CASE STUDY

Quality event management (QEM) in Aeronautics

ALTEN Polska experts were instrumental in managing Quality Events (QEM) for a leading aircraft engine manufacturer, assessing the impact of non-compliant components on engine safety and reliability. Through advanced engineering expertise and seamless coordination, we minimized operational risks and reduced costs for the client.

As part of the project, ALTEN Polska delivered comprehensive mechanical engineering support, including a wide range of technical analyses such as strength assessments and close collaboration with multiple departments. Our expertise ensured fast, accurate engineering recommendations, enabling most components to remain in service.

Challenge

Evaluate the impact of non-compliant parts already installed in engine assemblies—without delaying delivery schedules.

Solution

Advanced fatigue and dimensional chain analyses
Strength calculations and statistical methods
Close cooperation with client teams and suppliers
Rapid risk assessment and decision-making

Benefits

Reduced engine shipment downtime
Lower disassembly and repair costs
Fewer scrapped components
Maintained delivery schedule
Full compliance with regulatory and quality standards

Project challenges and impact on end users

Quality Event Management in aviation is a critical process—every non-conformance can affect flight safety. In this project, the challenge was to quickly and accurately determine whether components with non-conformities, which were not intercepted by quality control and reached the final product, could remain in use.

Thanks to ALTEN Polska’s technical knowledge and experience, operational risk was reduced, and the need for part disassembly was minimized—without compromising engine safety and reliability.

Applied tools and engineering solutions

The ALTEN Polska team utilized advanced engineering tools such as Siemens NX (3D modeling), FEM analysis (Ansys), dimensional chain analysis, and statistical methods. Fatigue analyses (LCF/HCF) and crack propagation studies were also conducted. Gathering complete technical documentation from suppliers and coordinating actions with production, assembly, and aerodynamics departments was crucial. The final outcome was an MRB disposition recommendation (use as is / rework / repair / reject) approved by the client.

Benefits for the client and end users

With ALTEN Polska’s support, the global aircraft engine manufacturer gained not only a technical solution but also strategic quality management assistance. The project enabled:
