CINNABAR Project: Cost-Benefit Analysis of digital Processes for non-destructive Inspections of Aircraft Structures

Kurzfassung

The outlined study focuses on the cost-benefit analysis of implementing digital processes for structural aircraft inspection using state-of-the-art laser-scanning technology, augmented reality (AR), and digital twins. Traditional aircraft inspection methods need to meet high quality standards in terms of accuracy, reproducibility and documentability and are therefore known to be time-consuming and labour-intensive, leading to high costs and potential safety risks related to human factors. By substituting manual maintenance tasks through digitally supported approaches and implementing a digital thread, the inspection processes can be streamlined and made more efficient. This publication aims to analyse the initial investment effort required for implementing these digital processes and compare it to the potential cost savings and benefits in terms of working time and quality. Different process modifications to the current dent-and-buckle inspection process are proposed and closely analysed. The findings of this analysis will offer valuable insights for aircraft maintenance companies and decision-makers regarding the feasibility and potential benefits of adopting digital processes for structural aircraft inspection.
