/or to a knowledge database, whenever needed. The system will have been extensively tested to ensure operation from a remote control center, accessible 24h/7d to instantaneously guide the repair until it is fixed a few hours later (8 hours on average), and tracking all activities done on the field for records and
knowledge improvement.
