Japan Airlines (JAL), JAL Engineering, and CRESCO have jointly developed a system that supports endoscope (borescope) inspections of aircraft engines.
The system automatically extracts images of each individual turbine blade from videos taken during borescope inspections and enables centralized management of these images in the cloud. Building on a borescope inspection support tool that the two companies had been jointly researching since 2019, they further developed it into a web application.
By enabling chronological comparisons with past inspection data and automatic recognition of damage, the system improves both maintenance quality and work efficiency, while visualizing the decision-making criteria of experienced maintenance engineers and helping to pass on their skills to younger staff. By combining the accumulated inspection images with in-flight engine data, the companies aim to realize predictive maintenance that detects early signs of failure and determines the optimal timing for maintenance.
Going forward, companies within the JAL Group that are responsible for aircraft maintenance will take the lead in continuously accumulating data and conducting advanced analyses, refining failure risk assessments and maintenance planning. Through these efforts, they will promote initiatives to achieve safe operations and enhance aircraft safety under the slogan of “Zero Zero 100” (zero irregular operations, zero in-flight failures, and a 100% on-time departure rate).
