MRO Scenario 3 Repair and modification design – online event student presentations


On the 21st of January, our 4th year Aviation MRO Engineering students are going to present the results of their final project on repair or modification designs. As a result from the ongoing COVID-19 pandemic, this year’s presentation will be held as on online event. The students have been specialising in the field of MRO Engineering during the last semester, as final track before graduation. The students are challenged by industry in real cases. The final 6 weeks the students have been working on cases on “Repair and modification design” provided by DEAC, SPECTO, KLM CS, and the KLM Repair Lab, supported by guest lectures and practical demonstrations by AAR Aircraft Component Services, EASA, EPCOR, JetSupport and TiaT. Register for free to receive an invitation to the event.

During the MRO Engineering specialisation, students are familiarised with the field of aviation MRO through 3 different scenarios: setting up an MRO capability, the optimization of MRO processes, and working on a repair or modification design.

Maintenance organizations carry out the task of keeping the aircraft airworthy through e.g., repair of damages and modifications. To do so, engineers and technicians work with approved data provided by the OEMs such as maintenance manuals, repair manuals, bulletins, directives, and such. However, these documents could never cover all situations as incidents and airline specific usage could result in unique damages or errors. Additionally, these documents, and even aircraft design is being developed over time through aircraft usage worldwide. To resolve problems adequately, reduce time and costs an own strategy may be proposed based on in-house knowledge and experience.

Through this third scenario the students are challenged with an assignment involving a repair or modification request. They will got through the steps from identification and functional analysis to showing compliance to the airworthiness requirements and work instructions for the shop or hangar.
Knowledge of aircraft structures, systems, and components is needed. Why are they designed the way they are? What functions do they have? Before coming up with a solution, designing a repair or modification, as an engineer you should be able to understand the problem first, how it occurred and what is its impact on the aircraft.

The objective is to make use of approved data and have a critical view on requirements and wishes.
When a solution has been found through repair or modification design, an element that should not be overlooked is how this is communicated to the shops and hangar for realisation and solving the problem. Crucial is communication with the authorities, showing compliance and certification to complete the process and guarantee flight safety.

The goal of MRO Scenario 3 is for the students to reach the following learning objectives:
• Analyse the function(s) and build-up of an aircraft part and determine the main loading directions and occurring principal stresses.
• Assess the cause, type and extend of a damage or a modification, the possible effects of the change, and classify the change.
• Analyse the material properties (e.g. physical, mechanical, technological properties) of an aircraft part and propose a suitable, matching repair alternative.
• Create a design, including specification of requirements for the repair or modification, showing compliance with regulations, resulting in a proposal.
• Demonstrate competency by defending the design towards experienced professional experts (both design engineers and aircraft mechanics) using effective and appropriate oral and (industry standard) written communication showing technical understanding and accuracy.
• Demonstrate working knowledge of the process of damage disposition or modifications and/or additive manufacturing techniques by creating unambiguous and executable workplace instructions.
